<content:encoded><![CDATA[<div class='snap_preview'><p>If I hear the word &#8220;mammogram&#8221; one more time&#8230;</p>
<p>The news really does beat a subject to death.  Whatever the hot topic of the moment &#8211; Balloon Boy, Sarah Palin, Ms. California, Elliot Spitzer, H1N1 &#8211; news outlets bring in experts, interrupt with special reports, host discussion panels, conduct polls, interrupt their special reports with special reports and find one ridiculous angle after another to keep the story alive.  I find myself searching for a station or channel that isn&#8217;t in the tank for whatever subject finds itself in the spotlight, eventually having to settle for televangelists or Nickelodeon.</p>
<p>I would like a radio or TV station that refuses to utter one word about the current Hot Topic.</p>
<p>I remember a day when the words &#8220;maverick&#8221; and &#8220;change&#8221; didn&#8217;t make me cringe.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p><img class="alignleft size-full wp-image-378" title="spitzer" src="http://thebaezareport.wordpress.com/files/2009/11/spitzer.jpg" alt="spitzer" width="199" height="208" /><br />
Hace unos días asistí a la mejor conferencia que he presenciado en Harvard hasta la fecha.  El ponente era <strong>Eliot Spitzer, ex-Fiscal General del Estado de Nueva York (1996-2006) y ex-Gobernador de Nueva York (2006-2008).</strong> En marzo de 2008, durante la mitad de su mandato como gobernador, Spitzer tuvo que dimitir a su cargo tras haber mantenido una relación con una prostituta.</p>
<p><em>Ver artículo en El Mundo sobre su escándalo y dimisión:</em> <a href="http://www.elmundo.es/elmundo/2008/03/12/internacional/1205336201.html">http://www.elmundo.es/elmundo/2008/03/12/internacional/1205336201.html</a></p>
<p><em>Ver artículo en el New York Times</em>: <a href="http://www.nytimes.com/2008/03/10/nyregion/10cnd-spitzer.html?_r=1">http://www.nytimes.com/2008/03/10/nyregion/10cnd-spitzer.html?_r=1</a></p>
<p><img class="alignright size-full wp-image-381" title="11spitzer04_600" src="http://thebaezareport.wordpress.com/files/2009/11/11spitzer04_600.jpg" alt="11spitzer04_600" width="450" height="210" /></p>
<p>Salvando el tema del escándalo, que fue una tremenda metedura de pata y que ha truncado su carrera política, este señor es un gran orador, culto, divertido y extremadamente inteligente.  <strong>Es el tipo de persona que motiva a los demás cuando esta encima de un estrado hablando</strong>.</p>
<p>Spitzer, en su etapa de Fiscal General de Nueva York, lideró una revolución sin precedentes en la lucha contra el fraude fiscal.  <strong>Era la persona que todo el mundo en Wall Street temía</strong>.  Se ganó el pulso por sus grandes demandas contra los gigantes de Wall Street. Luchaba y defendía los intereses de los pequeños accionistas frente a los grandes y temidos CEOs y demás miembros de los consejos de administración de las grandes corporaciones.</p>
<p><strong>Se le considera la persona que mejor ha puesto en práctica el <em>corporate governance</em></strong> (&#8220;gobierno corporativo&#8221;).  Para él, solo el gobierno puede &#8220;<em>enforce rules letaing to integrity and transparency in the marketplace</em>&#8220;. &#8220;<em>Only government can get these companies to tell the truth</em>&#8220;.</p>
<p>Spitzer, sin pelos en la lengua, criticó a la Administracion Obama por la falta de punteria a la hora de atacar la crisis.  Para el, Obama debe invertir más dinero en la creación de empleo e infraestructuras, y no en rescatar bancos de inversión y otras empresas que se encuentran en bancarrota. </p>
<p><strong>Yo estoy totalmente de acuerdo con él</strong>.  Obama, con los impuestos de todos los ciudadanos de EE.UU. dió a Goldman Sachs $12billones y a AIG otros $182 billones.  Él sugerió que con este dinero se pueden hacer infinidades de cosas diferentes que realmente ayuden a la sociedad y a los contribuyentes americanos. Por ejemplo, invertiría en la creación de coches electricos, que daría trabajo a personas y que es un futuro que ya está aqui.  Invertiría en empezar a poner estaciones de recarga de vehiculos eléctricos por todas las autopistas.</p>
<p>Os dejo con otras frases que me parecieron interesantes: &#8220;<em>Corporate governance is at the heart and soul of what has failed the nation&#8217;s economic system over the last quarer century</em>&#8220;. &#8220;<em>Too big to fail is too big not to fail. Whan companies get that gib, they are inevitably going to fail, bacause you can&#8217;t manage them</em>.&#8221;</p>
<p>Personalmente creo que es una persona, pese a su dimisión por el escandalo hace un ano, que va a dar mucho que hablar.  No tengo ninguna duda de que, tarde o temprano, saltará de nuevo a la politica nacional americana.  Sinceramante, en el plano estrictamente profesional, este país necesita a personas como Spitzer.  Es todo un lider, con ideas claras y serias.</p>
<p>En la actualidad, Spitzer es profesor de &#8220;<em>law and public policy</em>&#8221; en la City College of New York y escribe columnas en el diario digital &#8220;<em>Slate</em>&#8220;.  Ver sus articulos recientes: <a href="http://www.slate.com/?id=3944&#38;qp=49481">http://www.slate.com/?id=3944&#38;qp=49481</a></p>

<content:encoded><![CDATA[<div class='snap_preview'><p>CAMBRIDGE, Mass.,  Nov. 13 (UPI) &#8211;<br />
<P>Former New York Gov. Eliot Spitzer, in an ethics talk Thursday at Harvard University, tried to avoid talking about the scandal that brought him down.</P><br />
<P>Spitzer, who became known for a hardnosed attitude toward Wall Street when he was state attorney general, discussed business ethics, The New York Times reported. But one of the last questions came from a man who asked if Spitzer believed someone&#8217;s agenda was behind the leaked federal investigation into the governor&#8217;s dealings with escorts.</P><br />
<P><Q>Whatever may have led to their being public didn&#8217;t relate to anything I did and doesn&#8217;t excuse it,</Q> Spitzer responded, saying he resigned because it was right to do so.</P><br />
<P>Spitzer was invited to speak by Lawrence Lessig of The Edmond J. Safra Foundation Center for Ethics. Kristin Davis, owner of the escort service Spitzer used, sent a letter of protest to Lessig, the New York Daily News said.</P><br />

<content:encoded><![CDATA[<div class='snap_preview'><p><img src="http://adriabl.wordpress.com/files/2009/11/galaxia-por-hubble-spitzer-i-chandra.jpg" alt="Galàxia por Hubble, Spitzer i Chandra" title="Galàxia por Hubble, Spitzer i Chandra" width="600" height="350" class="aligncenter size-full wp-image-1325" /></p>
<p>FUENTE &#124; <a href="http://www.abc.es/20091111/ciencia-tecnologia-espacio-sistema-solar/tres-telescopios-consiguen-imagen-200911111023.html">abc.es</a></p>
<p>Es cierto que, últimamente, las agencias espaciales de todo el mundo parecen estar en plena competición para ver cuál de ellas es capaz de conseguir la imagen más espectacular de nuestra galaxia. Pero en esta ocasión la NASA ha conseguido superar todo lo que se había hecho hasta el momento. La imagen de arriba muestra, una vez más, una vista espectacular del centro de la Vía Láctea, la galaxia a la que pertenecemos y nuestro hogar en el universo. Pero lo hace de una forma muy especial, ya que la fotografía es, en realidad, la suma de tres imágenes diferentes obtenidas por los tres telescopios espaciales más potentes de la agencia espacial norteamericana: El Spitzer, el Hubble y el Chandra.<br />
Cada uno de ellos, observa y fotografía el cielo en una longitud de onda distinta: El Spitzer lo hace en el rango de los infrarrojos, el Hubble en el espectro visible y el Chandra en la longitud de onda de los rayos X. Así, observando los objetos en estas tres «luces», ningún detalle escapa a los astrónomos. Muchas emisiones de energía, restos de antiguas supernovas o halos alrededor de estrellas masivas «brillan» sólo si se los observa en la longitud de onda adecuada, permaneciendo invisibles en todas las demás.<br />
Por eso, y para poner el broche de oro a la celebración del Año de la Astronomía (que conmemora el 400 aniversario de la primera vez que Galileo apuntó, en 1609, su telescopio hacia el cielo), la NASA ha realizado, por primera vez, el ejercicio de fotografíar la zona central de nuestra galaxia por separado con cada uno de sus tres grandes telescopios espaciales. Y después ha unido las tres fotografías en una sola y única imagen que muestra como nunca se había hecho el turbulento núcleo de nuestro enorme hogar espacial.<br />
Para lograrlo, expertos de los tres observatorios han colaborado estrechamente en la ardua tarea de ensamblar cuidadosamente la imagen final a partir de las obtenidas por cada uno de los tres instrumentos por separado. El resultado es quizá la vista más detallada (y bella) que existe del misterioso corazón de nuestra galaxia.<br />
En ella, los penetrantes ojos del Spitzer y del Chandra (capaces de «ver» a través de la materia) atraviesan las densas y oscuras nubes de gas y polvo que rodean el núcleo galáctico y muestran su inusitada actividad. El centro exacto de la Vía Láctea está situado a la altura de la blanca y brillante región de la derecha y justo debajo del centro de la fotografía.<br />
Si se observa con detenimiento, la fotografía muestra todas las fases de la evolución estelar, desde las oscuras regiones donde las estrellas nacen, a los miembros más fogosos, jóvenes y brillantes de la familia, pasando también por los más veteranos y fríos. Todos, sin excepción, víctimas de las enormes fuerzas generadas por el gigantesco agujero negro que reina en el centro de la Vía Láctea. Con cuatro millones de veces la masa de nuestro sol, este auténtico monstruo zarandea el espacio que le rodea y somete a las estrellas que hay en él a unas tensiones y actividad inusitadas, al ritmo que marca su enorme fuerza gravitatoria.<br />
En el rango de los rayos X, un pálido y difuso halo de color azul permea toda la región. Son inmensas nubes de gas, calentadas hasta una temperatura de millones de grados tanto por la acción del gran agujero negro como por los vientos ardientes de estrellas masivas y explosiones de supernovas. La luz infrarroja, por su parte, revela la presencia de más de cien mil estrellas agrupadas a lo largo de gigantescas nubes de polvo que brillan en tonos rojizos y que forman complejas estructuras que van desde glóbulos compactos de materia a largos filamentos y zonas alargadas, como inmensos dedos apuntando al vacío, que los astrónomos llaman «pilares de la creación» y donde las nuevas estrellas nacen, rompiendo con su brillo recién estrenado los oscuros cascarones de polvo y gas donde se formaron.<br />
Todo, en suma, en una única, nunca vista y seguramente irrepetible imagen que, como mínimo, debería darnos mucho en qué pensar&#8230;</p>

Soirée glamour en compagnie de politiciens, juges, vedettes, des athlètes professionnels. Champagne, diamants et vêtements de luxe.</p>
<p>Dany Doucet nous présente aujourd’hui un reportage dans le Journal de Montréal sur Natalie McLennan, dit Natalia, Escorte de luxe au New York Confidential. Natalia a fait la couverture du magazine New York après le scandale sexuel du gouverneur Spiltzer avec l’escorte de luxe Ashley Dupré de la même agence d’escorte.</p>
<h3>Escorte de luxe et médias</h3>
<p>Très populaire et médiatisée à New York, Natalie McLennan a passé à Larry King Live, Entertainment Tonight, Paula Zahn à CNN… Natalia sera bientôt connu à Montréal avec la sortie de son livre <em>Le Prix à payer</em>, aux Éditions de l’Homme.</p>
<p>Natalie McLennan nous ramène une dure réalité:</p>
<blockquote><p>Au début je voulais ramasser 10 000$ pour repartir ma vie. Puis ce fût 100 000$.</p></blockquote>
<h3>Prostitution et prison</h3>
<p>Un objectif qu’elle a faillit atteindre avant que tout ne s’effondre. Natalie “Natalia” McLennan se retrouve en prison. Tout perdre, devoir recommencer sa vie. Son message est sans équivoque: ne pas sous-estimer la difficulté de quitter le milieu, le style de vie, la consommation de drogue.</p>
<blockquote><p>Je ne conseille pas cette vie à personne, car je suis chanceuse d’être en vie. Plusieurs filles qui font se métier-là meurent prématurément.</p></blockquote>
<p>La prostitution de luxe en attire plus d’une. Souvenons-nous de Sonia, étudiante universitaire. Sonia a fait de la <a title="prostitution de luxe, escorte, prostituée prostituées" href="http://raymondviger.wordpress.com/2008/07/11/prostitution-de-luxe-les-hauts-et-les-bas-dune-escorte/"><strong>prostitution de luxe</strong></a>. 4 000$ le week-end pour coucher avec des politiciens. Elle a tout perdu elle aussi. Le Québec étant moins éblouissant que New York, le taux de change pour une escorte passe de 30 000$ à 4 000$.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Database misuse: <strong>who watches the watchers?</strong><br />
By Matthew Tanase, SecurityFocus • </p>
<p>I have always been continually asking: ‘Where do we draw the line <strong>between ethical hacking and spying?’ </strong>or is there really such a thing as ‘ethical’ hacking?:</p>
<p>‘…So <strong>what can we do?</strong> Every situation is different, which means there&#8217;s no easy, all-encompassing answer. One of the more clever security ideas I&#8217;ve seen in a while comes from <strong>Lance Spitzer of Honeynet fame </strong>- the Honeytoken. Basically they&#8217;re <strong>bogus entities</strong> (such as database records, files, spreadsheet entries) that trigger an alarm when accessed.</p>
<p>&#8216;This is a great idea for <strong>catching someone</strong> doing some rather broad snooping, but it still wouldn&#8217;t have worked for the scenarios described above. Obviously we can increase access control and audit trails, but <strong>reviewing such data for abuse is a daunting, if not impossible </strong>task. In an ideal world, restricted information would be encrypted and available only on a need-to-know basis, but I&#8217;ve yet to come across an <strong>&#8220;ideal&#8221; system combining proper authentication, access and audit controls…’ </strong> see full article at <a href="http://theregister.co.uk">The Register</a></p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Après des millénaires d&#8217;observation du ciel à l&#8217;oeil nu, la lunette de Galilée et les grands télescopes nous ont permis de voir des objets beaucoup plus lointains et beaucoup moins lumineux, mais toujours &#8220;visibles&#8221;.</p>
<p>L&#8217;atmosphère diffusant les infrarouges et nous protégeant des rayonnements ultraviolets et à haute énergie, les seuls autres rayonnements que nous pouvons capter au niveau du sol sont les ondes radio et millimétriques. Mais depuis quelques années, les instruments placés en orbite permettent de fournir des informations sur le cosmos qu&#8217;il serait impossible d&#8217;obtenir depuis le sol.</p>
<div id="attachment_1369" class="wp-caption aligncenter" style="width: 385px"><a href="http://www.insu.cnrs.fr/co/files/f1583pdfinfographie-journal-cnrs-presentant-differents-moyens-observation-utilises-astronomie-fonction-spectre-electromagnetique-avec-legendes.pdf"><img class="size-full wp-image-1369" title="ib2805,infographie-journal-cnrs-presentant-differents-moyens-observation-utilises-astronomie-fonction-spectre-electromagnetique" src="http://drgoulu.wordpress.com/files/2009/10/ib2805infographie-journal-cnrs-presentant-differents-moyens-observation-utilises-astronomie-fonction-spectre-electromagnetique.jpg" alt="ib2805,infographie-journal-cnrs-presentant-differents-moyens-observation-utilises-astronomie-fonction-spectre-electromagnetique" width="375" height="247" /></a><p class="wp-caption-text">infographie du CNRS. Cliquer pour pdf haute résolution annoté</p></div>
<p>Désormais, nous sommes capables de capter les photons de toutes les fréquences, donc de toutes les énergies. Ces instruments combinés aux techniques d&#8217;imagerie informatique élargissent le spectre des couleurs visibles à l&#8217;œil en produisant des images visibles à partir de rayonnements invisibles.</p>
<p>Voici  un petit tour d&#8217;horizon des principaux instruments qui complètent Hubble et les télescopes optiques traditionnels, illustré avec les dernières images qu&#8217;ils ont fourni.</p>
<p>Dans l&#8217;infrarouge, la découverte par <a href="http://fr.wikipedia.org/wiki/Spitzer_%28t%C3%A9lescope_spatial%29" target="_blank">Spitzer </a>d&#8217;un gigantesque anneau de poussière entourant Saturne montre qu&#8217;on peut encore découvrir des choses surprenantes dans notre propre système solaire. (L&#8217;image ci-dessous est un dessin d&#8217;artiste, la <a href="http://gallery.spitzer.caltech.edu/Imagegallery/image.php?image_name=ssc2009-19a" target="_blank">vraie image</a> étant moins sexy, mais il y aura certainement bientôt une image de l&#8217;anneau complet)</p>
<div class="wp-caption aligncenter" style="width: 526px"><a href="http://science.nasa.gov/headlines/y2009/07oct_giantring.htm"><img class=" " src="http://science.nasa.gov/headlines/y2009/images/giantring/392150main_spitzer20091006-516.jpg" alt="vue dartiste de lanneau de Saturne observé dans linfrarouge par Spitzer" width="516" height="413" /></a><p class="wp-caption-text">vue d&#39;artiste de l&#39;anneau de Saturne observé dans l&#39;infrarouge par Spitzer</p></div>
<p style="text-align:left;">Dans l&#8217;ultraviolet, ce sont principalement <a href="http://fr.wikipedia.org/wiki/GALEX" target="_blank">Galex </a>et <a href="http://fr.wikipedia.org/wiki/SWIFT_%28t%C3%A9lescope_spatial%29" target="_blank">Swift </a>qui scrutent le ciel. Swift a produit une <a href="http://www.nasa.gov/mission_pages/swift/bursts/uv_andromeda.html" target="_blank">magnifique image de la galaxie d&#8217;Andromède</a> (M31) dans laquelle on peut distinguer 20&#8242;000 sources, principalement de jeunes étoiles. Admirez ça :</p>
<p style="text-align:center;"><span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/HWxBTHVhc3I&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' /><param name='allowfullscreen' value='true' /><param name='wmode' value='transparent' /><embed src='http://www.youtube.com/v/HWxBTHVhc3I&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' type='application/x-shockwave-flash' allowfullscreen='true' width='425' height='350' wmode='transparent'></embed></object></span></p>
<p style="text-align:left;"><a href="http://fr.wikipedia.org/wiki/Chandra_%28t%C3%A9lescope_spatial%29" target="_blank">Chandra </a>est le télescope spatial à rayons X  le plus productif actuellement. Les rayons X sont produits par des phénomènes très violents, souvent liés aux trous noirs. Récemment Chandra a produit la partie orange de cette image de NGC 6240 :</p>
<div class="wp-caption aligncenter" style="width: 442px"><a href="http://chandra.harvard.edu/photo/2009/ngc6240/" target="_blank"><img class=" " src="http://chandra.harvard.edu/photo/2009/ngc6240/ngc6240.jpg" alt="centre de la galaxie NGC 6240, visible en blanc, rayons X en orange (clqiuer pour plus dinfos)" width="432" height="276" /></a><p class="wp-caption-text">centre de la galaxie NGC 6240, visible en blanc, rayons X en orange (clqiuer pour plus d&#39;infos)</p></div>
<p>On distingue au centre deux sources très lumineuses. Il s&#8217;agit de deux trous noirs supermassifs qui furent les centres de<a href="http://drgoulu.com/2008/04/25/un-festival-de-galaxies/" target="_blank"> deux galaxies qui ont fusionné</a> pour former NGC 6240. Ils se tournent autour en irradiant d&#8217;énergie les environs, baignant une bonne partie de la galaxie de rayons X. Dans quelques dizaines de millions d&#8217;années, lorsque les deux trous noirs fusionneront , ce sera <a href="http://drgoulu.com/2008/04/18/ca-cest-du-trou-noir-du-vrai/">l&#8217;Apocalypse selon OJ 287</a>.</p>
<p>Ce phénomène produira a coup sur une flambée de rayons gamma, la &#8220;lumière&#8221; la plus violente que l&#8217;on puisse imaginer. <a href="http://fr.wikipedia.org/wiki/Fermi_Gamma-ray_Space_Telescope" target="_blank">Fermi </a>(anciennement nommé GLAST) et<a href="http://fr.wikipedia.org/wiki/SWIFT_%28t%C3%A9lescope_spatial%29" target="_blank"> Swift</a> sont les télescopes dédiés à l&#8217;observation des <a href="http://drgoulu.com/2008/03/21/sursaut-gamma-la-folie-celeste/" target="_blank">sursauts gamma</a>, ces événements si violents qu&#8217;ils ont été confondus avec des explosions nucléaires sur Terre par les premiers satellites de surveillance militaires. Ils détectent environ <a href="http://grb.sonoma.edu/" target="_blank">un &#8220;Gamma Ray Burst&#8221; par jour</a>, et on ne sait toujours pas exactement ce qui peut en provoquer autant.</p>
<p style="text-align:left;">Il ne faudrait pas pour autant oublier les radiotélescopes. Après <a href="http://fr.wikipedia.org/wiki/Radiot%C3%A9lescope_d%27Arecibo" target="_blank">Arecibo</a> qui ne captait que des signaux, le <a href="http://fr.wikipedia.org/wiki/Very_Large_Array" target="_blank">Very Large Array</a> (VLA) et  le <a href="http://fr.wikipedia.org/wiki/VLBA" target="_blank">Very Long Baseline Array</a> (VLBA) fournissent désormais des images &#8220;radio&#8221; avec une résolution comparable aux télescopes optiques. En combinaison avec d&#8217;autres instruments, la <a href="http://fr.wikipedia.org/wiki/Radioastronomie" target="_blank">radioastronomie </a>permet de mieux comprendre des phénomènes aussi titanesques que les <a href="http://drgoulu.com/2008/05/03/le-jets-des-trous-noirs/" target="_blank">jets des trous noirs</a>:</p>

Spitzer), който позволява на учените да изследват вселената в инфрачервения спектър, наскоро направи поредното си откритие. Обсерваторията е открила още един пръстен на планетата Сатурн. Това е 8-мият пръстен на 6-тата планета в нашата Слънчева система и е съставен от много малки частици, които не отразяват видимата светлина. Това е и причината той да бъде открит чак сега, благодарение на инфрачервените сензори на Спицър. Новият пръстен е огромен, колкото 1 милиард планети с размера на Земята.</p>

<p>На пръв поглед откритието не изглежда толкова значително, но всъщност показва, че имаме да учим още много за Космоса. Изучаването на Вселената обаче е огромно предизвикателство и докато не изобретим двигатели, с които да пътуваме поне със светлинна скорост, не виждам как ще успеем да научим много.</p>

<p>В момента голяма част от знанията ни идват благодарение на изведените в Космоса телескопи, известни като &#8220;Великите Обсерватории&#8221; на NASA. Най-известната от тях е телескопът <a href="http://techstation.wordpress.com/tag/%D1%85%D1%8A%D0%B1%D1%8A%D0%BB/" target="_blank">Хъбъл</a>, който е изведен в орбита около Земята преди 19 години и до днес продължава да прави своите невероятни открития. Следващият е Спицър &#8211; инфрачервена космическа обсерватория, изстреляна през 2003 година. В момента тя се намира в орбита около Слънцето, с изчерпан запас от хелий, но продължава да функционира. Следват обсерваториите <a href="http://bg.wikipedia.org/wiki/%D0%A7%D0%B0%D0%BD%D0%B4%D1%80%D0%B0" target="_blank">Чандра Рентгенова Обсерватория</a> и Комптън Гама Лъчева Обсерватория, които гледат Вселената в инфрачервения спектър и ни показват неща, които иначе няма как да видим.</p>
<p>Тъй като жизненият цикъл на Хъбъл наближава своя край, NASA планира от доста време негов наследник. Това е космическият телескоп Джеймс Уеб. Той ще има по-голямо огледало и ще обикаля земята в по-далечна орбита от тази на Хъбъл, отвъд Луната. Джеймс Уеб ще ни позволи да вникнем много по-надалеч и чрез него ще търсим истината за раждането на Вселената &#8211; Големия взрив.</p>
<p><em>Забележка: В орбита има и други изведени телескопи, но техния предвиден живот е много кратък, затова и не съм ги отбелязал в този пост.</em></p>

<description><![CDATA[Every now and again I remember that this is supposed to be some sort of science blog. This happened ]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>Every now and again I remember that this is supposed to be some sort of science blog. This happened again this morning after three hours of meetings with my undergraduate project students. Dealing with questions about simulating the cosmic microwave background, measuring the bending of light during an eclipse, and how to do QCD calculations on a lattice reminded me that I&#8217;m supposed to know something about stuff like that.</p>
<p>Anyway, looking for something to post about while I eat my lunchtime sandwich, I turned to the estimable <a href="http://arxiv.org/">arXiv</a> and turned to the section marked <a href="http://arxiv.org/archive/astro-ph">astro-ph</a>, and to the <a href="http://arxiv.org/list/astro-ph/new">new submissions</a> category, for inspiration.</p>
<p>I&#8217;m one of the old-fashioned types who still gets an email every day of the new submissions. In the old days there were only a few, but today&#8217;s new submissions were 77 in number, only about half-a-dozen of which seemed directly relevant to things I&#8217;m interested in. It&#8217;s always a bit of a struggle keeping up and I often miss important things. There&#8217;s no way I can read as widely around my own field as I would like to, or as I used to in the past, but that&#8217;s the information revolution for you&#8230;</p>
<p>Anyway, the thing that leapt out at me first was an <a href="http://arxiv.org/abs/0910.1317">interesting paper by Dikarev et al</a> (accepted for publication in the Astrophysical Journal) that speculates about the possibility that dust grains in the solar system might be producing emission that messes up measurements of the <a href="http://en.wikipedia.org/wiki/Cosmic_microwave_background_radiation">cosmic microwave background</a>, thus possibly causing the curious <a href="http://en.wordpress.com/tag/cosmic-anomalies/">cosmic anomalies</a> seen by WMAP I&#8217;ve blogged about on more than one previous occasion.</p>
<p>Their abstract reads:</p>
<blockquote><p>Analyses of the cosmic microwave background (CMB) radiation maps made by the Wilkinson Microwave Anisotropy Probe (WMAP) have revealed anomalies not predicted by the standard inflationary cosmology. In particular, the power of the quadrupole moment of the CMB fluctuations is remarkably low, and the quadrupole and octopole moments are aligned mutually and with the geometry of the Solar system. It has been suggested in the literature that microwave sky pollution by an unidentified dust cloud in the vicinity of the Solar system may be the cause for these anomalies. In this paper, we simulate the thermal emission by clouds of spherical homogeneous particles of several materials. Spectral constraints from the WMAP multi-wavelength data and earlier infrared observations on the hypothetical dust cloud are used to determine the dust cloud&#8217;s physical characteristics. In order for its emissivity to demonstrate a flat, CMB-like wavelength dependence over the WMAP wavelengths (3 through 14 mm), and to be invisible in the infrared light, its particles must be macroscopic. Silicate spheres from several millimetres in size and carbonaceous particles an order of magnitude smaller will suffice. According to our estimates of the abundance of such particles in the Zodiacal cloud and trans-neptunian belt, yielding the optical depths of the order of 1E-7 for each cloud, the Solar-system dust can well contribute 10 microKelvin (within an order of magnitude) in the microwaves. This is not only intriguingly close to the magnitude of the anomalies (about 30 microKelvin), but also alarmingly above the presently believed magnitude of systematic biases of the WMAP results (below 5 microKelvin) and, to an even greater degree, of the future missions with higher sensitivities, e.g. PLANCK.</p></blockquote>
<p>I haven&#8217;t read the paper in detail yet, but will definitely do so. In the meantime I&#8217;d be interested to hear the reaction to this claim from dusty experts!</p>
<p>Of course we know there is dust in the solar system, and were reminded of this in spectacular style earlier this week by the discovery (by the <a href="http://www.nasa.gov/mission_pages/spitzer/main/index.html">Spitzer telescope</a>) of an enormous new ring around Saturn.</p>
<p>That tenuous link gives me an excuse to include a gratuitous pretty picture:</p>

<p>It may look impressive, but I hope things like that are not messing up the CMB. Has anyone got a vacuum cleaner?</p>

<p>Un nuevo anillo de dimensiones colosales y muy tenue ha sido localizado alrededor de Saturno. Se trata de un círculo de polvo que se extiende desde seis millones de kilómetros de distancia del planeta y tiene una extensión de otros 12 millones de kilómetros, hasta 50 veces más allá de los anillos principales. La nueva banda de polvo y hielo ha sido localizada por el telescopio espacial Spitzer, de la NASA. Los científicos que publican el trabajo en la revista Nature creen que el anillo probablemente está compuesto de restos desprendidos de la luna Febe, que orbita Saturno dentro del anillo, tras pequeños impactos de cometas.</p>
<p>La escala del nuevo anillo es asombrosa. No se ha visto nada similar en todo el Sistema Solar. El círculo exterior más visible de entre las famosas bandas de hielo y polvo de Saturno es el anillo E, que abarca la órbita de la luna Encelado, que rodea al planeta a una distancia de 240.000 kilómetros.</p>
<p>El nuevo anillo no es sólo mucho más ancho y externo, también es más alto y está inclinado un ángulo de 27 grados respecto al plano en el que se presentan el resto de anillos.</p>
<p>El descubrimiento supondría la resolución de uno de los grandes misterios de la ciencia planetaria: por qué la luna Jápeto, que va en dirección contraria al nuevo anillo y a Febe, como la mayoría de las demás lunas de Saturno, tiene una apariencia en dos tonos, con una cara del satélite mucho más oscura que la otra. Se cree que la presión de la luz solar empuja a los granos más minúsculos del anillo hacia la órbita de Jápeto, que rodea Saturno a una distancia de 3,5 millones de kilómetros. &#8220;Las partículas se estrellan en Jápeto como insectos en un parabrisas&#8221;, señala Anne Verbiscer, de la Universidad de Virginia (EE UU). Las observaciones del material que cubre la cara oscura de esta luna indican que tiene una composición similar a la de la superficie de Febe.</p>
<p>Los científicos ya sospechaban de la existencia de este anillo gigantesco y el telescopio de infrarrojos Spitzer, en órbita del Sol, lo confirmó en mayo pasado, antes de que se le acabara el líquido refrigerante, aunque se ha presentado ahora. &#8220;Las partículas son muy, muy pequeñas, así el anillo es muy, muy tenue; de hecho, si te colocases dentro de él, ni siquiera lo advertirías&#8221;, ha señalado Verbiscer. Es tan poco denso que los científicos han calculado que si todo el material fuera recogido cabría en un solo cráter de Febe, que tiene 220 kilómetros de diámetro.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p> </p>
<div id="attachment_1140" class="wp-caption aligncenter" style="width: 397px"><a href="http://lightsinthedark.wordpress.com/files/2009/10/392164main_d-saturnringimageplain.jpg"><img class="size-full wp-image-1140" title="Saturn's Largest Ring" src="http://lightsinthedark.wordpress.com/files/2009/10/392164main_d-saturnringimageplain.jpg" alt="Newly discovered ring around Saturn" width="387" height="727" /></a><p class="wp-caption-text">Newly discovered ring around Saturn</p></div>
<p>The bright band in this image is a cross-section of a massive <a href="http://www.jpl.nasa.gov/news/news.cfm?release=2009-150" target="_blank">new ring discovered around Saturn</a>, a cold, diffuse and incredibly thick band of material orbiting the planet 3.7 million miles out&#8230;..much farther out than any of the other rings and farther away even than most of Saturn&#8217;s moons.</p>
<p>The ring is so thick, 20 Saturns could be stacked top to bottom in its vertical height.</p>
<p>Effectively invisible due to its diffuse nature and low reflectivity in the dim light at Saturn&#8217;s distance from the sun, the ring was discovered by the <a href="http://www.nasa.gov/mission_pages/spitzer/main/index.html" target="_blank">Spitzer Space Telescope</a>, which is sensitive to infrared light emitted by heat. Although cold – minus 316º F  – the ring particles still emit enough heat to be detectable by Spitzer&#8217;s sensitive instruments.</p>
<blockquote><p>&#8220;The particles are so far apart that if you were to stand in the ring, you wouldn&#8217;t even know it.&#8221;</p>
<p>– Anne Verbiscer, astronomer at the University of Virginia</p></blockquote>
<p>Saturn&#8217;s moon <a href="http://saturn.jpl.nasa.gov/photos/imagedetails/index.cfm?imageId=898" target="_blank">Phoebe</a> orbits within this newly-discovered disc. The dark, battered moon, orbiting Saturn in a retrograde orbit, is most likely a captured object from the outer depths of the solar system. Collisions between it and ill-fated comets over the millennia may be the source of this ring&#8217;s material.</p>
<div id="attachment_1141" class="wp-caption alignright" style="width: 106px"><a href="http://lightsinthedark.wordpress.com/files/2009/10/iapetus.jpg"><img class="size-thumbnail wp-image-1141" title="iapetus" src="http://lightsinthedark.wordpress.com/files/2009/10/iapetus.jpg?w=96" alt="Iapetus" width="96" height="96" /></a><p class="wp-caption-text">Iapetus</p></div>
<p>It&#8217;s also suspected that this ring may also be the cause of the mysterious dark coating over one-half of Iapetus&#8217; surface. Scientists have been hypothesizing about the reason behind the moon&#8217;s two-toned coloration for decades. It&#8217;s now looking like it may be the result of dark material from this hazy ring being drawn into nearby Iapetus&#8217; orbit and striking the leading side of the moon. </p>
<p>Iapetus orbits Saturn in a more common prograde direction, as opposed to both Phoebe and the new ring. The material would strike it from the opposite direction, like &#8220;bugs on a windshield&#8221;.</p>
<p>The discovery of this huge ring was made last May, before the Spitzer telescope ran out of its coolant.</p>

<p style="text-align:justify;"><strong>Il telescopio spaziale della Nasa, Spitzer, ha scoperto il più grande anello di Staturno</strong> mai osservato prima di oggi. Il laboratorio californiano ha annunciato che l&#8217;anello si situa alla periferia del sistema di Saturno, in un&#8217;orbita inclinata di 27 gradi rispetto al principale anello conosciuto. Saturno ne conta sette principali.</p>
<p style="text-align:justify;"><strong>Il nuovo anello è composto di ghiaccio e di polvere allo stato di particelle</strong>, in una atmosfera di -157 gradi Celsius. L&#8217;anello è molto esteso e non è facile vederlo, perché non riflette la luce visibile. Il telescopio Spitzer ha potuto localizzarlo grazie ai raggi infrarossi. In effetti, malgrado il suo intenso freddo, l&#8217;anello brilla sotto l&#8217;effetto di radiazioni termiche. La massa dell&#8217;anello comincia a circa sei milioni di chilometri dal pianeta e si estende su 11,9 milioni di chilometri.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Desde hace tiempo los astrónomos sospechaban que el que <em>Jápeto</em> tenga una mitad clara y otra oscura tiene que ver con material que se desprende de <em>Febe</em>, otra luna de Saturno que gira en el sentido contrario a la primera, material que se habría estampado contra <em>Jápeto</em> durante millones de años haciendo que una de sus mitades se vea más oscura, un poco como los insectos que chocan contra el parabrisas de un coche.</p>
<p>Para intentar comprobar esto, en el pasado mes de mayo, apuntaron el telescopio espacial <strong><em>Spitzer</em></strong> a esa zona del espacio y en efecto descubrieron que había polvo flotando en el espacio, pero mucho más del que se esperaban.</p>
<p><img class="alignleft size-full wp-image-443" title="SpitserNuevoAnilloSaturnoConcepcionArtistica" src="http://aulageek.wordpress.com/files/2009/10/spitsernuevoanillosaturnoconcepcionartistica1.jpg" alt="SpitserNuevoAnilloSaturnoConcepcionArtistica" width="400" height="321" />De hecho lo que descubrieron fue un nuevo anillo de Saturno de tamaño considerable que empieza a unos seis millones de kilómetros de este y que se extiende por otros 12 millones de kilómetros, con un grosor nada desdeñable de unos 2,5 millones de kilómetros. Harían falta unos mil millones de Tierras para rellenarlo: <strong>NASA Space Telescope Discovers Largest Ring Around Saturn.</strong></p>
<p>Si lo pudiéramos ver, tendría el ancho de dos Lunas, una a cada lado de Saturno.</p>
<p>Si este anillo, a pesar de su tamaño, no ha sido detectado antes es porque las partículas que lo componen se hallan muy dispersas -según los científicos que lo han descubierto podrías estar en medio del anillo sin darte cuenta de ello- y porque apenas reflejan la luz visible, aunque en el infrarrojo el <em><strong>Spitzer</strong></em> no ha tenido problemas para verlo dada su temperatura de unos 80 kelvin (unos 193 grados centígrados bajo cero).</p>
