How Do Astronomers Use Light to Probe Dark Matter?

Looking throughout our universe, we see many fascinating objects and diverse phenomena. Observing over a range of wavelengths and distances, astronomers around the world have detected various planets, some possibly supporting life, as well as twinkling stars, evolving nebulae and clouds of gas and dust, exploding novae, spiraling and rotating galaxies, some colliding with each other, in addition to quasars, blazars, pulsars, comets, and other exotic things. 1,141 more words

Fifty years of cosmic microwave background

Discovered in 1965, the cosmic microwave background (CMB) is the most ancient light record in the history of the Universe. Despite being detected as a “noise” across the sky, it did not take long for scientists to realise that this radiation is an incredibly rich source of information about the history of the cosmos, setting them on a search for more and more details in this early cosmic signal. 1,668 more words
