Today’s paper takes you back to the time when anisotropies in the Cosmic Microwave Background first shaped Observational Cosmology into the field it is today.
In 1972 astronomers witnessed the first full galaxy collision, not by looking up at the sky but by peering at a small screen in a very large box. The methods and implications are enshrined in modern astrophysics, but it is the results themselves that still truly amaze, stunning simple images of galaxies, playfully strewn and joyfully picked apart. A full exploration of a galaxy of a scale not matched before or since.
Today we’re talking about the history of gamma-ray astrophysics, starting with a very important observation from the late 1980s
Today’s ‘beyond’ bite takes you back to 2000, when a new telescope meant to survey the night sky takes the astrophysics community by storm.
Throw a bunch of different planetary systems into your supercomputer and let them simmer for a hundred million years. Eventually, they’ll all be more alike than they started.
A classic paper on dark matter is brought to ‘light’ in this bite, discussing a discovery that provides one of the best evidences we have for non-baryonic matter in the universe.
