Monster Galaxy Churns Out 1,000 Times As Many Stars As Our Own

About 10 years ago, astronomers catalogued a galaxy 12.4 billion light years away called COSMOS-AzTEC-1, a giant “monster galaxy” believed to be an ancestor of massive modern galaxies like ours. Galaxies go through an evolutionary process, changing from disordered masses of gasses to star-filled stunners like our own beautiful Milky Way. Because researchers are viewing AzTEC-1 at the early stages of its existence, they expected that it would still be a little chaotic. But Sarah Lewin at Space.com reports the galaxy might be ahead of the curve: the monster galaxy is producing 1,000 times as many stars as the Milky Way.

Supermassive Black Hole Stretches Starlight, Proving Einstein Right Again

Albert Einstein’s theory of general relativity is magnificent. For a hundred years, it has consistently predicted all sorts of wacky phenomena scientists have later observed throughout space. One international team is now announcing that a 26-year-long observation campaign has once again confirmed the theory. Continue reading Supermassive Black Hole Stretches Starlight, Proving Einstein Right Again

Landmark Cosmic Observation Provides Tantalizing Hints of Dark Matter

Today, scientists announced that they’d seen evidence of a long-sought signal from the first stars. This slight change to some ambient radio waves could herald the first step in a new kind of astronomy. But maybe, just maybe, it’s also evidence of dark matter interacting with regular matter in the ancient universe. Continue reading Landmark Cosmic Observation Provides Tantalizing Hints of Dark Matter
