Busy older stars outpace stellar youngsters, new study shows

The oldest stars in our Galaxy are also the busiest, moving more rapidly than their younger counterparts in and out of the disk of the Milky Way, according to new analysis carried out at the University of Birmingham.

Astronomers reveal true colors of evolving galactic beasts

Astronomers have identified a rare moment in the life of some of the universe's most energetic objects. Quasars were first observed 60 years ago, but their origins still remain a mystery. Now researchers at Durham University, ...

Image: Hubble traces a galaxy's outer reaches

Believe it or not, this long, luminous streak, speckled with bright blisters and pockets of material, is a spiral galaxy like our Milky Way. But how could that be? 

Holes in the Universe sharpen cosmic measurements

Regions of the Universe containing very few or no galaxies—known as voids—can help measure cosmic expansion with much greater precision than before, according to new research.

Elliptical galaxies shed new light on dark matter

In the 1930s, it was first noticed that the dynamics of astrophysical objects (galaxies, galaxy clusters and the universe itself) required an invisible and unknown form of mass, known now as dark matter. Strong mass discrepancies ...

Milky Way's neighbors pick up the pace

After slowly forming stars for the first few billion years of their lives, the Magellanic Clouds, near neighbors of our own Milky Way galaxy, have upped their game and are now forming new stars at a fast clip. This new insight ...
