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 ...

Astronomers witness David versus Goliath fight between galaxies

Astronomers have witnessed, in the finest detail yet, a brutal David-vs-Goliath fight between two nearby galaxies that are tearing chunks from each other and flinging them into the gaseous Magellanic Stream, a cosmic river ...

Astronomers witness slow death of nearby galaxy

Astronomers from The Australian National University (ANU) and CSIRO have witnessed, in the finest detail ever, the slow death of a neighbouring dwarf galaxy, which is gradually losing its power to form stars.

Sextans: The smallest cannibal galaxy discovered until now

A team at the Instituto de Astrofísica de Canarias (IAC) has discovered a new case of galactic cannibalism in the neighbourhood of the Milky Way, which has caused the merging of two galaxies on the smallest scale so far ...

Pairs of small colliding galaxies may seed future stars

A pair of dwarf galaxies closely circling the Milky Way, the Large and Small Magellanic Clouds, were in the throes of merging into one when they fell into our galaxy. The duo is thought to hold enough gas to replenish half ...

A galactic test to clarify the existence of dark matter

Researchers at the University of Bonn and the University of California at Irvine used sophisticated computer simulations to devise a test that could answer a burning question in astrophysics: does dark matter actually exist? ...

How do you weigh a galaxy? Especially the one you're in?

A new technique for estimating the mass of galaxies promises more reliable results, especially when applied to large datasets generated by current and future surveys, according to a research team led by Ekta Patel at the ...
