Astronomers from Cardiff University, UK, have employed the Combined Array for Research in Millimeter-wave Astronomy (CARMA) to explore the nearby Andromeda galaxy. Results of the observational campaign, published December ...
Astronomers know that mergers play a huge role in galaxy growth. Right now, the Milky Way is slowly consuming the Large and Small Magellanic Clouds. The evidence is a stream of gas called the Magellanic Stream that's about ...
