Galaxy Megamergers 1.4 – 1.5 Billion Years after the Big Bang

April 26, 2018

Two teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder Experiment (APEX), in Chile, to observe dense concentrations of so-called “starburst” galaxies. With these galaxies packing together so closely, the scientific teams realized that they were getting ready to violently collide and merge with each other, which would eventually […]

Astronomers Find Massive Star Making Galaxy Cluster

September 12, 2015

Astronomers have discovered a distant and massive galaxy cluster with a gigantic and prolific galaxy at its heart that’s pumping out hundreds of stars each year. The galaxy cluster is named SpARCS 1049+56 and is located about 9.8 billion light years from Earth in the Ursa Major constellation. Galaxy clusters are areas of the universe […]
