Science Scanner: Monster Galaxy; Mars Missions On Vacation

June 8, 2015

Monster Galaxy Found Near Edge of Universe A group of researchers imaged a “monstrous galaxy” – SDP.81, located some 11.7 billion light-years from Earth, using the Atacama Large Millimeter/sub-millimeter Array (ALMA) in Chile and a natural magnification method called “gravitational lensing.” The researchers used the gravity of a massive galaxy 3.4 billion light-years away to […]

Global Precipitation Changes Linked to Human-induced Climate Change

November 12, 2013
