Two ESA observatories have combined forces to show the Andromeda Galaxy in a new light. Herschel sees rings of star formation in this, the most detailed image of the Andromeda Galaxy ever taken at infrared wavelengths, and XMM-Newton shows dyi…
The prominent galaxy NGC 4666 in the centre of the picture is a starburst galaxy, about 80 million light-years from Earth, in which particularly intense star formation is taking place. The starburst is thought to be caused by gravitational intera…
Supermassive black holes, notorious for ripping apart and swallowing stars, might also help seed interstellar space with the elements necessary for life, such as hydrogen, carbon, oxygen and iron, scientists say. Using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton satellite, scientists at Penn State University and the Massachusetts Institute of Technology found evidence of high-speed winds blowing away copious amounts of gas from the cores of two quasar galaxies, which are thought to be powered by black holes.
