The first images of the stars that are forming now in the Andromeda Galaxy, the nearest to Earth, satellites have been captured by the European Space Agency (Esa) XMM-Newton and Herschel.
shooting in the days around Christmas, are the first images you see Andromeda X-ray and infrared, "coloring" of red, orange and yellow discs on its spiral. The same ones that appear in the observation optics of a blue that is becoming increasingly blurred and weak proceeding from the inside out.
In infrared images sent to Earth from the satellite Herschel hundreds of billions of stars in Andromeda appear very bright and, especially, are much more numerous than we imagined. In clouds of cold dust are real incubators of star formation, warning of a process that could take hundreds of millions of years.
So is the time needed before a star reaches an intensity that make it visible to conventional telescopes. For the first time, moreover, the Herschel Telescope images show that the dust in the galaxy are organized in five concentric rings.
