Carte De Remerciements Andromède

Andromède est la Star Thank You Note. Two European Space Agency observatories 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 infrarouge wavelengths, and XMM-Newton shows dying stars shining X-rays into space. ESA’s Herschel and XMM-Newton space observatories targeted the Andromeda Galaxy, the nearest large spiral galaxy, which like our our own Milky Way contains several hundred billion stars. This is the most detailed far-infrarouge image of the Andromeda Galaxy ever taken and clearly shows that more are on their way. Dans this image, Herschel’s infrarouge image of the Andromeda Galaxy shows rings of dust that trace gaseous reservice where new stars are forming and XMM-Newton’s X-ray show stars approaching the ends of their lives. Both infrarouge and X-ray images convey information impossible to collect from the ground because these wavelengths are absorbbed by Earth's atmosphere.
