Celestial Eye     This new image of the Andromeda galaxy, taken by the European Space Agency's observatory Herschel and released January 28, reveal the temperature variations in the rings of dust swirling around our galactic neighbor.

Using a powerful infrared sensor, Herschel reveals that the center of the Andromeda galaxy hosts dust at warmer temperatures (colored blue) than the outer reaches of its rings, where dust hovering a few degrees above absolute zero reside.
