WISE Photos of Heart and Soul

The first “Wide-field Infrared Survey Explorer (WISE) satellite has just completed its first survey of the entire sky viewable from Earth -- returning more than a million images that provide a zoomed-in look at celestial objects ranging from distant galaxies to asteroids.”

“Located about 6,000 light-years from Earth, the Heart and Soul nebulae in the constellation Cassiopeia form a vast star-forming complex that makes up part of an arm of the Milky Way Galaxy. The nebula to the right is the Heart, named after its resemblance to a human heart.”
