The Andromeda Galaxy in Infrared and X-ray

This mosaic of the Andromeda spiral galaxy reveals explosive stars in its interior (X-rays in blues) and cooler, dusty stars forming in its many rings (infrared light seen in orange hues). The image is a combination of observations from the Herschel and XMM-Newton space observatories.
