This mosaic image of Andromeda spiral galaxy -- showing explosive stars in its interior and cooler, dusty stars forming in its many rings -- combines observations from the Herschel Space Observatory taken in infrared light (the orange hues), and the XMM-Newton telescope captured in X-rays (the blues).
