M32 – Companion Galaxy to Andromeda
This image of a large part of M32 was created from ultraviolet observations with Hubble and provides evidence that the ultraviolet light comes from a population of extremely hot, helium-burning stars at a late stage in their lives. Unlike the Sun, which burns hydrogen into helium, these old stars exhausted their central hydrogen long ago and now burn helium into heavier elements.
