Andromeda galaxy Amazing Andromeda
Our galactic neighbor, the Andromeda galaxy, is seen in ultraviolet and infrared in this combined image from NASA's Galaxy Evolution Explorer and Spitzer Space Telescope. Young, hot, high-mass stars are shown in blue, while populations of relatively older stars are green dots. The bright yellow spot at the galaxy's center depicts a particularly dense population of old stars. Swaths of red indicate cool, dusty regions where stars are forming.
