Description

M31, the Andromeda Galaxy presented in HaLRGB. The red regions highlight the Ha emission nebulae. Andromeda is 2.5 million light years from earth and 220, 000 light years in size. Traveling at 68 miles per second it will collide with our galaxy in 4 billion years. Though, it is expected (statistically) there won't be any star collisions when the galaxies merge.

Enjoy!
