Hubble’s Photomosaic of Andromeda Galaxy Unveils Hundreds of Millions of Stars

The Andromeda galaxy is seen almost edge-on, tilted by 77 degrees relative to Earth’s view; interesting regions include: (a) clusters of bright blue stars embedded within the galaxy, background galaxies seen much farther away, and photo-bombing by a couple bright foreground stars that are actually inside our Milky Way; (b) NGC 206 is the most conspicuous star cloud in Andromeda; (c) a young cluster of blue newborn stars; (d) the satellite galaxy M32, that may be the residual core of a galaxy that once collided with the Andromeda galaxy; (e) dark dust lanes across myriad stars.

A century ago, the American astronomer Edwin Hubble first established that this so-called ‘spiral nebula’ was approximately 2.5 million light years away from our Milky Way Galaxy. Now, the NASA/ESA Hubble Space Telescope has accomplished the most comprehensive survey of the Andromeda galaxy. It took more than 10 years to collect data for this colorful portrait, which captures the glow of 200 million stars, and was created from more than 600 snapshots. This...
