2.5 Billion Pixel Image of Galaxy Shot by Hubble

The Andromeda galaxy holds over 1 trillion stars and has been a key to unlocking the secrets of the universe. Thanks to NASA’s Hubble Space Telescope, we’re now seeing Andromeda in stunning new detail, revealing its dynamic history and unique structure.

Recent Hubble surveys mapped the galaxy’s entire disk—an effort spanning a decade and over 1,000 orbits—showing everything from young stars to remnants of past galactic collisions.
