About 100 years after astronomer Edwin Hubble's discovered the "magnificent" spiral nebula, the Hubble Space Telescope and NASA scientists have produced the most comprehensive survey of the Andromeda galaxy, or Messier 31. The Andromeda galaxy is approximately 2.5 million light-years away from the Milky Way.

"Photographing Andromeda was a herculean task because the galaxy is a much bigger target on the sky than the galaxies Hubble routinely observes, which are often billions of light-

In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way—the magnificent Andromeda galaxy (Messier 31).

NASA's Hubble Space Telescope has provided unprecedented details about the Andromeda galaxy's history and characteristics. Andromeda, a galaxy 2.5 mil

The Andromeda galaxy, our nearest major galactic neighbor and one of the most iconic objects in the night sky, has captivated the imaginations of astronomers and stargazers for centuries. Known as Messier 31,
