NASA's Hubble Space Telescope has captured a stunning new image of, NGC 474, an elliptical galaxy that's 2.5 times larger than our Milky Way.

The Hubble Space Telescope has peered deep into the heart of our Milky Way Galaxy, revealing a tapestry of more than half a million stars, NASA announced Thursday.

A galaxy similar to our own Milky Way, the barred spiral NGC 1073, is the subject of the Hubble Space Telescope's latest portrait.

Astronomers have pieced together a detailed picture of how our Milky Way galaxy came together, using Hubble Space Telescope photos of 400 similar galaxies at various stages of evolution.

However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31).

Hubble went on to discover the expanding universe where galaxies are rushing away from us, but it has long been known that M31 is moving toward the Milky Way at about 250,000 mph (400,000 km/h).

Hubble wrote about his discovery to Harlow Shapley, who had argued that the Milky Way encompassed the entire universe. “Here is the letter that destroyed my universe,” Shapley remarked .
