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.

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.

Identifying the handful of far-flung Milky Way residents was no picnic, as each Hubble image contained more than 100,000 stars. [ Stunning Photos of Our Milky Way Galaxy ] ...

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at ...

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).

Scientists previously predicted the pair of galaxies would merge in about five billion years. Now, research suggests that ...

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 .
