Yale astronomers have announced the discovery of a galaxy with nine concentric rings—the most rings ever seen in a single ...

"Our finding offers key constraints for models of massive galaxy formation and the origin of spiral structures in the early universe." In the Universe around us today, galaxies come in a number of ...

Spiral galaxies have a thin ... we can estimate that there are about 50 billion galaxies in the universe. The 3-D model below will show you the structure of about 1,800 nearby galaxies.

Why it's so special: This image of a spiral galaxy taken by the Hubble Space Telescope is a portrait more than two decades in the making. Like most full-color images of space objects, it's a ...

But astronomers scrutinizing this particular Hubble image found the central galaxy actually sports a swirl of spiral arms seemingly unruffled by any such merger, raising new questions about what ...

"It's extremely rare and exciting to find a quasar-hosting galaxy with spiral arms and a black hole that is more than 400 million times the mass of the sun—which is pretty big—plus young jets ...

The Hubble Space Telescope has provided the most detailed survey of the Andromeda galaxy, revealing new clues about its ...

The magnificent Andromeda galaxy (Messier 31), stands out as the most important nearby stellar island to our Milky Way, and can be seen with the naked eye on a clear autumn night as “a faint ...

ESA’s decade-long Milky Way Gaia mapping mission still has tons of data to release over the next few years. Expect surprises.
