The Andromeda galaxy is a colossal marvel in our sky, hosting over 1 trillion stars. Now, astronomers have used the Hubble Space Telescope to capture hundreds of detailed images of our vast galactic ...

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 ...

They identified a giant grand-design spiral galaxy, named Zhúlóng, which could well be the most distant ever observed. This galaxy, located at a photometric redshift of about 5.2, has a mass ...

"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 Milky Way is our home galaxy home to 100-400 billion stars (no one is quite sure how many). It’s a spiral galaxy estimated to be about 13.6 billion years old. It's 100,000 light-years across.
