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 ...

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 ...

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 ...

JWST has spotted a huge, ultramassive galaxy as it appeared 12.8 billion years ago, so intricately structured that it can only belong to the most spectacular category of galaxies: the grand design ...

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.

A newly released Hubble pic shows the galaxy LEDA 22057, where the supernova explosion occurred. The spiral galaxy's swirling mass centers around an oval-shaped core region with a white glow that ...
