Some parts of space are a little more crowded than others. The Arches Cluster, located 25,000 light-years from Earth, is currently the densest known star cluster in the Milky Way. For comparison, if you measured the distance between our sun and its nearest star, and used that as a radius for a sec...

Peering through the voids of space is a lot like time travelling: the deeper we gaze into a seemingly endless Universe, the further back in time we can see. Now, a team of researchers led by astronomers from Yale University and UC Santa Cruz have announced that they've discovered the most distant ...

It's well established that runaway stars and planets are a cosmic reality, but runaway galaxies? Yes, amazingly enough, those exist. Scientists have discovered at least 11 galaxies moving so quickly (up to 6 million miles per hour) that they're escaping the gravitational tug of their host clusters...

NASA has long suspected that Jupiter's biggest moon, Ganymede, has a subsurface ocean, but that's hard to prove when it's in the outer solar system. Now, a team of scientists has found a way to provide evidence that an ocean does exist underneath its ice crust using the Hubble telescope. How? Well...

Gravity can play a lot of tricks with light, and we're not just talking about black holes. Take this recent Hubble Space Telescope discovery from UC Berkeley's Patrick Kelly, for example: those four lights are actually a distant supernova magnified and split into four images by the gravitational l...

The Hubble Space Telescope spots a lot of stars, but some of them are seemingly more eager to pose for snapshots than others. Take the star you see above, for example. That's V1331 Cyg, a young stellar object that's conveniently sending a jet of gas directly toward Hubble, providing a clear (and r...

NASA wants to know which among the most popular Hubble photos the internet likes the most, so it's pitting them against each other. To celebrate the telescope's 25th birthday in April, the agency has launched Hubble Mania, which is a space image smackdown of sorts, where the winner's determined by...

Does the image above look familiar? It's because the "Pillars of Creation" is one of the most iconic images captured by the Hubble Space Telescope -- except what you see in this post isn't the exact same photo taken in 1995. To celebrate the telescope's 25th birthday this year, the Hubble team has...
