Nebulae tend to be stunning by their very nature, but the Twin Jet Nebula might just take the cake. The Hubble Space Telescope team has captured an updated image of the dying binary star system (the last shot was from 1997), and its namesake twin jets of ejecting gas are unfurling like the irides...

While the Voyager 1 probe, launched in 1977, cruises into interstellar space (the farthest man-made object from Earth) and missions like New Horizons capture snaps from the outskirts of the solar system, we've been keeping the heavy hitters close to home. Massive space telescopes that scan the cos...

A small minority of enormous stars explode in a fiery supernova after they run out of fuel and collapse. Regular stars die less spectacularly, but the remnants can still be gorgeous. Case in point is NGC 6153, a nebula about 4,000 light-years from Earth. The ethereal blueish, ellipse-shaped cloud...

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...

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 cluste...

Today, 25 years ago, Hubble finally left Earth aboard the Space Shuttle Discovery after decades of planning and development. Its journey was fraught with problems and delays, but it ultimately rose above it all to bring us groundbreaking scientific discoveries and historic photos of planets, galax...

Like it or not, all galaxies will eventually die. But have you wondered just how they meet their grisly ends? Researchers now have a good idea. They've studied 22 very large elliptical galaxies about 10 billion years old, and have discovered that these celestial bodies die from the inside out. The...

Scientists typically believe that dark matter, for all of its mystery, behaves in a simple way: if one clump encounters another, the two interact solely through gravity. However, researchers using both Hubble and the Very Large Telescope have published findings which suggest that there's more inv...

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...

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...

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...
