An international team of astronomers has discovered a huge expanse of space near the center of the Milky Way that’s devoid of young stars. This stellar desert extends for 8,000 light-years from the galactic core—and it hasn’t produced new stars for hundreds of millions of years.
Meet the Eye of Horus. It’s a newly discovered galaxy system that’s hiding something incredible in those fuzzy swirls of light circling it: a way of looking back into even further and older galaxies.
Here’s some knowledge that’ll make you feel like a microbe: Our Milky Way galaxy, a collection of hundreds of billions of stars and worlds, is but a tiny nucleus buried deep inside an enormous blob of million-degree gas that’s spinning at a rip-roaring 400,000 miles per hour.
The astronomical map you see here doesn’t depict stars, it shows galaxies—1.2 million of them, to be exact, a new record for astronomers. This extraordinary new 3D scan of the universe provides yet more evidence that a mysterious substance known as dark energy is likely causing the universe to expand at an…
A fairly ordinary-looking galaxy has been hiding a strange secret in plain sight. It is ten times larger than anyone thought (a whopping 718,000 light-years in diameter), plus it’s younger on the inside than it is on the out. Scientists think that it’s been stitched together from the pieces of several other…
The galaxy we’re zooming in on in the video above is LEDA 36252. It’s a tadpole galaxy 82 million lightyears away that has been steadily turning out new stars at an incredible rate for billions of years.
Researchers scanning the skies just got a big surprise. They spotted a humongous galaxy orbiting our own, where none had been seen before. It appeared, seemingly, out of nowhere.
Astronomers have just discovered one of the biggest black holes ever. Even more surprising, though, is where they found it—and the strange reason it got so big.
Looking at these spiral galaxies glowing brightly against the dark, it’s hard to imagine that they could be so easily missed—but they were right up until now, when an astronomical survey catalogued them as equal to the biggest and brightest galaxies ever seen.
Look deep into this photo and what you’ll see is something further away from you than you’ve ever glimpsed before.
The most powerful supercomputer simulation of the Universe is providing important insights into how matter is distributed across large scales. Surprisingly, a significant portion of matter resides outside of galaxies and in the cosmic voids that permeate the cosmos.
Astronomers at the International Centre for Radio Astronomy Research have discovered a galaxy with a rather remarkable feature—a massive plume of gas measuring 300,000 light-years across. That’s five times the length of the galaxy itself.
Astronomers just uncovered hundreds of hidden galaxies a mere 250 million light years away from Earth—well within our own galactic neighborhood. But how did they stay unknown for so long? The fault isn’t with them, it’s with our own Milky Way.
The Milky Way may have 13.6 billion years under its belt, but its stars range from newborns to ancients. Astronomers mapped how old the stars are, creating the first-ever age map of our galaxy—and this map could give us clues about how life in the Milky Way started.
What happens when two galaxies collide? Not complete and utter destruction, surprisingly, but a long, slow birth of a ‘new’ galaxy, which is what you can see happening in this image.
Astronomers in India have discovered a very unusual galaxy, and it’s dying. By now, in fact, it’s probably already dead.
Peering into the distant reaches of space is like turning back time. The bright red orbs at the center of this image are galaxies, as they existed 8.5 billion years ago in a faraway corner of the universe. Together, they form a cluster that grew to mind-boggling proportions long before the birth of our Solar System.
It’s time to update your desktop wallpaper, folks. The Hubble Space Telescope has captured some of the most remarkable images ever seen of the faintest and earliest known galaxies in the Universe.
According to Albert Einstein, the speed of light is an absolute constant beyond which nothing can move faster. So, how can galaxies be traveling faster than the speed of light if nothing is supposed to be able to break this cosmic speed limit?
Galactic collision! The Hubble Space Telescope captured this beautiful look at NGC 3921, a pair of disk galaxies in the late stages of merger. These galaxies, both about the same size, began merging 700 million years ago, as you can see from the distortions, including loops and tails, caused by the merge.
