For years, astronomers have struggled to understand the source of anomalous microwave emissions coming from various locations across the Milky Way galaxy. A recently concluded survey of the planet-forming disks around young stars suggests these strange transmissions are being produced by something rather…
On the way to its final orbit around Earth, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) has sailed by the moon and snapped its first picture of space. We’ve said several times that TESS would be able to look at 200,000 stars in the 300 light-years around the Earth—but maybe this new shot will…
Scientists have spotted 13-billion-year-old oxygen in a distant galaxy—a signal of stars forming during the universe’s earliest days.
Space is a chaotic, ever-changing place. But that’s not limited to exploding stars and colliding black holes. Even our own Milky Way galaxy could have recently received a massive jolt from which it is still recovering.
The European Space Agency’s Gaia spacecraft team has dropped its long-awaited trove of data about 1.7 billion stars. You can see a new visualization of all those stars in the Milky Way and nearby galaxies above, but you really need to zoom in to appreciate just how much stuff there is in the map. Yes, the specks are…
I can count on one hand the number of times I’ve seen the Little Dipper—the 2003 blackout, a family trip to the Grand Canyon, a camping trip, and a stargazing drive through Wisconsin cut short by the cold. I don’t remember ever seeing the faint band of the Milky Way. Growing up in New York’s suburbs, there just aren’t…
Around the same time our ancestors left Africa, a dim red dwarf star came to within 0.8 light-years of our Sun, marking the closest known flyby of a star to our Solar System. New research suggests Scholz’s Star, as it’s known, left traces of this interstellar encounter by perturbing some comets in the outer Oort Cloud.
It would be silly to think that scientists and astronomers have spotted all of the different kinds of weird things that exist in space. After all, we’re pretty sure the universe is mostly composed of dark matter and dark energy that we haven’t directly detected. But new research seems to imply that there are entirely…
The fine folks at NASA are sending a spacecraft to the Sun, and they want to send a little piece of you along with it. Here’s how to get your name on the ultimate “fry” list.
Neutron stars aren’t the twinkle-twinkle kind you typically see in the night sky. They’re stellar corpses, and incredibly dense sources of gravity, with perhaps 1.5 times the mass of the sun packed into an area less than a dozen miles across. Around 9,000 light years away from Earth, one neutron star seems to have…
When you sweep across the FM radio band, you don’t always hear music—mostly, you hear static. Lots of this ambient noise is actually garbled signals from throughout the Milky Way. If you had perhaps the most sensitive FM receiver on Earth, you might pick up the tiniest dip in volume: a signal that comes not from our…
Amateur astronomer Victor Buso was testing his camera-telescope setup in Argentina back in September 2016, pointing his Newtonian telescope at a spiral galaxy called NGC613. He collected light from the galaxy for the next hour and a half, taking short exposures to keep out the Santa Fe city lights. When he looked at…
Supernovae are already some of the brightest explosions in the universe—but there’s more mysterious type, called superluminous supernovae, that can shine a hundred times brighter than the usual ones. And on August 22, 2016, astronomers spotted one whose light traveled over 10 billion years to reach us.
Meet J0815+4729. If it were a Pokémon, it would be kind of like the Milky Way’s level-three Rattata.
By combining the power of four telescopes, an international team of astronomers has captured the most detailed image yet of a distant star—an observation that’s meshing well with pre-existing theories about the physical characteristics of giant stars.
Our Milky Way galaxy isn’t alone in this corner of space—it’s orbited by a few smaller dwarf galaxies, including the Large Magellanic Cloud. Inside that cloud is 30 Doradus (or the Tarantula Nebula), a “starburst” where stars are formed at a much higher rate than the surrounding area. And 30 Doradus has too many…
Sure, the restaurants are great, and you’ve probably got a decent sports team to root for. But the bright lights of a big city mean that at night you can rarely see more than a few stars in the sky, and these stunning timelapses of the galaxy overhead will make you realize the spectacular show you’re missing every…
550 light years from here is a star very much like our own, except that it has a strange habit of blinking out at irregular intervals. This erratic dimming, according to a new study, could be caused by clumps of orbiting gas and dust—the possible remnants of a planetary catastrophe.
Oops! Andromeda, our closest galactic neighbor, sits a measly 2.5 million light years away from Earth. Like the Milky Way, it’s a spiral galaxy packed with stars. Some of those stars orbit one another. That’s all good—but scientists have come to the realization that a particular light source, one assumed to be binary…
The Earth, the Sun, Andromeda galaxy, they’ve all been around for as long as you can remember and as long as humanity has been around. So when a new light suddenly shows up in the distance, it’s a weird occurrence. But a newly detected explosion could be one of the weirdest—and it’s not the only one.
