One of the most incredible things about black holes is how much bigger they are than almost anything else out there. Now, a new image taken at the Atacama Large Millimeter/submillimeter Array (ALMA) Observatory shows that we’ve been totally wrong about how they manage to grow so large.
This rainbow splatter might not look like the beautiful images of galaxies you’re used to seeing, but it’s actually rather special. It’s the highest angular resolution astronomical image ever captured, and it shows a jet of matter erupting out of a black hole 900 million light years away.
Black holes are some of the strangest objects in the universe. But, just as impenetrable a mystery? The heavy cloud cover encircling some black holes. Now, for the first time, researchers say they’ve managed to get a glimpse inside of one of those clouds. And what they found has some serious implications for our most…
Two theories, from the always knowledgable Kurz Gesagt: you die a quick death or you die a very quick death. No one knows for sure but you probably don’t want to be the first person to find out. If you do, you’ll notice that time moves slower inside the black hole. But once you’re in though, you can only go in one…
“Here be dragons” was a phrase once used on ancient maps, often accompanied by mythical sketches, to highlight an unexplored or potentially dangerous area. Astronomers might want to borrow this warning to label the centre of galaxies, which contain supermassive black holes.
What you’re seeing is V404 Cygni, a binary system consisting of a star and a black hole, some 7800 light-years away. It has lain quiet for the last 25 years, but a week ago, NASA’s Swift satellite noticed a burst of new activity.
Between rainbows, rings, and sharp, hard lines, it’s difficult to not clap my hands in glee while unpacking the levels of awesome crammed in this X-ray image of Circinus X-1. The beautiful bullseye light echoes hint this neutron star is farther, brighter, and more like a black hole than we thought.
This woman totally seems like she has harnessed the power of a black hole and can suck up all the light and everything around her. But it's just a nice little camera trick showing swinging burning steel wool in reverse. The light flies to her as she twists and turn but in reality, it's just being flung away. Still…
The Royal Observatory of Greenwich, England, has crafted three simple animations to explain three very complex things: What's inside a black hole, how do we know the age of the sun—did you know the Sun weighs 4,000 trillion trillion hippopotamuses?—and how big is the Universe.
According to physicists, there are three, er, two and a half different theories on how a person would die if they got sucked in by a black hole: stretched like a spaghetti noodle, burnt like a toast and maybe even scrambled. Nova PBS explains that if the argument on how people would die if swallowed by a black hole…
Scientists are proposing a radical new way of think about how the universe began. In a new imagining of the Big Bang theory, they think it could have been the result of a four-dimensional star collapsing in on itself to form a black hole, which then proceeded to spew its guts out and, kindly, form our universe.
Stephen Hawking. Theoretical Physicist. Cosmologist. Smart guy. Beyond genius, actually. Hell, very probably the best brain that us humans have right now. But so much of his intelligence is hard to grasp for less wrinkled brains like us. This animation, made by The Guardian as part of its Made Simple series, breaks…
This might look like a strange microscopic image, or even an aerial view of a sprawling city late at night—but in fact it's what a 600-billion-billion-kilometre-wide section of the universe looks like.
Over 47 million light years away, in a galaxy called NGC 4845, there's one hungry black hole. In fact, scientists have watched in awe as, soon after it stirred from dormancy, it chomped away at a planet 30 times the mass of Jupiter.
This stunningly trippy object is W49B, a supernova remnant 26,000 light years away from Earth. It's just a thousand years old, which in cosmological terms is not even a heartbeat in the life of a human. It may also be the birth place of a newborn black hole, the youngest ever detected in the galaxy.
The black hole at the center of our galaxy isn't happy. In fact, it's spitting out its biggest X-ray flares ever, which are a hundred times more powerful than anything it's ever produced before.
Look at this star turned into a fire dragon by a single point of nothingness with the mass of three million suns—its body twisted and deformed as a black beast 2.7 billion light-years away devours it with infinite hunger.
If you thought space was a peaceful vacuum, think again: scientists have discovered the fastest winds ever observed on a stellar-mass black hole, and they reach an incredible 20 million mph.
This is exciting. If everything goes well, we may get the first-ever photo of a black hole really soon. A big number of astronomers are getting ready to achieve this feat using a global network of telescopes:
