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.
Among the (many) mysteries surrounding the gigantic black holes that live at the center of galaxies is just how they managed to get so big, so fast. Finally, scientists have come up with an explanation for their improbably large existence.
Something strange is going on in a distant corner of our universe. About a dozen supermassive black holes are all shooting enormous jets of energy in roughly the same direction. It could be a cosmic coincidence—but some astronomers suspect there are larger forces at play.
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.
Two months ago, astronomers picked up and then pinpointed a location of a weird burst of radio waves from space, prompting heated debate about just what was sending them. Now, new data has finally revealed that source.
Earlier this week something happened to make Japan’s brand new black hole satellite suddenly, mysteriously lose all contact with Earth. Now, we have video of it spinning wildly in space—and JAXA has also received a few odd, new messages.
When the Laser Interferometer Gravitational Wave Observatory (LIGO) announced the first direct detection of gravitational waves, it was the culmination of 50 long years of hard work and perseverance in the face of skepticism. In her new book, Black Hole Blues, and Other Songs from Outer Space, astrophysicist Janna…
Last month, Japan launched a satellite it described as “essential” to unlocking the mysteries of the universe. This weekend, that $273 million satellite mysteriously disappeared, leaving behind only an ominous trail of debris and some cryptic messages.
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.
David Reitze, executive director of the LIGO Laboratory, took the podium at the National Press Building in Washington, DC, this morning, and said the words we’ve all been waiting on tenterhooks to hear: “We have discovered gravitational waves.” And a packed auditorium in Caltech’s Cahill building in Pasadena—where…
The rumors were true! This morning leaders of the Laser Interferometer Gravitational Wave Observatory (LIGO) announced the first direct detection of gravitational waves. In honor of this momentous discovery, the Perimeter Institute in Waterloo, Ontario, is hosting a live webcast today at 1pm EST: “Ripple Effects: A…
It’s official: we’ve directly detected gravitational waves. And unless you happen to be a PhD physicist, you probably have a few questions. Gizmodo is here to help.
Now you can watch as well as listen as world-renowned physicist Stephen Hawking expounds upon his latest ideas about the knotty black hole information paradox, playfully illustrated by chalkboard artist Andrew Park.
What’s this, you ask? Oh, it’s nothing. Just a supermassive black hole blasting a giant x-ray beam over a 300,000 light year-wide gulf of intergalactic space.
Black holes are some of the most powerful but difficult to comprehend objects in the universe, operating mysteriously and practically invisibly out of the reach of our sight. Until now, that is.
This is the Andromeda galaxy, our very own Milky Way’s next-door neighbor. It’s the best look we’ve ever managed to get at it—and there’s something very strange hidden in this picture.
Black holes don’t emit light, but they still shine. They do so because of accretion disks, but those disks don’t appear around black holes of all sizes. There could be incredibly huge black holes out in the universe that we can’t see, because they’ve gone really dark.
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…
You’ve heard it before: In space, no one can hear you scream. That’s because sound doesn’t move through a vacuum, and everyone knows that space is a vacuum. The thing is, that’s not completely true.
