Black Holes Contain a Mysterious Force

Some of them are helping the universe expand, study says

(Newser) - Black holes are dense singularities that suck up matter, right? Not always, according to two scientists who say some black holes are likely objects filled with a mysterious energy. In Astrophysical Journal , Kevin Croker and Joel Weiner argue that the expansion of the universe—which is accelerating, apparently due to... More »

Planet 9 Might Not Be a Planet

Two young PhDs offer a bold new theory

(Newser) - "What if Planet 9 is a Primordial Black Hole?" That's the title of a new paper about the mysterious gravity source at the edge of our solar system, Business Insider reports. Posted Tuesday on arXiv , the paper suggests that the still-unseen source—which some call Planet Nine, or... More »

Trolls Target Female Scientist

Online commentators diminish the work of Katie Boumann

(Newser) - Katie Boumann's rise to scientific stardom came with a downside: online trolls who claimed her work was really done by a man, CNN reports. The 29-year-old MIT graduate helped create the algorithms and imaging process that allowed scientists to produce the first-ever image of a black hole on Wednesday.... More »

This Isn't Just a Black Hole. It's 'Powehi'

A Hawaiian name is given in honor of its contribution

(Newser) - "As soon as he said it, I nearly fell off my chair." That was the reaction from the deputy director of the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. It's one of two telescopes on Mauna Kea that was used to produce the first-ever image of... More »

Black Hole Image Makes a Star Out of Scientist

Katie Bouman's team developed needed algorithm

(Newser) - For the rest of the world, it was an incredible first: a stunning image of a black hole 55 million light-years from Earth. For Katie Bouman , it was all that, plus the culmination of three years of work, the realization of a goal that scientists thought to be impossible, and... More »

This Is a Sight No Human Has Ever Seen Before

Black hole is in the galaxy Messier 87, or M87

(Newser) - Mankind has now something it has never seen before: an image of "the most mysterious objects in the universe"—the black hole. On Wednesday, six simultaneous press conferences were held around the globe, in Washington, Brussels, Santiago, Shanghai, Taipei, and Tokyo, reports Reuters . There, researchers shared the first...

We May Soon See Something 'No Human Has Ever Seen'

Scientists may reveal photo of Sagittarius A* black hole in Milky Way

(Newser) - Mark your calendars for Wednesday, April 10: You won't want to miss the chance to possibly see "something no human has ever seen before." That's how Popular Mechanics is framing the big reveal scientists are expected to make—a photo of Sagittarius A*, a black hole... More »

Our Milky Way Is Headed Toward a Violent 'Merger'

But we've got about 2 billion years to prepare

(Newser) - It'll be a fireworks show for the ages, but you won't be around to see it. Consider that a blessing in disguise: The display expected by astrophysicists at Durham University in the UK will only come as a nearby galaxy smashes into our own in about 2 billion... More »

Milky Way's Center Is a Black Hole 'Farm'

Researchers believe there are thousands

(Newser) - The center of our galaxy is teeming with black holes, sort of like a Times Square for strange super-gravity objects, astronomers have discovered. For decades, scientists theorized that circling in the center of galaxies, including ours, were lots of stellar black holes, collapsed giant stars where the gravity is so... More »

Scientists Detect 2nd Gravitational Wave From Crashing Black Holes

A crucial second note heard in soundtrack of chaotic cosmos

(Newser) - Astronomers say they've heard the echoes of two more crashing black holes—a discovery that hints that the unseen violence of the universe may be pretty common, the AP reports. They detected a second gravitational wave. That's the warp in the fabric in the cosmos that Albert Einstein... More »

Rumors of a Massive Physics Discovery Swirl

'Probably a shoo-in for this year’s Nobel Prize in Physics'

(Newser) - Rarely does a tweet not involving a Kardashian or a cat stir up such a swell of excitement. On Monday, physicist Lawrence Krauss tweeted that scientists may have discovered gravitational waves, phenomena first predicted by Albert Einstein more than 100 years ago but never observed, Gizmodo reports. "If true... More »

Hawking's New Theory: 'There Are No Black Holes'

He addresses conflicting theories of physics

(Newser) - Stephen Hawking helped develop current theories on black holes—but now, he's saying there aren't any. New Scientist explains his thinking, focusing on what's known in physics as the "firewall paradox," which deals with a black hole's event horizon. That's an "invisible... More »

Secrets of Mysterious Black Hole Jets Revealed

Jets have power to spew iron and nickel, study finds

(Newser) - For years, astronomers have wondered what exactly black holes spew into our universe—and now they know. Iron and nickel have been found shooting from the relativistic jets of a black hole several times larger than our sun, but the finding is more surprising than it may seem. It shows... More »

NASA Spots Nearby 'Young' Black Hole

Could it be a gateway to another universe?

(Newser) - NASA has spotted what appears to be the galaxy's newest black hole—and it's relatively nearby. The Chandra X-Ray Observatory has spotted the aftermath of a super nova that, from Earth's vantage point, is just 1,000 years old, the agency reports . (Of course, it's 26,... More »

Massive Black Hole Stumps Scientists

Its mass equals 17B suns, turning previous theory on its head

(Newser) - An enormous, newly discovered black hole has scientists questioning what they thought they knew about black holes to begin with. Usually, supermassive black holes make up about 0.1% of the mass of the stars at a galaxy's center, known as a stellar bulge. But in this case, the... More »

Strange New Kind of Galaxy Spotted

Infrared survey uncovers 'menagerie of hidden objects'

(Newser) - After two years of scanning the night sky, NASA's WISE infrared telescope has spotted millions of supermassive black holes and a type of galaxy never seen before. The hot, dust-obscured galaxies—hot DOGs—are very rare. Each emits as much light as 100 trillion suns, hidden behind a vast... More »

NASA's 2-Year Hunt for Black Holes Starts Today

NASA's NuStar scheduled to launch from South Pacific

(Newser) - Barring any mishaps, a refrigerator-size telescope will begin its two-year quest to track down black holes today. The Nuclear Spectroscopic Telescope Array (NuStar) is set to rocket into space from an island located between Hawaii and Australia, reports the AP . Once it gets some 350 miles above Earth, it will... More »

Coming Soon: First-Ever Picture of a Black Hole

It will take an array of 50 telescopes to spot its shadow

(Newser) - How do you photograph a black hole, which is normally invisible due to the fact that its gravity is so intense it pulls in even light ? You probably won't be surprised to hear that it's never been done before—and that to do it for the first... More »

Local Black Hole About to Chow Down

Milky Way's super-massive black hole to devour gas cloud

(Newser) - The super-massive black hole at the heart of our galaxy is about to have a feast—and astronomers think it's going to be messy. A giant gas cloud has been spotted approaching the black hole, which lies some 27,000 light years from Earth. Scientists believe the cloud will... More »

Vast New Black Holes Shatter Record

They're 10 times the size of our solar system
