The updated picture,...

NASA: This Is What a Black Hole Sounds Like

Sound from Perseus galaxy cluster is pretty spooky, listeners say

(Newser) - Sound does exist in space, NASA says—and some of it is pretty spooky. NASA's exoplanets team tweeted a 34-second clip of the sound of a black hole Sunday, saying that while sound waves can't travel in a vacuum, a "galaxy cluster has so much gas that...

New research indicates 'vampire' star is feeding on its neighbor

(Newser) - European astronomers have put out something of a retraction: that black hole said to be the closest to Earth ever found —well, it doesn't exist. They're not too bothered, however. European Southern Observatory emeritus astronomer Dietrich Baade, co-author of the new research, says their error led to...

Among Nobel Winners: Guy Who Proved Einstein Wrong

Physics honor will be split between 3 scientists for their work on black holes

Scientists' Understanding of Black Holes Is Rattled

2 black holes merged into never-before-seen size

(Newser) - Black holes are getting stranger—even to astronomers, who've now detected the signal from a long-ago violent collision of two black holes that created a new one of a size that had never been seen before. "It's the biggest bang since the Big Bang observed by humanity,...

Scientists Just Found Closest Black Hole to Earth

'Washington, DC, would quite easily fit into the black hole'

(Newser) - Meet your new but shy galactic neighbor: A black hole left over from the death of a fleeting young star, per the AP . European astronomers have found the closest black hole to Earth yet, so near that the two stars dancing with it can be seen by the naked eye....

This Black Hole Can't Exist. And There It Is

LB-1 is way more massive than other stellar black holes in our galaxy

(Newser) - A stellar black hole, 70 times the mass of our sun? Not likely, experts said—and yet, there it is. A group of Chinese-led scientists have spotted this "monster" black hole some 15,000 light-years away and dubbed it LB-1, the Washington Post reports. "Black holes of such...

Star Will 'Die All Alone' After Being 'Evicted' by Black Hole

Launched from Milky Way center, S5-HVS1 is going so fast it won't ever be able to get back to our galaxy

(Newser) - A "serendipitous discovery" has been made, and it's an exciting but bittersweet one. Five million years ago, a star got too close to what calls the Milky Way's "heart of darkness"—a supermassive black hole named Sagittarius A* — and got hurled away...

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...

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...

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....

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...

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...
