Black holes don't erase information, scientists say
The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
Absence of gravitational-wave signal extends limit on knowable universe
Imagine an instrument that can measure motions a billion times smaller than an atom that last a millionth of a second. Fermilab's Holometer is currently the only machine with the ability to take these very ...
New insights found in black hole collisions
New research provides revelations about the most energetic event in the universe—the merging of two spinning, orbiting black holes into a much larger black hole.
Supermassive black hole clears star-making gas from galaxy's core
Many nearby galaxies blast huge, wide-angled outpourings of material from their center, ejecting enough gas and dust to build more than a thousand stars the size of our sun every year. Astronomers have sought ...
Astronomers reveal supermassive black hole's intense magnetic field
Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy. The results ...
Best view yet of dusty cloud passing galactic center black hole
The best observations so far of the dusty gas cloud G2 confirm that it made its closest approach to the supermassive black hole at the centre of the Milky Way in May 2014 and has survived the experience. ...
Flip-flopping black holes spin to the end of the dance
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, said researchers at Rochester Institute of Technology in a paper published ...
Hubble finds phantom objects near dead quasars
NASA's Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are the ephemeral ghosts of quasars that flickered to life and then faded.
How can black holes shine?
We hear that black holes absorb all the light that falls into them. And yet, we hear of black holes shining so brightly we can see them halfway across the Universe. What's going on? Which is it?
Best of Last Week—Black holes don't erase information, a stick computer and the exploding head syndrome
Physicists seek answers on supermassive black holes with the next-gen X-ray telescope
University of Waterloo Professor Brian McNamara along with two Canadian astronomers will be part of the science working group directing ASTRO-H, the Japan Aerospace Exploration Agency's (JAXA's) newest flagship x-ray astronomy ...
Image: Hubble stares into the crammed center of Messier 22
This image shows the center of the globular cluster Messier 22, also known as M22, as observed by the NASA/ESA Hubble Space Telescope. Globular clusters are spherical collections of densely packed stars, ...
White dwarf may have shredded passing planet
The destruction of a planet may sound like the stuff of science fiction, but a team of astronomers has found evidence that this may have happened in an ancient cluster of stars at the edge of the Milky Way ...
Video: How do black holes evaporate?
Nothing lasts forever, not even black holes. According to Stephen Hawking, black holes will evaporate over vast periods of time. But how, exactly, does this happen?
