Virtual telescope expands to see black holes
Astronomers building an Earth-size virtual telescope capable of photographing the event horizon of the black hole at the center of our Milky Way have extended their instrument to the bottom of the Earth—the ...
Black hole hunters tackle a cosmic conundrum
Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were ...
Pulsing light may indicate supermassive black hole merger
As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a "binary," or two black holes in such close orbit they are gravitationally ...
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 ...
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 ...
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?
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, ...
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 ...
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 ...
Best of Last Week—Black holes don't erase information, a stick computer and the exploding head syndrome
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?
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.
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.
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.
