Black holes represent some of the most extreme environments in the universe. They are the sources of the strongest gravitational fields, allowing us to test Einstein's theory of general relativity to an extent impossible ...
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...
Physicists have discovered a surprisingly simple way to reproduce one of the most fascinating models in modern physics—linked to black holes, quantum chaos and exotic electronic materials—using ultracold atoms trapped in ...
Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
A black hole may be stirring a "pot" of gas containing a neighboring galaxy in the early universe, according to a new study published in Astronomy & Astrophysics that used observations from NASA's Chandra X-ray Observatory. ...
The first-ever image of a black hole—a glowing, ring-like structure at the heart of galaxy M87—was unveiled to the world in a landmark moment in 2019. Now, researchers have taken the next big step—moving beyond capturing ...
Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational interactions, Newton's theory of universal gravitation works just fine. Newton's model is good enough ...
For the third time in 35 years, the black hole at the center of the galaxy IC 3599 has erupted, and this time, astronomers were watching it closely. IC 3599, a galaxy roughly 280 million light-years away, has flared this ...
Listening to the "ringing" produced by black holes after they collide and merge could allow scientists to test Einstein's theory of general relativity under the most extreme conditions in the universe while unlocking the ...
Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding ...
