Spacetime singularities might exist unhidden in strangely curved universes
A new study pursues a kind of “paleontology” for gravitational waves in an attempt to explain how and why black holes collide and merge.
Astrophysicists at the University of Birmingham have made progress in understanding a key mystery of gravitational-wave astrophysics: how two black holes can come together and merge.
Ever since first mentioned by Jon Michell in a letter to the Royal Society in 1783, black holes have captured the imagination of scientists, writers, filmmakers and other artists. Perhaps part of the allure is that these enigmatic objects have never actually been “seen”. But this could now be about to change as an international team of astronomers is connecting a number of telescopes on Earth in the hope of making the first ever image of a black hole.
In the center of a distant galaxy, almost 300 million light years from Earth, scientists have discovered a supermassive black hole that is “choking” on a sudden influx of stellar debris.
Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.
The massive black hole is able to rapidly grow as intense radiation from a galaxy nearby shuts down star-formation in its host galaxy.
Astronomers have found evidence of a star that whips around a likely black hole twice an hour. This could be the tightest orbital dance ever seen by a black hole and a companion star in our own Milky Way galaxy.
