An international team of astronomers has conducted multiwavelength observations of AT 2023clx—the closest to Earth tidal disruption event (TDE). Results of the observational campaign, published Jan. 22 on the pre-print ...
If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe—a scenario that has occurred during past cold glacial periods.

Roughly 90 percent of the biggest black holes in the known universe are dormant, meaning that they are not actively devouring matter and, consequently, not giving off any light or other radiation. But sometimes a star wanders ...

When a star comes too close to a black hole, the intense gravity of the black hole results in tidal forces that can rip the star apart. In these events, called tidal disruptions, some of the stellar debris is flung outward ...

(Phys.org)—A team of researchers at the University of Aberdeen in the U.K. has had a paper published in the journal Proceedings of the Royal Society B, outlining what they describe as the dangers of living in an "eternal ...
(Phys.org) —Now that it looks like the hunt for the Higgs boson is over, particles of dark matter are at the top of the physics "Most Wanted" list. Dozens of experiments have been searching for them, but often come up with ...
