In the zoo of subatomic particles, neutrinos are strange beasts. Unlike more familiar particles such as electrons and protons, ghostly neutrinos barely interact with normal matter: they can fly through a planet as if it isn’t even there. This makes them extremely difficult to detect and, for neutrinos from cosmic objects in the sky, even …

Credit: Cao et al, 2022 Using NASA’s Chandra and ESA’s XMM-Newton space telescopes, astronomers from Radboud University in the Netherlands and elsewhere made X-ray observations of a tidal disturbance event designated 3XMM J150052.0+015452, or J150052 for short. The results show that J150052 was triggered by a rapidly rotating …

Bartmann Since 2015, the LIGO-Virgo-KAGRA collaboration has detected around 85 pairs of colliding black holes. We now know that Einstein was right: gravitational waves are generated by these systems as they wind around each other, warping spacetime …

Image: Carl Knox – OzGrav, ARC Center of Excellence for Gravitational Wave Discovery, Swinburne University of Technology On a clear night last February, a sophisticated astronomical camera perched on top of a California mountain opened its eyes to the sky after being turned off for several days due to problems. The timing turned out to …
Scientists have created a lab-grown black hole analog to test one of Stephen Hawking’s most famous theories – and it’s behaving exactly as he predicted. The experiment, created using a string of single-file atoms to simulate a black hole’s event horizon, added further evidence to Hawking’s theory that black holes should emit a faint glow …
