A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep ...

A blazar is an active galactic nucleus, essentially a galaxy with a supermassive black hole at its heart, devouring ...

Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the ...

The search for the origin of a mysterious ultra-energetic cosmic neutrino detected in 2023 may have finally reached a 'blazing' conclusion ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of physics.

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Supermassive black holes spiral towards each other in this simulation created by NASA's Goddard Space Flight Center that shows how they glow in ultraviolet and X-ray light. The black holes are only 40 ...
