Black holes could 'bend it like Beckham' to reveal hidden asymmetries of the universe

Black holes and soccer balls don't have much in common, but if black holes are curved when kicked, it might say something deep about the cosmos.

Astronomers unsure what caused 'weird explosion' seen by Einstein Probe's X-ray eye

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a gamma-ray burst, or by something entirely new?

Are planet-killing black holes hiding inside your cat?

New research suggests that tiny primordial black holes could be hollowing out planets and passing through everyday objects, maybe even you and your cat!

Newfound dead star spins record-breaking 716 times a second, explodes with thermonuclear blasts

The neutron star 4U 1820-30 is one of the fastest spinning bodies in the universe, spinning at 716 times a second and erupting like an atomic bomb, NASA's NICER telescope has found.

Space

Dark matter might live in a dense haze around stellar corpses

The extreme qualities of neutron stars could mean these dead stellar remnants gather dense clouds of hypothetical particles called "axions" around them, potentially shedding light on dark matter.

Real-life 'Star Trek' planet was actually just an illusion caused by a 'jittery' star

New research shows that a planet spotted around the real-life star 40 Eridani A, famous for hosting Dr. Spock's fictional home world in 'Star Trek', may have been an optical illusion all along.
