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

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery ...

Katherine Courtney and Alice Gorman talk to Margaret Harris about the danger of space debris – and what we need to do about it Jettisoned junk A pallet of old batteries released into space from the ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense. NASA’s DART (Double Asteroid Redirection Test) spacecraft changed the ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

These provide statistical insights into the collisions between the incredibly compact objects that cause them, whether neutron stars or black holes. The new detections have also allowed us to find ...

GW200105 reveals an eccentric orbit before merger, challenging formation models.

On March 16, 1926, the first liquid-fueled rocket launched from Massachusetts.

Astronomers analyzing the gravitational-wave signal from a 2020 collision between a black hole and a neutron star report ...

On March 16, 1926, Clark University professor Robert Goddardfired up a rocket nicknamed “Nell,” powered by a blend of ...

After 14 years in orbit, Nasa’s Van Allen Probe A satellite is expected to re-enter Earth’s atmosphere. How big a threat is ...
