A gravitational wave event detected in 2019 might have led astronomers to discover the first wormhole in the universe. LIGO and Virgo picked up the wave that lasted less than a tenth of a second.

When night falls in the Atacama Desert in northern Chile, brilliant constellations shine down on the dry plains.

But those claims were quickly met with pushback. Independent analyses of the same JWST data suggested the team's evidence for ...

Asteroid 2023 CX1 was observed in February 2023, seven hours before entering the atmosphere, and disintegrated at a very low latitude above the surface.

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the ...

Many planetary systems are born in slightly tilted protoplanetary disks, which would explain the misaligned orbits from the ...

Astronomers from the University of Hawaii’s Institute for Astronomy have identified a new category of events that they found ...

With help from amateur astronomers, scientists tracked how an asteroid traveled from space, broke up in Earth's atmosphere ...

The final solar eclipse of 2025, a partial ‘Surya Grahan,’ occurs on September 21–22. While India will miss the live event, ...

The GW190412 merger revealed a black-hole recoil moving faster than 50 km/s. Gravitational waves allowed its 3D motion to be reconstructed. A research group led by the Instituto Galego de Física de ...

Astronomers have witnessed a rare “extremely stripped supernova” that exposed the inner silicon layers of a dying star, confirming theories of stellar fusion and offering new insight into how ...

New simulations suggest Earthlike planets may be much more typical than previously thought whereas water worlds may not.
