An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger ...

Using the James Webb Space Telescope, an international team of researchers has discovered chemical fingerprints from enormous ...

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 ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

A new study suggests that "little red dots" spied by the James Webb telescope could be the universe's short-lived first ...

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

A sweeping new ALMA image has peeled back the veil on the Milky Way’s core, exposing a dense network of cold gas filaments ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

A fresh analysis of gravitational wave data from a 2020 collision between a black hole and a neutron star has produced the first measured evidence of an eccentric, oval-shaped orbit in this type of ...

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist ...

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