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 ...

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 ...

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 ...

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

Their formation has been an object of debate, but new observations confirm the lead hypothesis: they are the product of incredibly bright supernovae. The rest of this article is behind a paywall.

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, ...
