Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

Astronomers have used the LOFAR telescope array to create the largest radio survey of the cosmos, revealing 13.7 million ...

Detecting supermassive black holes just before their merger would lead to significant advances in astrophysics. To achieve this, a new innovative approach combines the study of the gravitational ...

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Observations from NASA’s James Webb Space Telescope and other telescopes have shown what appears to be a supermassive black hole forming right between two merging galaxies. There have been multiple ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

Two massive galaxy clusters are slamming into each other, and for once astronomers are not reconstructing the crash from the debris long after the fact. They have caught the system in the act, with ...

Astronomers used AI to search 35 years of Hubble data and discovered over 1,300 rare cosmic anomalies hidden in plain sight.

New data confirm that the titanic collisions of galaxies ignite the most powerful active galactic nuclei. Active galactic nuclei (AGN) are phases in which supermassive black holes at the centre of ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...
