The findings, published in The Astrophysical Journal, provide fresh insights into ultraluminous X-ray sources (ULXs) — among the brightest and most enigmatic objects known in astrophysics.

Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours.

Indian scientists from Raman Research Institute have uncovered the mystery behind repeating X-ray flares from a stellar-mass ...

Gamma-ray bursts are a relatively new field in space science. The first was discovered in the late 1960s, and in the nearly six decades since, there’s never been a discovery quite like this. It may ...

A jetliner was nearly knocked out of the sky and sent plummeting to a deadly crash that would have killed all onboard by a bizarre attack from outer space – an explosive burst of cosmic rays sent ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...
