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 ...

In an inversion of the well known scenario of a black hole devouring a star, the researchers propose that a star actually swallowed a black hole. Once subsumed, the massive infiltrator begins to rip ...

Stars often fall into black holes, and now it seems the opposite can also occur, producing an extra long-lasting explosion as the star is consumed from within ...

On July 2, 2025, NASA's Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours' worth of signals that appeared to come from the same source. When scientists compiled this data with ...

Astronomers recorded the longest gamma-ray burst in history, GRB 250702B, that may be a cosmic event completely new to science.

Considering the immense size of the universe, it's no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen ...

New X-ray observations reveal Betelgeuse’s mysterious companion is not a collapsed stellar remnant but a young, Sun-like F-type star orbiting the massive red supergiant.

Looming billions of light years away, astronomers have spotted an enormous double-ring structure — itself hundreds of thousands of light years across — that glows spectacularly in radio wavelengths.

"This is truly extraordinary," Itai Sfaradi of the University of California, Berkeley, said in a statement. "Never before have we seen such bright radio emission from a black hole tearing apart a star ...

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed ...

A black hole far from its galactic center has unleashed the fastest, brightest radio flares ever seen from a star’s destruction. For the first time, astronomers have detected a tidal disruption event ...
