Astronomers have stumbled upon a pair of massive black holes in a distant galaxy that are triggering unusual bursts of light.

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a ...

NASA's Swift Observatory revealed twin 'monster' black holes devouring a gas cloud in a distant galaxy, creating recurring ...

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from ...

The tidal event theory is still on the table, only it is now attributed not to an exploding star, but to a gas cloud that's bigger than the binary black hole system itself. The theory belongs to a ...

An international team of astronomers has conducted a multiwavelength study of an X-ray binary designated 1eRASS ...

Astronomers, using data from NASA’s Swift Observatory, have identified an extraordinary recurring signal from two massive black holes in a galaxy a billion light-years away. Known as AT 2021hdr, this ...

The universe is home to many fascinating objects. R Aquarii is a binary star system with a red giant and a white dwarf. Omega ...

One idea was that AT 2021hdr was a tidal disruption event (TDE) ,] where a star strays too close to a black hole and is ripped apart. This can create periodic bursts as the stellar remnant orbits the ...
