Home News An illustration showing a black hole sucking in material from its accretion disk. The recently detected Camel explosion could have been a black hole's birth. (Image credit: NASA/JPL-Caltech) In October 2020, astronomers detected an enormous, ancient explosion tearing through a galaxy several billion light-years from Earth. The blast…

Variations in the brightness of light seen from around a stellar-mass black hole in the binary system MAXI J1820+070 were caused by a huge warp in its accretion disk, according to a paper to be published in the Monthly Notices of the Royal Astronomical Society. The discovery was made from…

The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles' origins remain unexplained. Now, an international research team has proposed a scenario that explains these; black holes with low activity act as major factories of high-energy cosmic particles.…

The intermediate-mass black hole in question was caught in the act of swallowing a star, called a tidal disruption event. Dubbed 3XMM J215022.4-055108, the event occured in a star cluster associated with a lenticular galaxy at distance of almost 800 million light-years away. An artist’s impression of a black hole…
