In 2022 on October 8, an intense pulse of gamma-ray radiation swept through our solar system. The source, dubbed GRB 221009A for its discovery date, turned out to be the brightest gamma-ray burst (GRB) ever recorded. GRB 221009A lasted over 300 seconds. According to astronomers, such “long-duration” GRBs are the…

On October 9, 2022, an intense pulse of gamma-ray radiation swept through our solar system, overwhelming gamma-ray detectors on numerous orbiting satellites, and sending astronomers on a chase to study the event using the most powerful telescopes in the world. The new source, dubbed GRB 221009A for its discovery date,…

A new…

Our universe began with a puzzle. For 100 million years after the big bang, it expanded. Then something strange happened — this expansion suddenly accelerated and has continued to accelerate ever since. Today cosmologists think some kind of pressure must have forced this acceleration, all powered by huge amounts of…

Observations of supermassive black holes at the centers of galaxies point to a likely source of dark energy – the ‘missing’ 70% of the Universe. ​The measurements from ancient and dormant galaxies show black holes growing more than expected, aligning with a phenomenon predicted in Einstein’s theory of gravity. The…

A new paper has proposed an absolutely wild idea. What if aliens are creating black holes to use as quantum storage? It sounds crazy, but some scientists say it could give us a solution to the Fermi Paradox, which essentially states that if life is common in our universe, why…

Home News The so-called Tadpole near the galaxy's center could be the victim of a rare, intermediate-mass black hole. (Image credit: Keio University) An enormous, deformed dust cloud that astronomers nicknamed "the Tadpole" could point to the location of an extremely rare type of black hole never confirmed to exist…

Observations have found black holes spanning 10 orders of magnitude in mass across most of cosmic history. The assembly of stellar and supermassive black hole (SMBH) mass in galaxies can help to diagnose the origins of locally observed correlations between SMBH mass and stellar mass.   A team of researchers led…
