Biggest BOOM since The Big Bang? You bet. Astronomers with the using data from the Keck Observatory Archive (KOA) discovered the most energetic cosmic explosions discovered to date. Dubbed "Extreme Nuclear Transients" or ENTs, these extraordinary phenomena occur when massive stars—at least three times heavier than our Sun—are torn apart after wandering too close to a supermassive black hole, releasing more energy than 100 supernovae. 🤯 👉https://keckobservatory.org/ents/ 🎞: W.

📣BREAKING NEWS: Astronomers using W. M. Keck Observatory have determined the physical properties and potential origin of 2024 YR4, the Earth-crossing #asteroid first discovered by scientists in December 2024. The study reveals YR4 is a solid, stony type that likely originated from an asteroid family in the central Main Belt between Mars and Jupiter, a region not previously known to produce Earth-crossing asteroids.
