NASA discovers universe's edge 600 million light-years away; captures 3 black holes devouring stars.

NASA's recent findings reveal three supermassive black holes consuming stars, resulting in extreme nuclear transients. These events, among the most energetic cosmic explosions since the Big Bang, release energy exceeding 100 supernovae. Data from NASA's Swift Observatory and WISE spacecraft confirm these dramatic stellar interactions, involving stars three to ten times the mass of our Sun.

 University of Hawaiʻi's Institute for Astronomy (IfA) have discovered the most energetic cosmic explosions yet discovered, naming the new class of events "extreme nuclear transients" (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. Their disruption releases vast amounts of energy visible across enormous distances.

ESA (European Space Agency), and other institutions describes three extreme examples of supermassive black holes feasting on massive stars. These events released more energy than 100 supernovae, and represent the most energetic type of cosmic explosion since the big bang discovered so far.

Each supermassive black hole sits at the center of a distant galaxy, and suddenly brightened when it destroyed a star three to 10 times heavier than our Sun. The brightness then lasted for several months.

Scientists describe these rare occurrences as a new category of cosmic events called “extreme nuclear transients.” Looking for more of these extreme nuclear transients could help unveil some of the most massive supermassive black holes in the universe that are usually quiet.

In a remarkable extension of this research, astronomers pinpointed a tidal disruption event (TDE) named AT2024tvd located 600 million light-years away . This phenomenon features a wandering black hole consuming a star while not positioned at its galaxy's center. The discovery is groundbreaking as it represents the first identification of an offset TDE. The smaller black hole’s distance from its larger counterpart—over one million solar masses—highlights intriguing dynamics within galactic structures .
