The central supermassive black holes in galaxies likely spent their early formative epochs feasting on a smooth diet of stars and gas . That history is reflected in their spin rates .

A recent survey of supermassive black holes reveals that their spin rates reveal something about their formation . history If you want to describe a supermassive black hole’s characteristics ,

Scientists can directly measure their power , their spin , and their eventual fallout , whether that’s turning into a black hole or a neutron star in some cases or just a much smaller stellar remnant . One of these events happened around 350 years ago or around 11,000 years ago from the star’s perspective in the constellation Cassiopeia . The James Webb Space Telescope recently caught a glimpse of the aftereffects of the explosion , and it happened to shed light literally on a familiar area of study

Currently , 5,819 exoplanets have been confirmed in 4,346 star systems , while thousands more await confirmation . The vast majority of these planets were detected in the past twenty years , owing to missions like the Kepler Space Telescope the Transiting Exoplanet Survey Satellite TESS the venerable Hubble the Convection , Rotation and planetary Transits CoRoT
