In new study, astronomers trace X-ray bursts to stellar debris around black hole

AstroSat, along with observatories Chandra, HST, NICER, and Swift, found that a massive black hole has torn apart one star and is now using that stellar wreckage to “pummel” another star or smaller black hole. This discovery links two mysteries with a largely unestablished connection, ISRO said on Thursday.

'Thermometer' molecule found on exoplanet could help determine similar exoplanets' temperatures

The molecule, chromium hydride (CrH) and sometimes referred to as a 'thermometer for stars', has previously proved its usefulness in determining temperatures of certain types of stars such as cool stars and brown dwarfs.
