In a first, researchers have discovered that certain primordial stars - those between 55,000 and 56,000 times the mass of our Sun - may have died unusually by exploding completely and leaving no remnant black hole behind.
Over billions of years, small black holes can slowly grow supermassive by taking on mass from their surroundings and also by merging with other black holes.
A new X-ray study of the remnants of an exploded star suggests that the supernova that disrupted the massive star may have turned it inside out in the process.
A huge ball of brightly burning gas
may be the heaviest star ever discovered.
