Supernova
Speaking of youth, a 14-year-old, Caroline Moore, found a supernova that baffles scientists:
Her discovery did indeed turn out to be a supernova, but it goes against all the rules we thought we knew. For example, it’s in a galaxy that’s in the process of “eating itself,” UGC 12682, where supernovas don’t usually occur. It’s also one of the least luminous supernovas ever detected, and scientists haven’t found any evidence of hydrogen, which usually turns up around dimmer supernovas. Now scientists are theorizing that the lack of hydrogen may stem from the fact that this was a massive star that lost mass. Perhaps its core collapsed into a black hole without transferring any energy to the outer layers of the star.
