Astronomers find planet hotter than most stars

A newly discovered Jupiter-like world is so hot, it’s being vaporized by its own star. With a dayside temperature of more than 7,800 degrees Fahrenheit, KELT-9b is a planet that is hotter than most stars. But its blue A-type star, called KELT-9, is even hotter — in fact, it is probably unraveling the planet through evaporation.
