Star pummeling alien planet with X-ray attack

A nearby star is drubbing its close-orbiting planet with a barrage of X-rays 100,000 times more powerful than what the Earth receives from the sun, a new study has found.

That intense, high-energy radiation is blasting about 5 million tons of matter from the gigantic planet into space every second, researchers said. They made the observations using NASA's Chandra X-Ray Observatory and the European Southern Observatory's Very Large Telescope in Chile.

"This planet is being absolutely fried by its star," said study lead author Sebastian Schroeter, of the University of Hamburg in Germany, in a statement. "What may be even stranger is that this planet may be affecting the behavior of the star that is blasting it."
