A star must live in a relatively tranquil cosmic neighborhood to foster planet formation, say astronomers using NASA’s Spitzer Space Telescope. A team of scientists from the University of Arizona’s Steward Observatory, Tucson, came to this conclusion after watching intense ultraviolet light and powerful winds from O-type stars rip away the potential planet-forming disks, or protoplanetary disks, around stars like our sun. At up to 100 times the mass of the sun, O stars are the most massive and energetic stars in the universe. They are at least a million times more powerful than the sun.
