Researchers said they have found why some orbits seen in young solar systems seem to be more popular than others. Astronomers have been puzzled as to why giant gas planets like Jupiter and Saturn appear to occupy certain regions in mature solar systems while staying clear of others. Ilaria Pascucci, an assistant professor at the University of Arizona's Lunar and Planetary Laboratory, said the final distribution of planets does not vary smoothly with distance from the star, but has clear...

Pasadena, Calif. - Astronomers have laid down the cosmic equivalent of yellow "caution" tape around super hot stars, marking the zones where cooler stars are in danger of having their developing planets blasted away. In a new study from NASA's Spitzer Space Telescope, scientists report the first maps of so-called planetary "danger zones." These are areas where winds and radiation from super hot stars can strip other young, cooler stars like our sun of their planet-forming materials. The...
