The Helium Rains of Jupiter

coondoggie writes "In the strange and mysterious world of Jupiter, scientists were looking for an explanation for why the massive orb's atmosphere contained little neon, a common gas found on many planets. Now researching say they have found solved the mystery: Helium rain. In the interior of Jupiter conditions are so strange that, according to predictions by University of California, Berkeley scientists, helium condenses into droplets and falls like rain. On Jupiter the scientists explain the only way neon could be removed from the upper atmosphere is to have it fall out with helium, since neon and helium mix easily, like alcohol and water."
