A mysterious "rogue" planet has been observed gobbling six billion tonnes of gas and dust a second -- an unprecedented rate that blurs the line between planets and stars, astronomers said.

These storms are thought to contain a kind of water-ammonia hail ('mushballs') specific to Jupiter's atmosphere, which drags the ammonia down into the deep atmosphere and may explain the presence of ...
