A colossal ring of gas has been revealed around Jupiter by NASA's Cassini space probe.
The cloud is composed of water and lies along the orbit of Jupiter's icy moon Europa, 670,000 kilometres from the planet. Researcher think the cloud is generated by radiation from Jupiter bombarding the surface of Europa. Physicists from Johns Hopkins University, Maryland, studied measurements taken by Cassini as it flew past Jupiter in late 2000 and early 2001. They conclude that the gas cloud both generates and attracts charged radiation particles and thus helps to maintain Jupiter's magnetosphere - the region influenced by the planet's magnetic field. http://www.newscientist.com/news/news.jsp?id=ns99993450 |
