This friction could be the reason the corona is 100 times hotter than the surface of the sun. http://www.astronomynow.com/breaking/9908/05trace/index.html IO'S ATMOSPHERE A SPARKLING AURORAL LIGHT SHOW ------------------------ Images of Io taken by Galileo while the moon passed through Jupiter's shadow have shown the moon's atmosphere produces colourful auroral emissions - similar to the Northern Lights on Earth. It's suspected that the aurorae are produced by a combination of powerful electric currents and volcanic plumes. http://www.astronomynow.com/breaking/9908/05io/index.html http://news.bbc.co.uk/hi/english/sci/tech/newsid_412000/412620.stm http://cnn.com/TECH/space/9908/05/io.gases/index.html http://explorezone.com/archives/99_08/06_io_aurora.htm http://www.flatoday.com/space/today/080699g.htm NASA BUDGET CUTS DELAYED ------------------------ The House has decided to postpone a vote until September which could deliver a set of devastating cuts to NASA's budget. If the vote goes through, NASA's budget would be cut by almost $1 billion, which NASA administrator Dan Goldin feels would devastate the agency. http://www.flatoday.com/space/today/080699e.htm To unsubscribe from this newsletter, just reply with only the subject line "UNSUBSCRIBE NEWSLETTER".
