It turns out a vintage Russian rocket (launched in 1975) reentered the atmosphere, causing a bright fireball and a strange smoke trail. Here's an article about it: http://www.cnn.com/2001/TECH/space/09/06/rocket.debris/index.html Fraser Cain Publisher Universe Today ************************************** -- UNIVERSE TODAY STORY SUMMARY -- * More Support for Life on Mars? * Hubble Points at a Starburst Galaxy * Chandra Measures Galactic Cluster's Dark Matter MORE SUPPORT FOR LIFE ON MARS? ------------------------- Hungarian scientists believe they've found evidence of life on Mars by looking through some of the photographs taken by the Mars Global Surveyor. Three scientists think that dark blue spots visible in the photographs are patches of organisms living beneath the ice. A warning on the Mars Global Surveyor page cautions people from jumping to any conclusions about the spots, though, and the team's theory has been met with skepticism from many members of the scientific community.

The latest photo from the Hubble Space Telescope shows how the galaxy contains hundreds of star clusters - far more than a normal galaxy - each of which is a nest of star formation. Astronomers believe this class of galaxy, called Starburst Galaxies, can be caused by a catastrophic collision between two galaxies.

The team determined this figure by measuring the amount of visible matter, and then calculating how much more would be required to keep the cluster from flying apart - the dark matter's gravity is keeping the cluster together, they believe.
