JUPITER MOON MOVIE: An amateur astronomer in Australia has photographed a
very rare event--one of Jupiter's moons eclipsing another. Earth is now
passing through the orbital plane of Jupiter's satellite system allowing
such "mutual occultations" to be seen through backyard telescopes. Check
http://spaceweather.com for a movie of Europa passing directly in front of
Ganymede and links to more information for observers who wish to try to
record such movies themselves.
SATELLITE DEBRIS: On Feb. 10, 2009, Iridium 33 crashed into Cosmos 2251 and
the two satellites were shattered. Since then, US Strategic Command has
catalogued nearly a thousand pieces of debris. Today's edition of
http://spaceweather.com presents 3D maps showing where the fragments are
located on the three-month anniversary of the unprecedented collision. One
large piece of Iridium 33 wreckage is visible to the naked eye as it tumbles
through the night sky flashing every 4.7 seconds. Check the Simple Satellite
Tracker for flyby times: http://spaceweather.com/flybys
