What should you do if you see a really bright meteor? Is there anyone you should tell?

In case you were wondering, this seems to be the most common question that I get asked (usually once a week or so). So, being the human link librarian that I am, I thought I'd provide you with a set of Internet resources you can use if you see such an event for yourself.

If you're watching the sky, and you suddenly see a really, REALLY, bright meteor (at least as bright as Venus, at -4 magnitude) streaking overhead, then you're seeing a "fireball" - a meteor that stands a pretty good chance of getting through the Earth's atmosphere without burning up (they always seem to land on cars, don't ask me why ;-). The slower the fireball moves through the sky, the better chance there will be of finding it on the ground.

If you see a fireball, it's very important that you report the sighting to your local agency, so they can try and recover the meteorite on the ground. Your visual data can allow experts to calculate the atmospheric trajectory and orbit information. And since meteorites react with the Earth's atmosphere right away, it's important to locate them quickly.

In the United States, you want to contact the American Meteor Society:

In Canada, the meteorites and Impact Advisory Committee:

CHANDRA IMAGES GALACTIC SUPERBUBBLES

The Chandra X-Ray Observatory was recently used to reveal incredible detail on what happens when Galaxies collide. The collision of the two Antennae Galaxies in the constellation Corvus has produced "superbubbles" 5,000 light years across. As the Galaxies collide, the pressure causes clouds of gas to form into stars. These short-lived new stars go supernova only a few million years later, and their expanding clouds merge to form the superbubbles imaged by Chandra. The space observatory recently celebrated its one year anniversary.

ARIANE ROCKET LAUNCHES TWO SATELLITES

An Ariane 44LP booster carrying two satellites successfully launched from the European Space Agency (ESA) launch center in Kourou, French Guiana. The launch occurred Thursday evening at 11:16pm GMT, with its cargo of a Brazilian Brasilsat B4 communications satellite, and an Egyptian Nilesat 102 direct television satellite. Both satellites were placed in their correct orbits within 25 minutes of launch. This is the 5th launch of the year for Arianespace.

NASA PIONEER DIES

An architect of modern spaceflight, Dr. Robert Gilruth, died early yesterday at a long-term care facility in Charlottesville, Va; he was 86. Back in the 50s, Dr. Gilruth led a team that created the basic design for Project Mercury, which put the first American in space. He then went on to become the directory of the Manned spaceflight Center, now the Johnson Space Center in Houston. Over the course of his career he directed 25 manned flights.

TITAN LAUNCH SUCCESSFUL

A Titan 4B rocket lifted off from the Vandenberg Airforce Base in California at 11:45pm GMT. 9 minutes and 45 seconds after launch, it separated its classified secret payload into a successful orbit. Although its payload is classified, industry experts suspect that the rocket was carrying a Lacrosse radar imaging reconnaissance satellite for the National Reconnaissance Office.
