Space Weather News for May 3, 2007 --------------- HALLEY'S METEORS: http://spaceweather.comEarth is entering a stream of dust from Halley's Comet, and this will produce a meteor shower (the "eta Aquarids") peaking on May 6th. Unfortunately, moonlight will interfere with the display, wiping out all but the brightest meteors. People who wake up before dawn on Sunday and look east might nevertheless catch a few specks of Halley's comet disintegrating in Earth's atmosphere. SPARKLING SUNSPOT: Sunspot 953, which emerged one week ago, has proven to be one of the most photogenic sunspots in years. For one thing, it is crackling with micro solar flares (sometimes called "Ellerman Bombs"); this makes the sunspot appear to sparkle when viewed through the eye piece of a backyard solar telescope. There's also an active magnetic filament winding outward from the sunspot's dark core. So far, no major solar flares have issued from this active region, but it's still a great show.
8. NASA Science News for May 1, 2007 ----------- Fantastic Flyby <http://science.nasa.gov/headlines/y2007/01may_fantasticflyby.htm?list111411>http://science.nasa.gov/headlines/y2007/01may_fantasticflyby.htm?list111411NASA has released stunning new images of Jupiter and its moons taken by the New Horizons spacecraft. Highlights include a movie of a volcanic eruption on Jupiter's moon Io; a nighttime shot of auroras and lava on Io; a color photo of the "Little Red Spot" churning in Jupiter's cloudtops; images of small moons herding dust and boulders through Jupiter's faint rings. The gallery featured in today's story is a must-see.
9. NASA Science News for May 4, 2007 <http://science.nasa.gov/headlines/y2007/04may_methaneblast.htm?list111411>http://science.nasa.gov/headlines/y2007/04may_methaneblast.htm?list111411NASA-supported scientists and engineers have successfully tested a methane-powered rocket engine. The firing was not only remarkably beautiful (a must-see movie is featured in today's story) but also may herald a new type of spacecraft that one day roams the outer solar system gathering fuel from planets and moons that it visits.

Discovered in 1932, Apollo was the first asteroid recognized to cross Earth's orbit. Its discovery, and the subsequent discovery of many others like Apollo, helped scientists understand that the threat of asteroid impacts didn't end with the dinosaurs; it's a modern problem, too. There's no danger of a collision this time. Apollo will be about 10.7 million kilometers away at closest approach on May 8th. Southern hemisphere astronomers with big backyard telescopes may be able to photograph the 1.7 km-wide asteroid and its tiny 75 meter-wide moon gliding through the constellations Microscopium and Grus.
