Space Weather News for May 3, 2007 --------------- HALLEY'S METEORS:
Earth 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.

NASA Science News for May 1, 2007 ----------- Fantastic Flyby
NASA 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.

NASA Science News for May 4, 2007
NASA-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.

Marine Advanced Technology Education Center
     offers over 100 interviews with marine technology
     professionals.  Learn what it's like to be a commercial diver,
     software engineer, electrician, environmental cleanup and
     monitoring technician, fish and game warden, fisher,

     National Science Foundation)

Microscope Imaging Station
     shows what blood is, what happens when the immune system goes
     awry, and what are stem cells are.  See videos of cell
     structure and function, cell development and motility,
     plankton, plants, and protozoa.  Learn how the sea urchin
     helps us understand genes, reproduction, and cancer.

Practical Uses of Math and Science
     features more than 60 examples of how science and math can be
     used in interesting settings and everyday life.  Topics
     include clouds (why they float), social security benefits
     (algebra), Pythagorean theorem (cabinet corners), ice sheets
     and sea level, logarithms, matching birthdays (statistics),
     natural selection and a scavenger hunt, photons, traffic
     signals (probability), seasons (causes), volcanic clouds, wind
     chill (algebra), and more.  (National Aeronautics and Space

Solar System
     examines the solar system and NASA explorations in it.  Learn
     about how the solar system formed, what we know about Mars,
     and the likelihood of earth colliding with an asteroid or
     comet.  (National Aeronautics and Space Administration)

     explores questions that include: How do galaxies and stars
     form? What powered the Big Bang? What is dark energy and how
     is it pulling the universe apart? Is the universe expanding?
     What happens at the edge of a black hole? Is there life beyond
     earth? (National Aeronautics and Space Administration)

Space Weather News for May 7, 2007
ASTEROID FLYBY: This week, a famous asteroid is flying past Earth: 1862 Apollo. 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.
