MISSING SUPERNOVAS: Astronomers have long believed that stars explode in the Milky Way about once every 50 years. Yet the last time anyone actually witnessed a supernova was in the year 1680. Where are all the missing supernovas? At long last, NASA's Chandra X-ray Observatory has found one: full story.
LUNAR TRANSIT: Last night, the International Space Station flew over Slovakia--and right in front of the Moon. A team of astronomers led by Roman Piffl had their Nikon D200 ready and they caught the winged silhouette passing just south of the Sea of Tranquillity:

"It was really amazing!" says Piffl. "We were on the centerline of the transit 20 km southeast of Bratislava, the capital of Slovakia."
Now is a good time for Europeans to see the International Space Station with their own eyes. For the next two weeks, the behemoth spacecraft will be making a series of bright flybys of Europe, sometimes three or four times a night. Try our new global Satellite Tracker to find out when to look.
SOLAR VORTEX: "In spite of solar minimum, there seems to be plenty of action on the sun," reports amateur astronomer Peter Schlatter of Wohlen, Switzerland, who yesterday witnessed a spectacular vortex swirling on the sun's eastern horizon.

Indeed, the limb of the sun is where the action is. "A huge prominence emerged today looking like a monster rising from a sea of fire," reports David Leong of Hong Kong: photo. None of this activity is explosive or threatening to cause geomagnetic storms on Earth--it's just a pretty show. If you have a solar telescope, take a look.
