Did you sleep through the auroras of Dec. 14th? Next time get a wake-up call: Spaceweather PHONE.

181 THINGS TO DO: If you woke up tomorrow morning and found yourself on the Moon, what would you do? NASA has just released a list of 181 good ideas: full story.

LIQUID FILAMENT: Warning. Staring too long at this photo may cause sensations of dizziness:


Click to see the filament in motion (8 MB).

Gary Palmer of Los Angeles photographed sunspot 940 yesterday, capturing a dark, magnetic filament swirling up and out of the spot's core. He calls it the "Liquid Filament" because of its fluid motions: 8 MB movie. Sunspot 940 and its vertiginous filament are near the center of the sun this weekend--easy targets for backyard solar telescopes. Take a look!

ODD COUPLE: Last night, the Moon glided beautifully close to the ringed planet Saturn. P-M Hedén took this picture from Vallentuna, Sweden:


Photo details: Orion 80ED 600mm, Canon Digital Rebel XT

"I couldn't see Saturn with the naked eyes because of the Moon's glare" says Hedén, "but when I aimed my Orion 80ED at the moon, the sight was really great--a tiny Saturn with rings right beside our great moon!"

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.

On 3 Feb 2007 there were 832 known Potentially
