Subscribe to Space Weather News!  SUNSET ECLIPSE: Don't miss it on Monday: a partial solar eclipse. Across much of North America the setting Sun will become a strange-looking crescent when the Moon glides in front of our star. Read the full story from Science@NASA.
WARNING: Never stare at the Sun! Sunlight can blind you even during an eclipse. Click here for safe observing tips. SOLAR BLAST: An enormous magnetic loop filled with glowing-hot gas lifted off the Sun on June 9th. Astronomers call such events "prominences" -- they're caused by explosive instabilities within the Sun's tangled magnetic field. This one stretches about 50 Earth-diameters from one end to the other.  Above: An ultraviolet telescope onboard the Solar and Heliospheric Observatory captured this spectacular view of the prominence at 13:19 UT on June 9th. JUPITER AND THE MOON: Step outside just after sunset on Wednesday, June 12th, and look west. The planet Jupiter and the slender cresent Moon will appear side-by-side -- a lovely sight. While you're there, check out the ghostly glow of Earthshine across the Moon's dark terrain!

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 are on a collision course with our planet, although astronomers are finding new ones all the time.
On 10 Jun 2002 there were 438 known Potentially
Hazardous Asteroids June 2002 Earth-asteroid encountersNotes: LD is a "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.  - COMET IKEYA-ZHANG: The brightest comet in years delighted sky watchers in March and April 2002. [gallery]
