Updated: Today at 2247 UT Coronal Holes:
A small coronal hole is growing east of the Sun's central meridian. The many speckles in this image are caused by energetic solar particles striking the camera -- the result of an ongoing radiation storm around Earth. Image credit: SOHO Extreme UV Telescope.

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. [more]
On 6 Apr 2001 there were 299 known Potentially
Hazardous Asteroids ASTEROIDS GALORE: March was a good month for asteroid hunters. Between March 21st and 31st astronomers discovered seven Earth-approaching space rocks (click to view 3D orbits): 2001 FM129, 2001 FE90, 2001 FB90, 2001 FD58, 2001 FC58, 2001 FA58 and 2001 FO32. There is no danger of a collision with any of these asteroids. Earth-asteroid encounters (Mar 1 - Apr 30)
