What's up in space
 

Metallic photos of the sun by renowned photographer Greg Piepol bring together the best of art and science. Buy one or a whole set. They make a stellar gift.

 
Metallic pictures of the Sun

PARTIAL ECLIPSE OF THE STRAWBERRY MOON: On Monday, June 4th, the Moon will pass through the shadow of Earth, producing a partial lunar eclipse visible across the Pacific from China to the United States. Get the full story from Science@NASA.

LIMB SHOTS: The sun's southeastern limb is hopping with activity. New sunspot AR1492, which just rotated onto the Earthside of the sun, is crackling with C-class solar flares and hurling plumes of plasma off the stellar surface. Click on the image to set the scene in motion:

NASA's Solar Dynamics Observatory recorded the movie during the late hours of May 25th. According to the 3D Sun app, another active region is approaching just behind this one and could boost solar activity even more when it emerges in the days ahead. Stay tuned.

ECLIPSE SUNBEAMS: For many observers, the best part of the May 20th solar eclipse is not what the Moon did to the sun, but rather what it did to the sunbeams. Gaps in clouds, leafy trees, and window shades cast pinhole images of the smiling crescent sun onto all kinds of happy surfaces:

"My daughter Antonia was sitting in just the right place," says Tino Hammid of Los Angeles, California. "The crescent images are created by small holes in the closed window blinds that act as a series of pinhole cameras."

Many more pictures of the eclipse--from the sun to sunbeams--may be found in our new realtime photo gallery. It's an experimental service, so feel free to report problems. Click on the link below and start exploring:

  Near Earth Asteroids
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 May 26, 2012 there were 1293 potentially hazardous asteroids.

Notes: LD means "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.
