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

DOUBLE SOLAR ECLIPSE: Not satisfied with an ordinary blow-your-socks-off partial eclipse (see below), celebrated photographer Thierry Legault traveled to the Sultanate of Oman to record a rare double eclipse. For a split-second on Jan. 4th the disk of the sun was partially covered by the Moon and the International Space Station: must-see photos.

CRESCENT SUNRISE: Earlier today, the new Moon passed in front of the sun, slightly off-center, producing a partial solar eclipse and a fantastic crescent sunrise over Europe. Dennis Put sends this picture from Maasvlakte, The Netherlands:

"The eclipse was absolutely stunning!" says Put. "At first some major cloud fronts threatened to hide the event. I was very pleased to meet the two peaks of the crescent Sun rising above the clouds around 9 o'clock."

Kuure of Tampere, Finland; from Luke Broom-Lynne of Norfolk, United Kingdom; from Philippe Van den Doorn of Rixensart, Belgium; from Andrea Aletti of S.Maria del Monte (VA) Italy; from Rob Kantelberg of Sint Oedenrode, The Netherlands; from Robbert-Jan Westerduin of Nijmegen, The Netherlands

Stay tuned for (lots) more photos.

AURORAS AND METEORS: "Wow!" exclaims Fredrik Broms of Kvaløya, Norway. "[Last night], Earth's upper atmosphere got hit full force both by the solar wind, producing some amazing coronas in purple and green, and every now and then by a fragment from shattered comet 2003 EH1, source of the Quadrantid meteor shower." He took this picture using his Nikon D3:

"Bitter cold weather here in northern Norway made the photo-session a bit shorter than I hoped--indeed, my lens was completely covered in ice crystals--but I managed to catch some of the beauty of this cold night," says Broms.

  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 January 4, 2011 there were 1167 potentially hazardous asteroids.
