What's up in Space
July 2, 2007
Where's Saturn? Is that a UFO--or the ISS? What's the name of that star? Get the answers from mySKY--a fun new astronomy helper from Meade.

GENESIS II: Bigelow Aerospace has launched another inflatable satellite: Genesis II. Believe it or not, the 4.4-meter wide balloon is a prototype module for a space hotel. On July 1st, satellite observer Kevin Fetter photographed Genesis II gliding past the bright star Vega: video. "Genesis was about as bright as a 3rd magnitude star--easily visible to the unaided eye," says Fetter.

SATURN-FINDER: If you've ever wanted to see the rings of Saturn, tonight is a good night to look. Venus shows the way. The two planets are side-by-side and they pop out of the twilight together at sunset:


Photo details: Canon EOS 400D, EF-S 18-55mm lens

Amateur astronomer Mohammad Javad Fahimi took this picture last night from Kerman, Iran. The telescope in the foreground, no fancier than what you might find on the shelf at a department store, is big enough to reveal not only the rings of Saturn but also the crescent shape of Venus. Got a telescope? Point it here.

X-RAY OBSERVATORY: "It was too cloudy to see Venus and Saturn last night," reports Colleen Gino of Socorro, New Mexico. "So we decided to take a picture of our telescope instead."


Photo details: Nikon D80, Sigma 10mm lens, ISO 1250, f/4.5, 35s.

"The telescope is one of many at the Etscorn Observatory on the campus of New Mexico Tech. This 'x-ray' image was created by rotating the dome with the slit open and a red light on inside."

"Thanks to Dan Klinglesmith for his help in taking the shot!" says Gino.

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 July 2, 2007 there were 874 potentially hazardous asteroids.
