What's up in Space
April 9, 2008
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.   mySKY

SOYUZ AND MIZAR: A new crew for the International Space Station blasted off from the Baikonur Cosmodrome in Kazakhstan on Tuesday morning, April 8th. Hours later, Kevin Fetter photographed their Soyuz spacecraft passing by the star Mizar en route to the ISS: video. "It was a nice bright flyby," he says. "I'm glad I got to see it." The Soyuz is due to reach the ISS and dock to the busy station on Thursday, April 10th.

AURORA WATCH: "Last night, I was out trying to photograph an igloo in the evening twilight, when all of a sudden an explosion of light danced overhead," reports Claus Vogel on Baffin Island, Canada. "I have never seen the aurora so bright at dusk - and what timing. I had my Nikon D300 and tripod ready when the lights began their northern dance."

"I have always dreamed of this. Woweee!!"

Similar displays are in the offing tonight. A solar wind stream is buffeting Earth's magnetic field and causing intermittent geomagnetic storms. Northern sky watchers, be alert for auroras.

SIDNEY'S CONJUNCTION: Last night's conjunction of the crescent Moon and the Pleiades was tail-wagging beautiful. Literally. "My friend's dog, Sidney, decided that wagging her tail against my tripod was a great idea," says photographer Greg Scheckler of North Adams, Massachusetts. Here is the result:

"Happy accident or strange goof," he says, "we now have an abstract picture of Luna with the Seven (or three hundred!) Sisters."

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. [comment]
On April 9, 2008 there were 946 potentially hazardous asteroids.
