What's up in Space
November 27, 2008
NORTHERN LIGHTS: Did you sleep through the auroras of November? Next time get a wake-up call: Spaceweather PHONE.  

ISS TOOLBAG: NASA's runaway toolbag dropped from the International Space Station on Nov. 18th can be seen through binoculars as it orbits Earth. Europeans are favored with a series of flybys in the nights ahead. The backpack-sized bag is drifting away from the ISS and it now leads the station by about eight minutes. Check the Simple Satellite Tracker for flyby times.

THANKSGIVING SUN: This morning Greg Piepol of Rockville, Maryland, looked through the eyepiece of his backyard solar telescope and observed a very curious sunspot:

"Happy Thanksgiving!" says Piepol. "I must have been thinking about dinner because when I did a double-take the turkey was gone." The real Thanksgiving sun is pictured here. A new sunspot is forming near the center of the sun's disk but it has not yet formed a dark turkey-core. Stay tuned for updates.

SUNSET PLANETS: When the sun sets tonight, go outside and look southwest. Venus and Jupiter are beautifully close together in the twilight sky. Konstantinos Christodoulopoulos sends this picture taken just hours ago from Athens, Greece:


Photo details: Canon EOS 300D, 2 sec, ISO 200

Readers, if you think this is pretty, just wait. The two worlds are converging for a spectacular conjunction with the Moon on Dec. 1st. Some astronomers are calling it the "sky show of the year." Don't miss it! Sky maps: Nov. 27, 28, 29, 30, Dec 1.

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 November 27, 2008 there were 1002 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.
