What's up in Space
November 29, 2008
NORTHERN LIGHTS: Did you sleep through the auroras of November? Next time get a wake-up call: Spaceweather PHONE.  

NOT-A-SUNSPOT: A large, diffuse magnetic dipole is emerging in the sun's northern hemisphere: map. It's too spread out to form a sunspot, but it may prove interesting nevertheless. In the neutral folds of such regions, dark filaments of plasma are known to form and sometimes erupt. If you have a solar telescope, take a look.

TWO SPACESHIPS: How often do you look through the eyepiece of your telescope and see two spaceships? It happened last night to Janusz Krysiak when space shuttle Endeavour and the International Space Station flew over his backyard observatory in Koluszki, Poland:

Endeavour undocked from the ISS on Nov. 28th and it is scheduled to land in Florida on Sunday, Nov. 30th. In the meantime, many sky watchers will be able to see the two flying together through the night sky. Endeavour is about as bright as Jupiter, while the ISS shines like Venus--you can't miss them. Check the Simple Satellite Tracker for flyby times.

SUNSET PLANETS: When the sun goes down tonight, step outside and look southwest. Venus and Jupiter are having a stunning close encounter in the twilight sky. Paulo Casquinha sends this picture taken just hours ago from Langkawi, Malaysia:

"The planets were shining over the main telescope of Langkawi National Observatory," says Casquinha. "We made the dome 'transparent' by intentionally rotating it during the exposure."

This beautiful view is about to improve. On Nov. 30th and Dec. 1st, the crescent Moon will leap up from the horizon, joining Jupiter and Venus in a three-way conjunction that some astronomers are calling "the best sky show of the year." Don't miss a single night: Nov. 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 29, 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.
