ISS TOOLBAG:
When Endeavour astronaut Heidemarie Stefanyshyn-Piper dropped
her toolbag during a spacewalk on Nov. 18th and it floated away,
mission controllers probably figured they'd seen the last of it.
Think again. On Nov. 22nd, veteran satellite observer Kevin Fetter
video-recorded the backpack-sized bag gliding over his backyard
observatory in Brockville, Ontario: 900
kB video. "It was easily 8th magnitude or brighter as it
passed by the 4th magnitude star eta Pisces," he says. Spaceweather's
satellite tracker is monitoring the toolbag; click here
for flybys.
UPDATE: Ed Light of Lakewood, NJ, saw the toolbag
on the same night. He observed it using 10x50 binoculars and estimates
its magnitude at +6.4, just below the threshold of naked-eye visibility.
"It was a favorable pass, elevation 70 degrees," he notes.
"Lower apparitions would be fainter."
EXPLOSION IN PROGRESS:
An explosion is underway on the sun. The
source of the blast lies out of sight somewhere over the sun's western
limb, but the ejecta is visible as it billows into space:

A coronagraph onboard the Solar and Heliospheric Observatory
(SOHO) is monitoring the progress of the expanding CME. The cloud
is not directed at Earth and should cause no geomagnetic activity
on our planet. It is, however, a promising "sign
of life" on the sun. Slowly but surely, solar minimum is
coming to an end.
3D BEHEMOTH:
It masses 300,214 kg, has wings almost as wide as a football field,
occupies 12,626 cubic feet of living space--and now it's jumping
out of your computer screen. Put on your 3D
glasses and behold in the International Space Station:

Graphic artist Patrick
Vantuyne of Belgium created the anaglyph using photos taken
from space shuttle Endeavour on Nov. 16th. Endeavour was hovering
near the ISS for a mutual inspection prior to docking hours later.
When Endeavour did link up, it added about 110,000 kg of mass and
23 meters of wingspan to the complex. If only a third spacecraft
had been present to take photos of that....
Docked together, Endeavour and the ISS are circling Earth and flying
over many towns and cities after dark. They're bright, eye-catching,
and if you look at them through a telescope, genuinely
3D. Check the Simple Satellite Tracker
