My favorite wintertime constellation!
The longer, cooler nights of late autumn bring one of the great
skywatching treats of the year: the return of Orion to prime time
viewing hours. The hunter is in good view in the east by about 9 p.m.,
and climbs high across the south later on.
SOLAR FLEET PICKS UP COMET ISON:
Because NASA's twin STEREO probes are designed to
observe the sun, they can see sundiving comets even
when the glare becomes intense. Yesterday, Comet
ISON joined Earth, Mercury, and Comet Encke in the
field of view of STEREO-A's Heliospheric Imager. Comet ISON is plunging toward the
sun and brightening as it heads for a perilous close
encounter on Nov. 28th.
