First Census of Galaxies Near Cosmic
Dawn
The Night Sky
Friday, December 14
· Orion stands centered between two bright lights this
year. High above it during evening shines dazzling
Jupiter (with its orange sidekick Aldebaran). A similar
distance below Jupiter, Sirius rises around 8 p.m. (the
time depends on your location), with its own sidekick,
Mirzam.
· Sirius, just 8.6 light-years away, is the brightest star
in the night sky. It's also the closest star beyond the
Sun that's ever visible to the unaided eye from midnorthern latitudes.
· Algol in Perseus should be at minimum light for a
couple hours centered on 6:07 p.m. EST. Watch it
rebrightening for much of the rest of the night.
· Jupiter's Great Red Spot should cross Jupiter's
central meridian around 8:22 p.m. EST. For all of the
Great Red Spot's transit times, as well as all of
Jupiter's satellite events, get the new JupiterMoons
app!
Saturday, December 15
· In early evening, the "Summer Star" Vega is still the
brightest thing in the northwestern sky, though it's
moving ever lower. The brightest above it is Deneb.
Vega is 25 light-years away; supergiant Deneb is
about 1,400.
The Night Sky
Sunday, December 16
· Jupiter's moon Io crosses Jupiter's face from 8:19 to
10:29 p.m. EST, closely followed by its tiny black
shadow (much plainer to see in a telescope) from 8:41
to 10:52 p.m. EST. Meanwhile, the Great Red Spot
should cross Jupiter's central meridian around 10:00
p.m. EST. To track all of Jupiter's satellite events and
the Great Red Spot's transit times, get the new
JupiterMoons app.
Monday, December 17
· The first-discovered asteroid, 1 Ceres, is at
opposition tonight. It's not far from 4 Vesta, which is
also in Taurus along with Jupiter. Ceres and Vesta are
now magnitudes 6.7 and 6.5, respectively. Spot them
in binoculars near the horns of Taurus using the finder
chart in the December Sky & Telescope, page 50, or
online.
