Saturday: Imagine
Opie and Andy Taylor walking down the dirt path at night to that fishing hole
in the sky. They’d probably be looking to catch Pisces, the two fish already
conveniently tied together with two ropes. The ropes are connected at the star
Alrescha, Arabic for “the cord”. Alrescha is four fists held upright and at
arm’s length above due south at 10:30 p.m. The fish are attached to lines of
stars that branch out at one o’clock and three o’clock from Alrescha. By the
way, “The Fishing Hole”, The Andy Griffith Show’s theme song, was rated the 20th
best TV theme song of all time by ign.com. That’s too low of a rating in my
opinion.
Sunday: While
Stonehenge is an ancient burial ground visited by religious people for
thousands of years, MIThenge is an 825-foot long hallway on the campus of the
Massachusetts Institute of Technology visited by the Sun’s rays twice a
year. Every year in November and
January, the setting Sun lines up with a narrow window at the end of the long
hall and the light shines down to the opposite end. This season’s alignment is
from November 10-13. For more information, visit http://goo.gl/0hwFQf

Monday: We
wish you a Merry Martinmas. We wish you a Merry Martinmas. We wish you a Merry
Martinmas. And a happy Monday. Martinmas is a holiday in many parts of the
world commemorating Saint Martin of Tours. He was buried on November 11, 397.
What does this have to astronomy? Not much except that the celebration on
November 11 often doubles as a cross-quarter day celebration, a day that is
halfway between an equinox and a solstice.
Tuesday: The
Northern Taurid meteor shower peaks the next two nights. The best time to
observe this shower is mid evening before the moon rises at about 9 p.m. Under
the best conditions, you can expect about 10 meteors an hour with some of them
being bright fireballs. A few weeks ago, the related Southern Taurid meteor
shower produced many fireball sightings in the southwest United States. Meteor
showers are named after the constellation from which the meteors appear to
originate. These meteors appear to come from a point in Taurus the bull, near
the open star cluster called the Pleiades. This point is about three fists above
the east horizon at 8 p.m. You can follow this point throughout the night, as
it will remain one fist above the V-shaped Hyades Cluster with its bright star
Aldebaran (pronounced Al-deb’-a-ran). Meteors are tiny rocks that burn up in
the atmosphere when the Earth runs into them. These rocks are broken off parts
of Comet 2P/Encke.
Wednesday:
Mars is one fist above the southwest horizon at 6 p.m., just above the setting
teapot asterism. An asterism is a recognizable pattern of stars in the night
sky. The Big Dipper is probably the best-known asterism.
Thursday: Jupiter
is one fist above the east-northeast horizon at midnight.
Friday: Lieutenant
Worf, the Klingon Starfleet officer on Star Trek: The Next Generation, might
say “Today is a good day to die.” But Deneb, the bright supergiant star in Cygnus
the Swan would say “two million years from now is a good day to die.” This may
seem like a long time. But, compared to most stars, two million years from now
is as close as today. For example, the Sun will last about five billion years. Small
stars known as red dwarfs may last trillions of years. Prepare your
astronomically short good byes to Deneb tonight at 8 o’clock when it is six
fists above the west horizon.
