Saturday: “Hey baby! What’s your sign?”
“Ophiuchus,
of course”
The Sun is
in the same part of the sky as the stars of Ophiuchus from about November 29 to
December 17. This is what astrologers mean when they say the Sun is “in” a
constellation. Thus, if you were born between these dates, you should be an
Ophiuchus. The fact that the horoscopes never list Ophiuchus is a major flaw of
astrology. Astrology says that some of our characteristics are based on the
location of the Sun at our birth. How can astrologers leave out three weeks from
their system? That is like a scientist saying she can explain the results of
her experiment every month of the year except early December. Ophiuchus was a
mythical healer who was a forerunner to Hippocrates. According to myth, he
could raise people from the dead. Maybe that is why he is ignored by astrology.
Raising people from the dead is much less impressive than giving spot-on advice
such as “Today is a good day to watch your finances.”
The bright
stars of Ophiuchus rise just before the Sun. Rasalhague (pronounced
Ras’-al-hay’-gwee), the brightest star, is about a half a fist held upright and
at arm’s length above the east-northeast horizon at 6:30 a.m.
Sunday: Mercury
and Saturn are staring at you, just above the southwest horizon at 4:45 p.m.
Mercury is just to the right of due southwest and Saturn is a little more than
a half a fist to the right of Mercury.
Monday: Have
you been shopping all weekend? Do you need an evening sky break? You deserve a
big reward so make it a double. A Double Cluster, that is. The Double Cluster,
also known as h and Chi Persei, consists of two young open star clusters in the
constellation Perseus. Of course, young is a relative term as these clusters
are about 13 million years old. Each cluster is spread out over an area about
the same size as the full moon. To the naked eye, the Double Cluster shines
with a steady, fuzzy glow. Binoculars resolve dozens of individual stars in the
clusters. The Double Cluster is six fists above the northeast horizon at 6
p.m., about a fist below the sideways “W” of Cassiopeia and three fists above
the bright star Capella.
Tuesday:
Have you even seen a Black Hole? Neither have scientists. But they have seen
the effects of a Black Hole. Black holes have a strong gravitational influence
on anything that passes close to them, including light. Cygnus X-1, the first
Black Hole candidate ever discovered, is six fists above the west horizon at 7
p.m., in the middle of the neck of Cygnus the swan. NASA launched the Chandra
X-ray observatory in 1999 to study black hole candidates and other high-energy
events.
Wednesday: I am guessing that some of you don’t like the line of reasoning
from Tuesday: that seeing the effects of a Black Hole is good enough to claim
there are Black Holes. You have never seen the wind. But, you have seen the
effects of the wind. And no Ellensburg resident doubts the existence of the
wind.
Thursday: Is your favorite astronomy-loving relative of yours asking for a
telescope this Christmas? Before reaching for your credit card, read this guide
to choosing your first telescope, available at http://goo.gl/5oXmGj. If cost is an issue,
look no further than this Sky and Telescope article about low cost telescopes http://goo.gl/40zd6.
The authors review and recommend three telescopes that now cost less than $130
each. If you want to give a gag astronomy gift to someone who really bugs you,
give them a copy this column. After such a dud “gift”, you’ll never hear from
them again. And that may be the best gift of all.
Friday: Venus
is one and a half fists above the south-southwest horizon at 5 p.m., just to
the lower left of the young crescent Moon.
The
positional information in this column about stars and planets is typically
accurate for the entire week. For up to date information about the night sky,
