We're getting some wonderfully crisp, clear winter nights now.
You know, its definitely worth getting up early and having a look around the night sky at present.
At 6am, (although its all visible until virtually 7am at present),
Venus is still gloriously bright in the south east (along with the crescent moon at the moment),
Mars is still very bright indeed, due west, slap bang next door to the star
Mebsuta in the constellation
Gemini (the Twins).
Move your eyes in the direction of 11 o'clock from the bright orange planet Mars, and you'll suddenly realise you are looking at the famous twins themselves,
Castor and Pollux, or to give them their Greek names,
Kastor ("He who excels") and
Poludeukeis ("Very sweet").
The left hand star (as you look at it) is actually
Pollux, which appears orange to the naked eye.
Castor, to the right, appears blue, though in actual fact, through a decent telescope,
Castor is revealed to be quite an incredible multiple star, comprising of six separate components.
As with virtually all these myths and legends, accounts of
Castor and Pollux do vary considerably, especially between ancient Greece and Rome.
A popular version is that these twins were the brothers of
Helen of Troy, members of
Jason's Argonaut crew (its
bound to be on tv over christmas again - great!
), and of mixed parentage - both having
Leda as their mother, but
Castor's father was
King Tyndareus of Sparta (
Castor was mortal originally) whereas
Pollux's father was the God of Gods,
Zeus himself, (
Pollux was always immortal).
Zeus seduced
Leda (and
Pollux was the immortal result) in the guise of a Swan,
Cygnus, (another constellation in the night sky) - every night sky tells a story!
The twins are certainly a very famous ancient legend, and mentioned in both
Homer's "The Iliad" (difficult to read in my opinion
) and "Odyssey", (MUCH more enjoyable!
)
The twins, since ancient times, have always been used as a very good measurement of angular distances, being exactly 4.5 degrees apart.
They are two of the patron saints of mariners, appearing in ships' rigging as the electrical phenomenon
St. Elmo's Fire (remember the 1985 film of the same name (metaphorically related I suppose) and
John Parr's number one hit? Ok. Just me then).
Don't remember (or admit to remembering!) that cheesy rock song. How about the 1997 film "Face Off", starring
Nicolas Cage and
Alessandro Nivola. These two actors if you remember, play brothers
Castor and Pollux Troy, a pair of terrorists-for-hire who are devoted to each other.
No?
Ok. Still just me then!
Do remember the twins though,
especially in December. Between the dates of the
7th and 15th December (approximately) and peaking between the 12th and the 14th, the very consistent
Geminids meteor shower will be visible in the night sky, if we are lucky enough to have clear viewing conditions.
The Geminids are caused by an object named
3200 phaethon, which is thought to be an extinct comet.
The meteors in this shower appear to come from a radiant , (a point in the sky), near
Castor, in
Gemini, (hence the shower's name). However, they can appear almost anywhere in the night sky, and often appear yellowish in colour.
The meteors travel at medium speed in relation to other showers, at about 20 miles per second, making them a little less "blink and you'll miss 'em" than other "shooting stars"!
As I said, do have a look at
Venus, Mars and
Castor and Pollux in the night sky at present, and lets hope for clear skies in middle of the month...
