Constellation of the Month: Scorpius (the Scorpion)

If you happen to be a follower of that nonscientific field of soothsaying known as astrology, you already know that Scorpio is a sign of the Zodiac, representing people born October 23-November 21...guess what, I think horoscopes are a lot of hooey.  Astronomically speaking, I learned about the celestial Zodiac constellation Scorpius early in life at the age of seven...I remember that late spring night 56 years ago when I got permission to stay up late enough to watch it rise in the southeastern sky, leading with the scorpion's claws (three stars) followed by its highlight, the bright red giant star Antares.  In the United States Scorpius passes low in the southern sky during summer evenings and actually does resemble a scorpion when you connect together the dots (its stars, that is).  It also lies on the elliptic, meaning that our sun, moon, and the planets are seen from our vantage point on Earth to travel through it (and the other 11 Zodiac constellations).  Now to call Scorpius a "July" constellation only means that round 9-10 pm in the evening of that month it crosses the meridian (the imaginary line in the sky that divides east from west).  I could technically call just about any of the 88 official constellations as belonging to July since they all likewise cross that meridian line, most of them at other times of the day or night, however.  So for convention's sake I do as others do and take a mental snapshot of the sky at mid-evening during a particular month...

Although Scorpius is traditionally represented by that scorpion pattern from its brightest visible stars, the constellation is actually a sector of space projected outward from Earth to the farthest regions of the universe, comprising untold numbers of galaxies.  There are four Messier "objects" with Scorpius, all star clusters.  Scorpius lies the furthest south of all the Zodiac constellations, passing low in continental American skies.  It's usually a lot easier to notice the three prominent "claw" stars at the constellation's western end, followed by spectacular Antares.  The upper two claw stars are Graffius and Dschubba, respectively.  Other notable stars in Scorpius are Sargas in its tail and Shaula at the tip where the "stinger" is...

I have a memory from childhood of being with my family at the Golden Glades Drive-In theatre in northern Dade County, between Opa-Locka and Carol City near the Palmetto Expressway.  We were walking outside and I happened to look up toward the south and saw Scorpius in its completeness...it's one of the more spectacular constellations in the sky, definitely the highlight of the summer season...
