Scorpius
is one of the most southern constellations that we can see. Because of
our northern location on the Earth, we can only see the scorpion during
the summer months. It's long curving tail touches the
southern
horizon. The bright reddish star Antares marks the heart of the scorpion.
The name Antares is Arabic for "Mar's rival" because it looks almost identical
to Mars.
Located only 1.5 degrees west of Antares is M4, one of the largest and
brightest globular clusters in the sky. Use binoculars to spot this gem.
The scorpion holds an infamous place in Greek mythology as the slayer
of the mighty hunter Orion. As Orion sets in the west each spring, Scorpius
rises in the east.
The scorpion was also responsible for the death of Phaeton, son of Apollo,
who tried to drive his father's sun-chariot across the sky. (see
Cygnus, July, 2000). Scorpius once had claws, but they were cut off
by Julius Ceasar to form the constellation Libra, located just west of
Scorpius. Scorpius also looks like the letter J.
