SIGNS OF THE ZODIAC, SCORPIO<br />

Scorpius (Latin: <strong>Scorpio</strong>) is <strong>the</strong> eighth astrological sign in <strong>the</strong><br />

<strong>Zodiac</strong>. It spans from 210 to 240 degree <strong>of</strong> <strong>the</strong> zodiac,<br />

between 207.25 and 234.75 degree <strong>of</strong> celestial longitude, an<br />

area which <strong>the</strong> Sun transits on average between October 23<br />

and November 22 each year. Individuals born during <strong>the</strong>se<br />

dates may be called <strong>Scorpio</strong>s.<br />

Scorpius (or <strong>Scorpio</strong>) is one <strong>of</strong> <strong>the</strong> 12 constellations <strong>of</strong> <strong>the</strong><br />

zodiac. Its name is Latin for scorpion, and its symbol is<br />

It lies between Libra to <strong>the</strong> west and Sagittarius to <strong>the</strong> east. It<br />

is a large constellation located in <strong>the</strong> sou<strong>the</strong>rn hemisphere<br />

near <strong>the</strong> centre <strong>of</strong> <strong>the</strong> Milky Way. Scorpius contains many<br />

bright stars, including Antares a, Graffias ß, Dschubba δ,<br />

Sargas θ, Shaula λ, Jabbah ν, Girtab ξ, Iclil π, Alniyat σ and<br />

Lesath υ. Antares happens to lie near <strong>the</strong> ecliptic and <strong>the</strong><br />

super-giant with its reddish appearance is <strong>of</strong>ten confused<br />

with <strong>the</strong> planet Mars. Antares means <strong>the</strong> rival <strong>of</strong> Mars.<br />

Along with Aldebaran, Spica, and Regulus it is one <strong>of</strong> <strong>the</strong><br />

four brightest stars near <strong>the</strong> ecliptic. The bright stars <strong>of</strong><br />

<strong>Scorpio</strong> form a pattern like a baling hook. Maori mythology<br />

sees it as a fishing hook.<br />

Most <strong>of</strong> <strong>the</strong> bright stars are massive members <strong>of</strong> <strong>the</strong> nearest<br />

OB association Scorpius-Centaurus, some 400 light years<br />

from <strong>the</strong> Sun. These associations are believed to form within a<br />

small volume inside a giant molecular cloud. Once <strong>the</strong><br />

surrounding dust and gas is blown away <strong>the</strong> remaining stars<br />

become unbound and begin to drift apart. It is believed that <strong>the</strong><br />

majority <strong>of</strong> all stars in <strong>the</strong> Milky Way were formed in OB<br />

associations. ?O” class stars are short-lived, and will expire as<br />

supernovae after roughly a million years. As a result, OB<br />

associations are generally only a few million years in age or less.<br />

They will burn all <strong>the</strong>ir fuel within 10 million years.<br />

(Compare this to <strong>the</strong> current age <strong>of</strong> <strong>the</strong> Sun at about 5 billion<br />

years.) Remember, we talked earlier about <strong>the</strong> system <strong>of</strong><br />

classifying <strong>the</strong> stars by <strong>the</strong>ir intrinsic temperature (colour) using<br />

<strong>the</strong> letters O, B, A, F, G, K, M and N, where O stars are <strong>the</strong><br />

hottest (Blue Giants) and <strong>the</strong> coolest <strong>the</strong> N class (Red Dwarfs).<br />

A useful mnemonics for remembering <strong>the</strong>se spectral type letters<br />

is "Oh Be A Fine Girl Kiss Me Now". This, by <strong>the</strong> way, is not<br />

necessarily <strong>the</strong> colour we see <strong>the</strong>m, as obscuring dust can <strong>of</strong>ten<br />

affect <strong>the</strong> colour seen.<br />

The star delta Sco, after having been a stable 2.3 magnitude star<br />

for centuries, flared in July 2000 to 1.9 in a matter <strong>of</strong> weeks. It<br />

has since become a variable star, fluctuating between 2.0 and<br />

1.6. This means that at its brightest it is <strong>the</strong> second brightest star<br />

in Scorpius. Lambda Sco and upsilon Sco, two stars at <strong>the</strong> end<br />

<strong>of</strong> <strong>the</strong> scorpion's tail that appear very close toge<strong>the</strong>r, are<br />

Scorpius as depicted in Urania's Mirror, a set <strong>of</strong><br />

constellation cards published in London c.1825<br />

sometimes referred to as <strong>the</strong> Cat's Eyes. The ancient Greek version <strong>of</strong> Scorpius was much larger than <strong>the</strong><br />

constellation we know today. The Greek scorpion was in two halves: one half contained its body and sting,<br />

while <strong>the</strong> front half comprised <strong>the</strong> claws. The Greeks called this front half Chelae, which means ‘claws’. In <strong>the</strong><br />

first century BC <strong>the</strong> Romans made <strong>the</strong> claws into a separate constellation, Libra, <strong>the</strong> Balance. The<br />

Babylonians called this constellation '<strong>the</strong> creature with a burning sting' and saw <strong>the</strong> claws already as <strong>the</strong> Scales.<br />

Due to its location on <strong>the</strong> Milky Way, this constellation contains many deep-sky objects such as <strong>the</strong> open<br />

clusters Messier 6 (<strong>the</strong> Butterfly Cluster) and Messier 7 (<strong>the</strong> Ptolemy Cluster), NGC 6231 and <strong>the</strong> globular<br />

clusters Messier 4 and Messier 80. Messier 80 (NGC 6093) is a globular cluster <strong>of</strong> magnitude 7.3, 33,000


light-years from Earth. It is a<br />

compact Shapley class II cluster;<br />

<strong>the</strong> classification indicates that it<br />

is highly concentrated and dense<br />

at its nucleus. M80 was<br />

discovered in 1781 by Charles<br />

Messier. It was <strong>the</strong> site <strong>of</strong> a rare<br />

discovery in 1860 when Arthur<br />

von Auwers discovered <strong>the</strong> nova<br />

T Scorpii. It had not been since.<br />

Recently, astronomers studying<br />

stellar populations in M80 in <strong>the</strong><br />

ultraviolet, using <strong>the</strong> HST, were<br />

able to identify most <strong>of</strong> <strong>the</strong><br />

known x-ray sources in <strong>the</strong> core<br />

<strong>of</strong> <strong>the</strong> cluster. While <strong>the</strong> main<br />

point <strong>of</strong> <strong>the</strong>ir investigation was to study <strong>the</strong> populations <strong>of</strong> Blue Straggler Stars, one <strong>of</strong> <strong>the</strong>se sources happened<br />

to be a dwarf nova in outburst at <strong>the</strong> time <strong>of</strong> <strong>the</strong> observations. More interesting than that, it appears to be<br />

consistent with <strong>the</strong> location <strong>of</strong> <strong>the</strong> 1860 nova, T Scorpii. Given its position, X-ray and UV brightness and<br />

variability, this source is almost certainly <strong>the</strong> true counterpart to T Sco. After 150 years an old friend was<br />

finally found again.<br />

In Greek Mythology <strong>the</strong> myths associated with<br />

<strong>Scorpio</strong> almost invariably also contain a reference to<br />

Orion. According to one <strong>of</strong> <strong>the</strong>se myths it is written<br />

that Orion boasted to goddess Artemis and her<br />

mo<strong>the</strong>r, Leto, that he would kill every animal on <strong>the</strong><br />

earth. Although Artemis was known to be a hunter<br />

herself she <strong>of</strong>fered protection to all creatures.<br />

Artemis and her mo<strong>the</strong>r Leto sent a scorpion to deal<br />

with Orion. The pair battled and <strong>the</strong> scorpion killed<br />

Orion. However, <strong>the</strong> contest was apparently a lively<br />

one that caught <strong>the</strong> attention <strong>of</strong> Zeus, who <strong>the</strong>n raised<br />

<strong>the</strong> scorpion to heaven and afterwards, at <strong>the</strong> request<br />

<strong>of</strong> Artemis, did <strong>the</strong> same for Orion to serve as a<br />

reminder for mortals to curb <strong>the</strong>ir excessive pride. So<br />

every winter Orion hunts in <strong>the</strong> sky, but every<br />

summer he flees as <strong>the</strong> constellation <strong>of</strong> <strong>the</strong> scorpion<br />

rises.<br />

In ano<strong>the</strong>r Greek story involving <strong>Scorpio</strong> without<br />

Orion, Phaeton (<strong>the</strong> mortal male <strong>of</strong>fspring <strong>of</strong> Helios)<br />

went to his fa<strong>the</strong>r, who had earlier sworn by <strong>the</strong> River<br />

Styx to give Phaeton anything he should ask for.<br />

Phaeton wanted to drive his fa<strong>the</strong>r's Sun Chariot for a day.<br />

Although Helios tried to dissuade his son, Phaeton was<br />

adamant. However, when <strong>the</strong> day arrived, Phaeton panicked<br />

and lost control <strong>of</strong> <strong>the</strong> white horses that drew <strong>the</strong> chariot.<br />

First, <strong>the</strong> Earth grew chill as Phaeton flew too high and <strong>the</strong>re<br />

encountered <strong>the</strong> celestial scorpion, its deadly sting raised to<br />

strike. Alarmed, he dipped <strong>the</strong> chariot too close to <strong>the</strong> Earth,<br />

causing <strong>the</strong> vegetation to burn. By accident, Phaeton turned<br />

most <strong>of</strong> Africa into desert and darkened <strong>the</strong> skin <strong>of</strong> <strong>the</strong><br />

Ethiopian nation until it was black. Eventually, Zeus was<br />

forced to intervene by striking <strong>the</strong> runaway chariot and<br />

Phaeton with a lightning bolt to put an end to its rampage and<br />

Phaeton plunged into <strong>the</strong> River Eridanos. AK<br />

Scorpius from <strong>the</strong> Uranographia <strong>of</strong> Johann Bode (1801). Part <strong>of</strong> <strong>the</strong><br />

scorpion’s body is overlapped by <strong>the</strong> foot <strong>of</strong> Ophiuchus. In <strong>the</strong><br />

middle <strong>of</strong> <strong>the</strong> scorpion’s body lies <strong>the</strong> red star Antares. On this chart,<br />

Bode also gives Antares <strong>the</strong> alternative name Calbalacrab, from <strong>the</strong><br />

Arabic meaning ‘scorpion’s heart’
