The Scorpius constellation is one of the most fascinating and mesmerising constellations in the night sky. Located in the southern hemisphere, it is visible from many parts of the world, including Ireland. With its distinctive shape, it has been the subject of myths and legends for thousands of years.
In this article, we will delve into the wonders of the Scorpius constellation, its mythology, stars, and how to view it from Ireland.
The Mythology of Scorpius
Scorpius is a constellation with a rich history of mythology. According to Greek mythology, the constellation represents the scorpion that killed Orion, a great hunter. The story goes that Orion boasted to Artemis, the goddess of hunting, that he could kill all the animals on Earth. In response, Gaia, the Earth goddess, sent a giant scorpion to kill Orion.
The two battled fiercely until the scorpion eventually won and killed Orion. Zeus then placed both the scorpion and Orion in the heavens as constellations.
The Stars of Scorpius
The Scorpius constellation is home to several bright stars, including Antares, the brightest star in the constellation. Antares is a red supergiant star, 700 times larger than our sun and 10,000 times brighter.
Another notable star in the constellation is Shaula, the second brightest star. It is a blue-white star that is 20,000 times brighter than our sun and approximately 26 times larger.
Scorpius also contains several other stars, including Dschubba, Graffias, and Jabbah, all of which are easily visible in the night sky.
How to View Scorpius from Ireland
Scorpius is a southern hemisphere constellation, which means it is not visible from Ireland all year round. The best time to view Scorpius from Ireland is during the summer months, between June and August.
During this period, Scorpius is visible in the southern part of the sky, low on the horizon. To view Scorpius, you should find a location with an unobstructed view of the southern horizon.
The best time to view Scorpius is during the late evening and early morning hours when the constellation is at its highest point in the sky. You can also use a star chart or a stargazing app to locate Scorpius and identify its stars and features.

The mythology of the constellation of Scorpius
The mythology of the constellation of Scorpius is steeped in ancient Greek lore. In Greek mythology, Scorpius represents the scorpion that killed Orion, a legendary hunter. The story goes that Orion boasted to Artemis, the goddess of hunting, that he could kill all the animals on Earth. In response, Gaia, the Earth goddess, sent a giant scorpion to kill Orion.
The scorpion and Orion battled fiercely, but the scorpion eventually won and killed Orion. Zeus, the king of the gods, placed both the scorpion and Orion in the heavens as constellations.
The placement of Scorpius near Orion in the sky is no coincidence. According to the myth, Zeus placed the two constellations at opposite ends of the sky to prevent any further conflict between the scorpion and Orion. In some versions of the myth, Scorpius is said to be guarding the entrance to the underworld.
Interestingly, Scorpius is not the only constellation associated with scorpions in mythology. The Babylonians also had a scorpion constellation, which they called MUL.GIR.TAB, and the ancient Egyptians had a scorpion goddess, Serket.
In addition to its Greek mythology, Scorpius also has ties to other cultures. In Hindu mythology, the constellation is associated with Jyeshtha, a goddess of misfortune and calamity. In ancient Babylon, the constellation was known as Girtab, which means “the scorpion”. The ancient Maya also had a scorpion constellation, which they called Sip.
Overall, the mythology of the constellation of Scorpius has deep roots in ancient cultures and is a fascinating reminder of how our ancestors looked up at the same sky and saw stories and legends in the stars.
