Scorpius

Look at the night sky.

You can see a group of stars. It looks like a big bug. This shape is called Scorpius.

It has many bright stars. One star is very red. It is called Antares. Other stars make a long tail. The tail ends with a sting. Some people say the stars look like a hook. It sits near the bright path of stars in space. It is a very old shape in the sky.

Scorpius is a group of stars in the southern sky.

It sits near the bright Milky Way. This group of stars is very old. A Greek scientist named Ptolemy listed it long ago. The stars make a shape like a long hook.

Many bright stars live here. Antares is a very famous star. It has a red color. Its name means "rival of Mars."

Some stars change how bright they look. The star delta Sco is a variable star. This means its brightness goes up and down. Another star, AH Scorpii, is a red supergiant. It is huge! It is 1,400 times larger than our Sun.

Scorpius also has deep-sky objects. These are things far away in space. You can find the Butterfly Cluster here. There is also the Cat's Paw Nebula.

Many cultures saw different shapes in these stars. In Hawaii, people saw a big fishhook. Bugis sailors used the stars to find their way. They called parts of it "skate stars" and "shark stars."

Scorpius is a famous group of stars in the southern sky.

It sits near the center of the Milky Way galaxy. This group is located between the constellations Libra and Sagittarius. Many people find it interesting because it is an ancient pattern. A Greek astronomer named Ptolemy listed it in the second century. The stars form a shape like a long hook.

This pattern helps people find their way through the night sky.

Many bright stars live within this constellation. One very famous star is Antares, which is also called alpha Scorpii. Its name means "rival of Mars" because it has a reddish color. The star delta Scorpii is a variable star. This means its brightness changes over time. In July 2000, it flared and became much brighter. It now moves between different levels of brightness. These stars are often part of a large group called the Scorpius–Centaurus Association.

Some stars in Scorpius are truly enormous. The star AH Scorpii is a red supergiant. It is 1,400 times larger than our Sun. It is also 340,000 times brighter than the Sun. However, it is too faint to see without a telescope. There is also a pair of stars called omega 1 and omega 2 Scorpii. They look like a double star to the eye. One is a yellow giant and the other is a blue star.

Scorpius also contains many deep-sky objects. These are beautiful shapes far away in space. You can find the Butterfly Cluster, which is Messier 6. There is also the Cat's Paw Nebula.

One cluster is called Messier 80. Charles Messier discovered it in 1781. It is very dense and sits 33,000 light-years away. These objects show us how much is hidden in the dark sky.

Different cultures have seen different things in these stars. In Hawaii, the stars look like a big fishhook. The Javanese people see a leaning coconut tree. Ancient Greeks told stories about a scorpion and a hunter named Orion. They believed the gods put them in the sky. Bugis sailors used the stars to help them sail. They called the northern stars "skate stars" and the southern stars "shark stars." This shows how stars connect all people.

Scorpius is a major zodiac constellation located in the southern celestial hemisphere.

It sits near the center of the Milky Way galaxy. This placement puts it between the constellations Libra to the west and Sagittarius to the east. Astronomers recognize Scorpius as an ancient pattern. It was one of the 48 constellations identified by the Greek astronomer Ptolemy in the second century. The stars in this group form a shape resembling a longshoreman's hook. Many of these stars are massive members of the Scorpius–Centaurus Association. This is a nearby group of stars that are physically related to one another.

Many bright stars define the shape of the scorpion. The most famous is Antares, also known as alpha Scorpii. Its name means "rival of Mars" because of its distinct reddish hue. Other notable stars include beta 1 Scorpii, which is a triple star system. Delta Scorpii is a variable star, meaning its brightness changes over time. In July 2000, it flared from a magnitude of 2.3 to 1.9 in just a few weeks. It now fluctuates between 2.0 and 1.6. This makes it the second brightest star in the constellation at its peak.

Some stars in Scorpius are truly massive and powerful. AH Scorpii is a red supergiant and one of the largest known stars. It is 1,400 times larger than our Sun. It is also incredibly luminous, shining 340,000 times brighter than the Sun. However, it is too faint for the naked eye to see, with a brightness between 6.5 and 9.6. There is also an optical double called omega 1 and omega 2 Scorpii. These two stars appear close together to the unaided eye. One is a yellow giant, while the other is a blue B-type star.

Because Scorpius straddles the Milky Way, it contains many deep-sky objects.

These include open clusters like Messier 6, known as the Butterfly Cluster. Messier 7 is another famous cluster called the Ptolemy Cluster. There are also globular clusters like Messier 4 and Messier 80. Messier 80 is a very dense, compact cluster located 33,000 light-years from Earth. Charles Messier discovered it in 1781. The constellation also holds nebulae. The Bug Nebula is a bipolar planetary nebula called NGC 6302. The Cat's Paw Nebula, or NGC 6334, is an emission nebula where new stars are forming.

History and mythology provide many different views of these stars. In Greek myths, the scorpion is often linked to the hunter Orion. One version says the goddess Artemis sent a giant scorpion to kill Orion after he boasted he could kill every animal. Another version says Apollo sent the scorpion. After the battle, Zeus raised both Orion and the scorpion to the sky. This serves as a reminder to mortals to avoid excessive pride. In other Greek myths, the scorpion encountered Phaethon while he drove the Sun Chariot.

Different cultures throughout history have interpreted the stars of Scorpius in unique ways. The Babylonians called the constellation MUL.GIR.TAB, which means "the scorpion." They described it as having a "burning sting." In Hawaii, the stars are known as the Big Fishhook of Maui, or Ka Makau Nui o Māui. The Javanese people of Indonesia call it the leaning coconut tree. Bugis sailors used the constellation for navigation by dividing it into two parts. They called the northern stars "skate stars" and the southern stars "shark stars." This shows how stars served different practical needs across the globe.

Scorpius also has interesting connections to modern science and astrology. In Western astrology, the sign Scorpio is different from the astronomical constellation. Astronomically, the Sun is only within the boundaries of Scorpius for six days, from November 23 to November 28. This difference exists because of the constellation Ophiuchus. In Hindu astronomy, Scorpius corresponds to the nakshatras known as Anuradha, Jyeshtha, and Mula. Even the flag of Brazil uses Scorpius to represent its Northeast region.
