The constellation Scorpius, the , is located in the southern hemisphere of the sky. It can be seen in summer from the northern hemisphere, but is low in the sky and is best seen from the southern hemisphere or southern United States. It is visible at latitudes between 40 degrees and degrees. It lies between to the west and to the east. It is a medium-sized constellation that occupies square degrees of the sky. It ranks 33rd in size among the 88 of the . Scorpius is easy to find due to its distinct "J" shape, also described as a fishhook. It is one of the thirteen constellations of the . This means it lies along the path the travels in the sky during the . Scorpius is one of the 48 constellations identified by the Greek astronomer in the second century. It is an ancient constellation that pre-dated the Greeks. It was this scorpion's sting that caused Orion's death. In another version, it was the that sent the scorpion to kill Orion after he bragged about being able to kill any wild beast. The scorpion still chases Orion across the heavens, but will never catch him because it rises in the East after Orion has set in the West. Scorpius is famous for the bright orange known as . It is the brightest star in the constellation with a visual of 0. Antares is a located approximately light from Earth. It is the 16th brightest star in the night sky and its distinctive orange glow can easily be seen in the southern sky. In a Greek myth without Orion, the celestial scorpion encountered while he was driving his father ' Sun Chariot. The Babylonians called this constellation MUL. TAB - the 'Scorpion', the signs can be literally read as 'the creature with a burning sting'. In some old descriptions the constellation of Libra is treated as the Scorpion's claws. The Western astrological sign differs from the astronomical constellation. Astronomically, the sun is in Scorpius for just six days, from November 23 to November Much of the difference is due to the constellation , which is used by few astrologers.

Gliese Cc is a "super-Earth" that is roughly four times as massive as Earth. It a red dwarf called Gliese C; the star is part of a three- that is only 22 light-years away from Earth. The is considered potentially habitable , according to the University of Puerto Rico at Arecibo's Planetary Habitability Laboratory. Notably, the same system is also host to two other potentially habitable : Gliese Ce and Gliese Cf, both of which are about 2. Among astronomers, "habitability"is often defined as a rocky world that is close enough to its parent star for liquid to exist on the surface. However, there are likely other metrics that come into play, such as the composition of a planet's atmosphere and the variability of the host star. Antares , also called alpha Scorpii, is a red supergiant and the 16th brightest star, with an between 0. It is part of a binary system, having a faint companion. Shaula , also known as , is the second-brightest star in the constellation and the 25th brightest star in the sky, with an apparent magnitude of about 1. Astronomers have confirmed it too is made up of two stars, and there could be a third one given that the star system is producing more X-rays than expected. The constellation encompasses , one of only 10 known recurring , which is the rapid increase in the brightness of a star. While it normally has a magnitude of 18, it reaches a magnitude of about 8 during outbursts, which have been observed in , , , , , and Zeta- is a hypergiant star belonging to the spectral class B1. It is approximately 2, light years distant from the . Its visual brightness ranges from magnitude 4.

Mu Scorpii is a designation shared by two star systems separated by 0. Mu-1 Scorpii is a system with a combined apparent magnitude of 3. It is classified as an eclipsing binary star of the Beta Lyrae type, with the two components periodically eclipsing each other. The primary component is a star belonging to the spectral class B1. The companion is also a class B star, type B6. Mu- is a star belonging to the spectral class B2IV. The star has a radius seven times than of the Sun. The star is located on the northern border of the constellation. It has a visual magnitude of 5. In September , astrobiologist Margaret Turnbull identified the star as one of the most promising nearby candidates for hosting life, but no planets have been discovered yet orbiting the star. Gliese is a triple star system in Scorpius. The components have visual magnitudes of 5. The two brighter components, Gliese A and Gliese B, each other with a period of When observed without a visual aid, the system appears like a single star with an apparent magnitude of 5. Gliese A is a main sequence star belonging to the spectral class K3 V, smaller and less massive than the Sun. Gliese C is a red dwarf belonging to the spectral class M1. It has two confirmed extrasolar planets in its orbit, and a third planet is a strong possibility. HD is a yellow dwarf with the G5V. It has an apparent magnitude of 7. A planet believed to be a gas giant was discovered orbiting the star in , and another extrasolar planet was discovered in Pismis is the largest star in the open cluster Pismis 24, located within the NGC It has an apparent magnitude of It is one of the most luminous stars known. Scorpius X-1 is an X-ray source in Scorpius. It is a low-mass X-ray binary system composed of a neutron star that draws material off a donor star. Scorpius X-1 was the first X-ray source discovered outside the solar system and it is the strongest source of X-rays in the sky, second only to the Sun. The X-ray flux is associated with the star V Scorpii, a blue variable which is the optical counterpart to Scorpius X Scorpius X-1 was discovered by a team led by the astrophysicist Riccardo Giacconi in Giacconi laid the foundations of X-ray astronomy and won a Nobel Prize for his work in PSR B is a binary star located approximately 12, light years away in the direction of Messier 4, a in Scorpius. The system lies just outside the cluster. An extrasolar planet was discovered orbiting the two stars in This is a image of the location of the pulsar B, which is orbited by both a and a -sized planet. Richer University of British Columbia. Wray is also one of the most luminous stars known. It is believed to be a luminous blue variable LBV , and has an of Messier 4 is a globular cluster in Scorpius. It has an apparent magnitude of 5. It was the first globular cluster discovered in which individual stars could be resolved. The brightest stars in M4 have an apparent magnitude of M4 is about 75 light years across. M4 is easy to find in the sky, as it lies 1. Along with NGC in the constellation , which is also 7, light years away, Messier 4 is the closest globular cluster to our solar system. Messier 6 is an open cluster also known as the Butterly Cluster because its stars form a shape similar to that of a butterfly. The cluster was first discovered by the Italian astronomer Giovanni Batista Hodierna in and included it in his catalogue in The bright stars in M4 are mostly hot, blue, class B stars, but the brightest one is a class K orange giant, BM Scorpii. The has an apparent magnitude of 4. Ptolemy believed the cluster to be a nebula. The Ptolemy Cluster contains about 80 stars, the brightest of which has a visual magnitude of 5. M7 is approximately light years distant from the solar system. It is roughly 25 light years in diameter. The age of the cluster is estimated to be around million years. Messier 80 is a globular cluster discovered by Charles Messier in Located about 28, light-years from Earth, M80 contains hundreds of thousands of stars, all held together by their mutual gravitational attraction. Globular clusters are particularly useful for studying , since all of the stars in the cluster have the same age about 15 billion years , but cover a range of stellar masses. Every star visible in this image is either more highly evolved than, or in a few rare cases more massive than, our own Sun. Especially obvious are the bright red giants, which are stars similar to the Sun in mass that are nearing the ends of their lives. M80 is about 95 light years in diameter and contains hundreds of thousands of stars. It is one of the most densely populated clusters in our galaxy. The cluster lies halfway between the stars Antares and Acrab. It is visible in moderate- sized amateur telescopes. It is home to a significant number of blue stragglers, blue main sequence stars that appear to be much younger because they are bluer and more luminous than stars at the main sequence turn-off point for the cluster. The progenitor star was . It is a vast star-forming region and one of the most active stellar nurseries containing some of the most massive stars known in the . It is believed to contain tens of thousands of stars. NGC lies about light-years from Earth in the constellation of Scorpius. The whole gas cloud is about 50 light-years across. NGC is one of the most active nurseries of massive stars in our galaxy and has been extensively studied by astronomers. The nebula conceals freshly minted brilliant blue stars — each nearly ten times the mass of our Sun and born in the last few million years. The region is also home to many baby stars that are buried deep in the dust, making them difficult to study. The nebula appears red because its blue and green light are scattered and absorbed more efficiently by material between the nebula and Earth. The red light comes predominantly from gas glowing under the intense glare of hot young stars. Image: ESO. NGC is a nebula about 1. It was created when a medium-sized star ran out of fuel and shed its outer envelope into space. The primary star, Girtab A, is also a variable Beta Cephei star. , also known as Fang, is a triple star system located at around light-years away from Earth, having an apparent magnitude of 2.

The Scorpius constellation has intrigued people for centuries, not only for its distinctive shape, but also because it is one of the brightest constellations in the sky. The name is Latin for scorpion , or literally translated as the "creature with the burning sting. The Javanese people of Indonesia call this constellation Banyakangrem, meaning "the brooded swan" or Kalapa Doyong, meaning "leaning coconut tree. In Chinese mythology, the constellation was part of the . In the Northern Hemisphere, Scorpius lies close to the southern horizon; in the Southern Hemisphere, it lies high in the sky near the center of the Milky Way. Scorpius used to be larger. The ancient Greeks considered the Libra constellation to be the claws of the scorpion. Scorpius happens to be the location for several interesting , who have metrics ranging from extreme old age to potential habitability. By comparison, the universe is about It's about twice Jupiter's mass and orbits around two stars, making it a . Gliese Cc is a "super-Earth" that is roughly four times as massive as Earth. It orbits a red dwarf called Gliese C; the star is part of a three-star system that is only 22 light-years away from Earth. The planet is considered potentially habitable , according to the University of Puerto Rico at Arecibo's Planetary Habitability Laboratory. Notably, the same system is also host to two other potentially habitable planets: Gliese Ce and Gliese Cf, both of which are about 2. Among astronomers, "habitability"is often defined as a rocky world that is close enough to its parent star for liquid water to exist on the surface. However, there are likely other metrics that come into play, such as the composition of a planet's atmosphere and the variability of the host star. Antares , also called alpha Scorpii, is a red supergiant and the 16th brightest star, with an apparent magnitude between 0. It is part of a binary system, having a faint companion. Shaula , also known as Lambda Scorpii, is the second-brightest star in the constellation and the 25th brightest star in the sky, with an apparent magnitude of about 1.
