Scorpius, the scorpion has a shape that even those people with no imagination at all can see. Located near the brightest section of the Milky Way, when Scorpius sits low in the Southwest it appears the creature is being punished by hot boiling water flowing from the tea pot (Sagittarius). You can see the steam (the Milky Way) rising above it. The myth of scorpius and Orion is perhaps the most famous legend related to celestial mythology and, as we see, its origin goes back at least until the first description of the classic constellations. The form of this constellation really remembers to the one of a scorpion, reason why she is very showy, specially due to the considerable brightness of his main stars, one is the red Antares. So showy it was for the Greeks that eztended it until the neighbor, and weak, constellation of pound, reason why this one would be well-known alternatively in the antiquity like the clamps. In Greek mythology, the story of Scorpius involves Orion, the hunter. Orion boasted that he was the greatest hunter in the universe. When Zeus' wife, Hera, heard what he was saying, she became infuriated and sent a poisonous scorpion to kill him. Orion fought with this creature for days and nights without any success. When weary Orion was not looking, the creature sneaked in and stung him to death. Zeus took pity on Orion and placed him in the heavens where he appears as a giant, with a girdle, sword, lion's skin, and club. Hera placed the scorpion in the heavens at the opposite end of the sky, so even now, Orion tries to avoid the creature by hiding until it is completely under the horizon. On the other hand Scorpius rises in the east when a few stars of Orion still linger above the western horizon. __ Deep sky objects __ There are four Messier objects in Scorpius (some authorities put a fifth in the constellation as well: M62, but usually it is listed in Ophiuchus). //M4 (NGC 6121)// is a rather near globular cluster (6000-10,000 light years) but without a large telescope it will not appear very spectacular. There may be as many as fifty RR Lyrae variables in the cluster. M4 is located just west of Antares, roughly half way to sigma Scorpii. //M6 (NGC 6405)// is the second-best cluster of the constellation (after M7). This is an open cluster which sometimes bears the name "The Butterfly Cluster". Its brightest star is BM Scorpii, a sixth-magnitude yellow giant. The cluster is about 1500-2000 light years away. //M7 (NGC 6475)// has no name, but is clearly the best deep sky object of the constellation. This magnificent open cluster is extremely large (two full-moon diameters) and quite bright, being visible even to the naked eye under the right conditions. M7 is 4º NNE of lambda Scorpii. It's about 800 light years away. //M80 (NGC 6093)// is a rather faint, very compact, globular cluster in the vicinity of Antares, between this star and beta Scorpii, and more narrowly speaking, nearly midpoint between two 8th-magnitude stars (which are the brightest stars of the region). The cluster is quite distant, some 36,000 light years away, and it takes a very large telescope to study it in detail. //NGC 6231// is a naked-eye open cluster one half degree north of zeta Scorpii (which is in fact a member of the group). This cluster is certainly worthy of being a Messier; while noticeable to the naked eye, binoculars resolve its various members. It's about 5500-6000 light years from us.
