scorpion constellation étoiles

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. In a Greek myth without Orion, the celestial scorpion encountered Phaethon while he was driving his father Helios' Sun Chariot. In another version, it was the Earth that sent the scorpion after Orion had boasted that he could kill any wild beast. It contains a number of notable stars and deep sky objects, including the bright stars Antares and Shaula, the Butterfly Cluster (Messier 6), the Ptolemy Cluster (Messier 7), Cat’s Paw Nebula (NGC 6334), the Butterfly Nebula (NGC 6302), and the War and Peace Nebula (NGC 6357).

It is a hot star, with a mass 15 times that of the Sun and a radius more than six times solar. It has a visual magnitude of 2.307. The bright stars in M4 are mostly hot, blue, class B stars, but the brightest one is a class K orange giant, BM Scorpii. C'est une des étoiles de la constellation d'Aquila. The view shows many hot young stars, glowing clouds of gas and weird dust formations sculpted by ultraviolet radiation and stellar winds. CONSTELLATION SIGNE DU ZODIAQUE BÔNEUR Des pierres naturelles (zircons) viennent sublimer une finition plaqué or unique, céleste, d'un aspect mat légèrement brossé. The two brighter components, Gliese 667 A and Gliese 667 B, orbit each other with a period of 42.15 years, and the third component, Gliese 667 C orbits the pair at an angular separation of 30”. Avec 13 étoiles aussi brillantes (mag 3) que les sept de la Grande Ourse, le Scorpion est deux fois plus frappant que la célèbre constellation nordique. Eta Scorpii is a yellow-white subgiant star evolving into a giant. The brighter of the two components is itself a binary star with an orbital period of 610 years and its own brighter component is a spectroscopic binary, with components separated by only 1.42 miliarcseconds and orbiting each other every 6.82 days. Image: ESO. It is one of the most structurally complex nebulae known. 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. U Scorpii is the fastest known nova with a period of about 10 years.[5]. The close pair of stars ω¹ Scorpii and ω² Scorpii are an optical double, which can be resolved by the unaided eye. Scorpius is one of the constellations of the zodiac and is located in the Southern celestial hemisphere.Its name is Latin for scorpion, and its symbol is (Unicode ♏). Gliese 667 A is a main sequence star belonging to the spectral class K3 V, smaller and less massive than the Sun. The cluster is believed to be around 3.2 million years old. Eta Scorpii is a rapid rotator, with a projected rotational velocity of 150 km/s. Kappa Scorpii is a spectroscopic binary star, composed of two stars that cannot be resolved with a telescope. It has a visual magnitude of 5.503. It was discovered by the French astronomer Nicolas Louis de Lacaille in 1751. The sixth component in the Xi Scorpii system is not confirmed to be gravitationally bound to the other stars. C'est une des étoiles de la constellation du Bouvier. It has a companion with an apparent magnitude of 5.36 located 6.470 arc seconds away from the primary star. The whole gas cloud is about 50 light-years across. It has an apparent magnitude of 10.43 and an absolute magnitude of -6.3. U Scorpii is the fastest known nova and one of the 10 known recurring novae in the Milky Way galaxy. Sometimes the star is also known as Iclarcrau or Iclarkrav. It has a 10th magnitude companion at a separation of 37.5 seconds of arc. The constellation is easy to find in the sky because it is located near the centre of the Milky Way. [4] This means that at its brightest it is the second brightest star in Scorpius. Each has at least 10 solar masses and both are expected to end their lives in massive Type II supernova explosions. Cette constellation se distingue par son étoile dominante, Antarès, particulièrement brillante et rougeâtre. In total, the Cat’s Paw Nebula could contain several tens of thousands of stars.The nebula appears red because its blue and green light are scattered and absorbed more efficiently by material between the nebula and Earth. The central star, a white dwarf, has a surface temperature in excess of 200,000 K, which makes it one of the hottest stars in the galaxy. Messier 7 is another open star cluster in Scorpius, located near the scorpion’s stinger. Theta Scorpii is an evolved bright yellow giant star belonging to the spectral class F0 II. Le Scorpion est une constellation facilement observable. Scorpius is one of the zodiac constellations, first catalogued by the Greek astronomer Ptolemy in the 2nd century. Babylonians knew it as GABA GIR.TAB, or “the breast of the scorpion,” in Egypt it represented the scorpion goddess Serket, and in Persia, it was known as Satevis, one of the four “royal stars.”. A planet believed to be a gas giant was discovered orbiting the star in 2007, and another extrasolar planet was discovered in 2012. The star’s estimated age is about 12 million years. It has an apparent magnitude of 3.93 and is approximately 424 light years distant. C'est une étoile super-géante rouge, en fin de vie, dont la taille atteint 700 fois celle du soleil ! M80 was discovered in 1781 by Charles Messier. Cat’s Paw Nebula (Bear Claw Nebula) – NGC 6334 (Gum 64). The star’s traditional name, Sargas, is of Sumerian origin. The star is 73.5 light years distant from the solar system. It was the site of a rare discovery in 1860 when Arthur von Auwers discovered the nova T Scorpii.[6]. Lambda Scorpii is a multiple star system with three visible components, Lambda Scorpii A, Lambda Scorpii B, and Lambda Scorpii C. Lambda Scorpii A is a triple star system composed of two class B stars and a pre-main sequence star. C'est une étoile de la constellation du Scorpion. NGC 6231 is an open cluster in Scorpius. Zeta-1 Scorpii is a hypergiant star belonging to the spectral class B1.5Iae, with an apparent magnitude of 4.705. Delta Scorpii’s traditional name, Dschubba (or Dzuba) comes from the Arabic jabhat, which means “the forehead,” referring to the scorpion’s forehead. The two constellations lie opposite each other in the sky, and Orion is said to be fleeing from the scorpion as it sets just as Scorpius rises. The distance between them is believed to be only around 15 solar radii. The X-ray flux is associated with the star V818 Scorpii, a blue variable which is the optical counterpart to Scorpius X-1. Moreover, the entire constellation of Libra was considered to be claws of Scorpius (Chelae Scorpionis) in Ancient Greek times, with a set of scales held aloft by Astraea (represented by adjacent Virgo) being formed from these western-most stars during later Greek times. Gliese 667 C is a red dwarf belonging to the spectral class M1.5V. Pismis 24-1 consists of at least three objects and has the stellar classification O3.5If/O4III. The primary star in the Lambda Scorpii A system is a Beta Cephei type variable. HD 159868 is a yellow dwarf with the stellar classification G5V. It has an apparent magnitude of 3.56 and is approximately 517 light years distant from the solar system.
