CallUrl('www>astropix>comhtml',0), In late November the Sun crosses over the northern part of Scorpius for about 5 days, after which it passes into the constellation of ~TildeLink() until mid-December. Palomar 6 is approximately 18,900 light years distant from Earth. Asclepius saw a snake slithering toward his body and killed it. It is the fourth closest known individual star to the Sun. The cloud consists of a high concentration of molecular gas and dust, and it absorbs the visible light of the stars in the background. By comparison, a massive star with a stunning bow shock, called Zeta Ophiuchi (or Zeta Oph), is traveling around the galaxy faster than the sun, at 54,000 mph (24 kilometers per second) relative to … High S/N, high-resolution observations of the interstellar Li absorption lines toward the stars Zeta Ophiuchi and Zeta Persei are reported. The German mathematician and astronomer Johannes Kepler started observing the event in Prague on October 17 and tracked it for an entire year. CallUrl('astronomyonline>orgasp',0), ~TildeLink() is a sprawling constellation and its many stars can sometimes be hard to identify.

Palomar 6 is a globular cluster discovered by Robert G. Harrington and Fritz Zwicky. These baby stars are just now forming; many of them are still enveloped in their own tiny compact nebulae. NGC 6633 is another open cluster in Ophiuchus, discovered by Philippe Loys de Chéseaux in 1745-1746. The primary component in the system is a spectroscopic binary with the stellar classification of B2 IV, matching the spectrum of a blue-white subgiant star. And, at the bottom left of the image, there are two lines emerging from the edge. The cluster was discovered by Charles Messier in 1764. It was re-activated in 2013. opposition 1. An exoplanet is a planet that orbits a star beyond our sun. Alnitak, Zeta Orionis, ζ Ori, 50 Orionis, 126 G.

The star’s traditional name, Sinistra, means “the left side” in Latin. The star is classified as a Beta Cephei variable, a star that exhibits variations in brightness as a result of pulsation of its surface. Sabik, Eta Ophiuchi, is the second brightest star in the constellation. This theory, however, has not been confirmed by sufficient evidence. "Miri" (1966), episode of Star Trek: The Original Series written by Adrian Spies. He holds the head of the snake in his left hand and its tail in his right hand. It forms an optical double with the star Epsilon Ophiuchi, or Yed Posterior. Gum 72. Image: NASA, Bruce Balick University of Washingtom, Vincent Icke Leiden. Page 1 of 2 - Becvars 14 star names - posted in Astro Art, Books, Websites & Other Media: I just did a post on my blog about the 14 star names that Antonin Becvar introduced with the Skalnate Pleso atlas in 1948. It is 2.56 degrees south of the ecliptic, so it can be occulted by the Moon, and (rarely) by planets. It is approximately 25,800 light years distant from Earth. The only known stars that are closer to us are the three components of the Alpha Centauri system in Centaurus constellation. What is what? The planetary nebula M2-9, also known as the Twin Jet nebula, Minkowski’s Butterfly, or the Butterfly Nebula, is another planetary nebula in Ophiuchus. Parameter (semilatus rectum) p =a(1−e2). Its estimated rotational velocity may be 400 km/s. Zeta Ophiuchi (ζ Oph, ζ Ophiuchi) is a star located in the constellation of Ophiuchus. At magnitude 4 it appears as a dim star visible to the unaided eye away from city lights. Ophiuchus contains seven Messier objects: Messier 9 (M9, NGC 6333), Messier 10 (M10, NGC 6254), Messier 12 (M12, NGC 6218), Messier 14 (M14, NGC 6402), Messier 19 (M19, NGC 6273), Messier 62 (M62, NGC 6266) and Messier 107 (M107, NGC 6171). The three stars have apparent magnitudes of 5.29, 5.33 and 6.34. The constellation got a notable mention in John Milton’s Book 2 of Paradise Lost, in which Satan was compared to a comet “that fries the length of Ophiuchus huge/In th’ arctic sky.”. The signs of the Zodiac are Capricornus, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius. ~TildeLink() is, of course, not one of the traditional 12 constellations of the Zodiac. At the 3 o’clock position, relative to the bright central region, and about two-thirds of the way from the centre to the edge, there is a small faint red dot. (integer) HD No. The cluster’s core is quite bright and spans about 35 light years across, and the cluster’s spatial diameter spans about 83 light years. It is in the constellation Ophiuchus. Around the year 9,800, the star will make its closest approach to the Sun and come within 3.75 light years. It lies 4.5 degrees to the west-southwest of the star Theta Ophiuchi and can be seen with binoculars. Major Stars . Gamma Ophiuchi has a mass 2.9 times that of the Sun, a radius 1.8 times solar, and is 29 times more luminous than the Sun. IC 4603-04 is a reflection nebula in Ophiuchus. It is located only 6,500 light years from the Galactic Centre. Both are blue main sequence dwarf stars that are loosely bound to one another, despite being separated by a hefty one light year distance. The traditional name Sinistra is a Latin word which means left side.
