About this deal

The stars Merak (β Ursae Majoris) and Dubhe (α Ursae Majoris) are known as the "pointer stars" because they are helpful for finding Polaris, also known as the North Star or Pole Star. By visually tracing a line from Merak through Dubhe (1 unit) and continuing for 5 units, one's eye will land on Polaris, accurately indicating true north.

Ursa Major constellation belongs to the Ursa Major family of constellations. This family of constellations consists of Boötes, Camelopardalis, Canes Venatici, Coma Berenices, Corona Borealis, Draco, Leo Minor, Lynx, and Ursa Minor. In some Native American tales, the bowl of the Big Dipper represents a large bear and the stars that mark the handle are the warriors chasing it. Since the constellation is pretty low in the sky in autumn, the legend says that it is the blood of the wounded bear that causes the leaves to turn red. Alioth belongs to the spectral class A0pCr. The p stands for peculiar because the star’s spectrum of light is similar to that of an Alpha-2 Canum Venaticorum variable. Alioth exhibits fluctuations in its spectral lines with a period of 5.1 days. Dubhe – α Ursae Majoris (Alpha Ursae Majoris) The second star from the end of the tail or handle is Mizar-Alcor or known as Zeta Ursae Majoris. It is the constellation’s fourth-brightest star. Mizar forms a famous double star, with its companion Alcor. The Arabs termed these two stars as the horse and rider. Among them, the ability to see these two stars with the naked eye was often considered a test of good eyesight. Ursa Major is located in the second quadrant of the northern hemisphere. It can be seen at latitudes between +90° and -30°. The best time to see this constellation is in the spring. At this time Ursa Major is high above the north-eastern horizon.

Except for Dubhe and Alkaid, the stars of the Big Dipper all have proper motions heading toward a common point in Sagittarius. A few other such stars have been identified, and together they are called the Ursa Major Moving Group. Alioth is the brightest star in Ursa Major and the 31st brightest star in the night sky. It has an apparent magnitude of 1.76 and is approximately 81 light years distant. The star’s traditional name comes from the Arabic word alyat, which means “fat tail of a sheep.” Alioth is the star in the bear’s tail that is closest to the body of the bear. Alkaid is notable for being one of the hottest stars that can be seen without binoculars. It has a surface temperature of 20,000 kelvins. The star has six solar masses and is about 700 times more luminous than the Sun. Like Dubhe, Alkaid does not belong to the Ursa Major Moving Group. Supergiants are the largest and brightest stars, often many hundred times larger (and much brighter) than our Sun. By far the most important and famous star in Ursa Minor is the North Star or Pole Star, known as Polaris. This is the star at the very end of the bear’s long tail.

Lambda Ursae Majoris is a star belonging to the spectral class A2 IV, which means that it is evolving into a giant as its hydrogen supply becomes exhausted. The star has an apparent magnitude of 3.45 and is approximately 138 light years distant. M101, also called the Pinwheel Galaxy, is a face-on spiral galaxy located 25 million light-years from Earth. It was discovered by Pierre Méchain in 1781. Its spiral arms have regions with extensive star formation and have strong ultraviolet emissions. [19] It has an integrated magnitude of 7.5, making it visible in both binoculars and telescopes, but not to the naked eye. [22]Look for seven major stars:four in the “bowl” and three in the “handle.”The two stars on the outside of the bowl are called the “pointer” stars. They point to Polaris, a bright star that is also called the North Star because with it you can figure out which way isnorth. To findnorth: In episode 3, the executive chef and co-owner of Elske, a creative Chicago spot focused on American cuisine with Danish influences, shares some real talk with Sydney about bad business partners being the downfall of his and his wife, executive pastry chef Anna Posey’s previous restaurant. Mitra Jouhari There are two meteor showers associated with the constellation; the Alpha Ursa Majorids and the Leonids-Ursids. The third star is Alioth, or also referred to as Epsilon Ursae Majoris. Alioth is the brightest star in the Ursa Major constellation. It is the 33rd brightest star in the sky, consisting of magnitude 1.76. It has a distance of around 80 light-years from Earth.

Move your eyes left (south) until you come to a very bright star—that’s Sirius, the nose of thedog. Similarly, the imaginary line that stretches along the handle of the Dipper leads to the bright star Arcturus, the bear keeper, located in the constellation Boötes, the Herdsman. If you follow the line further, you will find Spica, the brightest star in the constellation Virgo and also one of the brightest stars in the sky. The October Ursae Majorids were discovered in 2006 by Japanese researchers. They may be caused may be a long period comet. [26] The shower peaks between October12 and 19. [27]In episode 3, Sydney makes a new hire to the new restaurant’s kitchen crew, who happens to be the former Saturday Night Live cast member, who left the series in 2022 after six seasons. It doesn’t hurt that he is also a Chicago native. Rob Levitt Each of the two main components in the Xi Ursae Majoris system is itself a spectroscopic double, and has a low mass companion. Xi Ursae Majoris is also notable for being the first binary star to have its orbit calculated, in 1828. The Ursa Major constellation also contains 13 stars within it that are confirmed as planets. There are two meteor showers associated with the constellation; the Alpha Ursa Majorids and the Leonids-Ursids.

Ursa Major contains seven Messier objects that are located within and around the constellation. The most famous of these seven are the Pinwheel Galaxy, Bode’s Galaxy, the Cigar Galaxy, and the Owl Nebula. James B. Kaler (28 July 2011).

The ancient Chinese believed the seven bright stars represented Tseih Sing, the Government, or Pih Tow, the Northern Measure. In South Korea, the constellation is referred to as the Seven Stars of the North. Ursae Majoris, known by the Arabic name Dubhe ("the bear"), which at a magnitude of 1.79 is the 35th-brightest star in the sky and the second-brightest of Ursa Major.

The Iroquois interpreted Alioth, Mizar, and Alkaid as three hunters pursuing the Great Bear. According to one version of their myth, the first hunter (Alioth) is carrying a bow and arrow to strike down the bear. The second hunter (Mizar) carries a large pot – the star Alcor – on his shoulder in which to cook the bear while the third hunter (Alkaid) hauls a pile of firewood to light a fire beneath the pot.

The most solidly 'reconstructed' Indo-European constellation is Ursa Major, which is designated as 'The Bear' (Chapter 9) in Greek and Sanskrit (Latin may be a borrowing here), although even the latter identification has been challenged. Ursa Major belongs to the Ursa Major family of constellations, along with Boötes, Camelopardalis, Canes Venatici, Coma Berenices, Corona Borealis, Draco, Leo Minor, Lynx, and Ursa Minor.
