The Boötes Dwarf Galaxy ( Boo I dSph) is a galaxy discovered in 2006, which appears faint, with a luminosity of 100,000 L☉ and an absolute magnitude of -5.8. It lies about 197,000 light-years (60.4 kiloparsecs) away in the constellation Boötes. Boötes ( / boʊˈoʊtiːz / boh-OH-teez) is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere. The name comes from Latin: Boōtēs, which comes from Greek: Βοώτης, translit. Boṓtēs ' herdsman ' or ' plowman ' (literally, ' ox -driver'; from βοῦς boûs ' cow ').

Boötes is one of the largest constellations in the sky. Located in the northern celestial hemisphere, the constellation is dominated by the Kite, a diamond-shaped asterism formed by its brightest stars. The constellation's name comes from the Greek word Βοώτης, Boōtēs, which means ox driver, plowman, or herdsman. Boötes is the 13th largest constellation in the night sky and contains one of the brightest stars in the sky, Arcturus. Boötes is an ancient Greek word that roughly translates as the ox-driver, or. The Boötes Dwarf Galaxy, also known as Boötes I, is a satellite galaxy to the Milky Way. It lies approximately 197,000 light years from Earth. It is located in the constellation Boötes, the Herdsman. Boötes I is a rather faint galaxy. It has an apparent visual magnitude of 13.1 and an absolute magnitude of -5.8. The Boötes Void ( / boʊˈoʊtiːz / boh-OH-teez) (colloquially referred to as the Great Nothing) [1] is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name.

Below is a list of the major clusters of galaxies in the two Bootes Superclusters. The exact distance to one of these clusters (A1861) is currently uncertain and it could be a background cluster. Bootes contains the third brightest star in the night sky - Arcturus (aka. alpha Boötis) - whose Greek name "Arktos" also means "bear", and is associated with all things northern (including the. - Boötes I (Boötes Dwarf Galaxy) is a diminutive galaxy just 720 light years across that is located about 197,000 light years from Earth. With an apparent magnitude of 13.1, it is one of the faintest known galaxies, and its distorted shape is believed to be the result of the Milky Way's tidal gravity pulling it apart. Boötes III is an overdensity in the Milky Way 's halo, which may be a disrupted dwarf spheroidal galaxy. It is situated in the constellation Boötes and was discovered in 2009 in the data obtained by Sloan Digital Sky Survey. [2]

Bootes is home to three fascinating deep sky objects including a Supervoid, a Dwarf Galaxy and a Globular Cluster. Check them out; Bootes void: this Supervoid or the Great Void is spherical in shape and is now known to contain around 60 galaxies. It is also 250 light-years in diameter. Boötes II or Boo II is a dwarf spheroidal galaxy situated in the constellation Boötes and discovered in 2007 in the data obtained by Sloan Digital Sky Survey. [4] The galaxy is located at the distance of about 42 kpc from the Sun and moves towards the Sun with the speed of 120 km/s.

Boötes is generally referred to as the Bear Watcher since it appears to be watching over the constellations Ursa Major and Ursa Minor. Location: Northern Spring 15h RA 30° Dec. The name Arcturus, the alpha star of Boötes, means bear driver. It is a zero-magnitude red giant and is the third brightest star as seen from.

Boötes Void One Of The Largest Voids In The Universe Watch on The American astronomer, Robert Kirshner, and his team discovered it back in 1981. When we first observed the void, we found only one galaxy inside. Since then, we've detected only a few dozen more. The average distance from each galaxy would place one every 10 million light-years. A Fatal Attraction Using the stars they identified, the authors modeled the structure of the stream and also analyzed its chemical composition, in part to determine whether the stream was created by a disrupted dwarf galaxy or large globular cluster.
