Boötes

(bō-ō`tēz) [Gr.,=the herdsman], northern constellationconstellation,
in common usage, group of stars that appear to form a configuration in the sky; properly speaking, a constellation is a definite region of the sky in which the configuration of stars is contained.

. The figure traditionally associated with Boötes shows a man holding a staff in one hand and two leashed dogs in the other (the Hunting Dogs of the constellation Canes Venatici). Boötes is also known as the Keeper of the Bear because it follows Ursa Major, the Large Bear. It reaches its highest point in the evening sky in June.

Boötes

(boh-oh -teez) (Herdsman) A large constellation in the northern hemisphere near Ursa Major. The brightest stars are Arcturus and the 2nd-magnitude yellow-blue visual binary Epsilon (Ɛ) Boötis, one of several double stars. The area also contains one of the most distant radio galaxies, 3C–295. A giant planet 1.4 times as massive as Jupiter is thought to orbit the 4th-magnitude yellow subgiant Tau (τ) Boötis (spectral type: F6 IV; distance: 16 pc). Abbrev.: Boo; genitive form: Boötis; approx. position: RA 14.5h, dec +30°; area: 907 sq deg.

Boötes

 

a meteor shower with a radiant in the constellation of Boötes. It is associated with Pons-Winnecke’s comet. It was first observed in May and June 1916. It was active in 1916, 1921, and 1927. After 1927 the shower lost its meteors.

(the ox herdsman), a constellation in the northern hemisphere. Its brightest star is Arcturus with a visual stellar magnitude of 0.1. The most favorable conditions for viewing BoÖtes are in April and May. It is visible everywhere in the USSR.

By studying spectra of the star, Cameron and his collaborators teased out the portion of the light that may represent a reflection from the orbiting planet--less than a ten-thousandth of the total light from Tau Bootes. As the planet whips around the star, the movement toward and away from Earth shifts the planet's reflected light to slightly longer and shorter wavelengths.

One of the surprises of the last decade was the discovery of an enormous void -- a hole in the sky -- in the direction of the constellation Bootes. Although that region of the sky appears well populated with bright galaxies, careful distance measurements show that virtually all those bright objects are in either the foreground or the background, leaving a vast, apparently unoccupied region at intermediate distances (approximately 500 million light-years from Earth).
CLIMBING UP the eastern sky at this time of year is little Corona Borealis, east of Bootes. Aside from its distinctive naked-eye shape, it holds two claims to fame: a bright star that unpredictably turns faint, and a faint one that on rare occasions turns bright.
In fact, the celestial wrangler is the constellation Bootes, the Herdsman.
