Late Old English, from Latin taurus "bull, bullock, steer," also the name of the constellation, from PIE *tau-ro-"bull" (source also of Greek tauros, Old Church Slavonic turu "bull, steer;" Lithuanian tauras "aurochs;" Old Prussian tauris "bison"); from PIE *tauro-"bull," from root *(s) taeu- "to bear." The word is used in many languages for various animals resembling a bull. It is also the name of a star cluster in the constellation Taurus.
Taurus is named after the constellations Taurus, who has the same etymology as Europe. Also called "the Bull," it contains the brightest star in the sky, Aldebaran, which means "the leader" or "the king."
Aldebaran is an alpha Draconi star that lies about 26 light-years from Earth in the constellation Taurus. It has a mass about 7% that of our Sun and it burns with a luminosity 10^30 watts (10 billion trillion watts). Its outer atmosphere has been detected by radio telescopes, indicating that it may have a planet or planets like our Solar System. Aldebaran's appearance changes periodically due to fluctuations in its internal structure caused by temperature variations.
The Pleiades is a cluster of stars within the constellation Taurus. It has been estimated to contain around 100 stars with masses between 0.5 and 8 times that of the Sun.
"The bull" is one of the most conspicuous and earliest known constellations, with mentions of Taurus dating back to the early Bronze Age. Taurus is well known for its red giant star, Aldebaran, as well as the Pleiades star cluster. It lies between the constellations Cygnus and Scorpius in the northern hemisphere.
Taurus is a rich constellation that contains several stars of relatively low luminosity, so it makes an excellent contrast against the bright stars of the sky. The name "Taurus" comes from the Greek word for "bull," which reflects the shape of the constellation as seen from Earth. However, the designation "the Bull" is more accurate since there are actually three distinct shapes depicted by Taurus: a young bull, a mature bull, and a hunter's trophy case. All together, Taurus covers an area of sky about half the size of a full moon.
Taurus is one of the constellations that is visible to the naked eye. It forms a large part of the zodiac constellation system, which includes the other twelve constellations that make up the year. Taurus is centered on Aldebaran, which has an apparent magnitude of 1.54. It takes about four hours to traverse all parts of Taurus with a starting point near Alpha Centauri (3.8 light years away).
Taurus the Bull is a zodiac constellation seen in the evening sky throughout the Northern Hemisphere winter and spring (or the Southern Hemisphere summer and fall). From roughly May 14 to June 21, the sun travels through the constellation Taurus, although you can't see Taurus when the sun is within its boundaries. After sunset on these days, look up to see Taurus above the western horizon.
Taurus is one of the constellations that are visible from Earth. It's part of the larger family of constellations called "the Milky Way" because of the many stars that can be seen with the naked eye from Earth. The constellation is located between 30 degrees north and 30 degrees south latitude on the celestial equator and spans about 160 degrees in length. It has been around since at least 300 B.C. and probably existed long before that. Taurus is named after the Greek god of agriculture and livestock breeding.
The bright star Aldebaran is the center of the Taurus constellation. It lies about halfway across the galaxy from the center of our own Milky Way Galaxy. Astronomers use it as a reference point to measure distances to other galaxies. It has been estimated that one light-year is equal to 5.878 x 10^8 miles - or 1.6 x 10^12 kilometers- which is the distance that light travels in a year.
According to Greek mythology, the constellation Taurus recalls Zeus' transformation into a magnificent white bull in order to win the love of the Phoenician princess Europa. After Europa got atop the bull's back, the bull swam across the Mediterranean Sea, carrying Europa all the way to the Greek island of Crete. There she was met by Zeus, who had followed them aboard the boat of his father, Titanos.
Zeus made good on his promise to marry her and took Taurus as his symbol thereafter. The association of Taurus with marriage and fertility makes it a popular choice for new parents.
Taurus is one of the constellations that make up the zodiac. It is composed of two signs: Taurus (the bull) and Auriga (the charioteer). Taurus is known for its strong constitution and patient nature. These characteristics are reflected in the traditional image of the constellation--a massive bull lying down. Underneath the bull lies the beautiful woman representing fertility. She has just awakened him from a deep sleep so he will produce more milk for her infant son. Around her neck is tied a golden apple, symbolizing immortality. This illustrates how important sleep is to Taurus--even a bull like this one needs his rest!
The stars of Taurus include Beta Tauri, which marks the position of the constellation, and Eta Tauri, which is located near the center of the map.
Latin astrum, Ancient Greek astron (astron), aster (aster), Proto-Indo-European *h2ster ("star"), from the root *h2eHs- ("to burn," "to glow"). First used by the Roman author Varro in his book on agriculture.
A term used by astronomers to describe an object that appears in the night sky as a bright point of light, usually referred to as a star. The word is derived from the Greek αστρον for "stars." Astronomers use telescopes to see objects that are too small or distant to be seen with the unaided eye. The study of stars and their properties represents one of the most important areas of research in astronomy.
Stars are classified according to their spectral type. This classification depends upon the color of the starlight and its intensity at different wavelengths. Stars can also be classified by their evolutionary state. A main sequence star is young and hot, while a red giant or a white dwarf is old and cold. A supernova explosion marks the death of a massive star and may produce a gamma ray burst or an electron neutrino signal.
Stars are generated by nuclear fusion reactions that take place inside their cores. Energy is released during this process that allows the star to remain compact while being supported by its own gravity.
