Latest Pleiades Stories
GREENBELT, Md., Nov.
Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster -- a controversy that posed a potential challenge to scientists' basic understanding of how stars form and evolve.
Some of NASA's best and brightest will showcase more than 30 of the agency's exciting computational achievements at SC13, the international supercomputing conference, Nov. 17-22, 2013 in Denver.
Astronomers presented research on Wednesday at the American Astronomical Society (AAS) about how the Cat's Paw Nebula is experiencing a "baby boom."
NASA's flagship Pleiades supercomputer just received a boost to help keep pace with the intensive number-crunching requirements of scientists and engineers working on some of the agency's most challenging missions.
This week the second planet from the sun will pass directly in front of the Pleiades star cluster. It's a rare sunset conjunction that's easy to find with the unaided eye, but best seen through binoculars or a small telescope.
Venus's rendezvous with the Pleiades star cluster and the increasing prominence of Mars in the east-southeast part of the sky mark two of the highlights for stargazers to enjoy during the month of April.
NASA's largest supercomputer is seventh on the TOP500 list of the world's most powerful, high-performance computers.
NASA will showcase the latest achievements in climate simulation, space exploration, aeronautics engineering, science research and supercomputing technology at the 23rd annual Supercomputing 2010 (SC10) meeting.
Orion (the hunter) Constellation -- Location: Celestial Equator (visible in both Northern and Southern Hemispheres); Coordinates: Right Ascension: 05h; Declination: -05; Source: Greek mythology, Arab, ancient Indian & Egyptian The pattern in the constellation Orion was recognized as a human figure by many ancient cultures. Orion's position on the Celestial Equator makes it visible all over our planet. Ancient Indians saw the figure as a king who had been shot by an arrow (represented by...
Star Cluster -- Star clusters are physically bound systems of stars. In order of low compactness to high compactness (and in some sense also age) they range from stellar associations to open clusters to globular clusters. Star clusters are held together by the gravitation of their members. Due to both external (encounters with massive objects, influence of the host galaxy) and internal (encounters with other cluster members, stellar evolution) influences, clusters slowly evaporate. Their...
Open Cluster -- An open cluster is a group of star formed from a molecular cloud, the illuminated parts of which we see as one or more nebulae. They are also called galactic clusters since they exist within the galaxy. All the stars in an open cluster have more or less the same age and the same chemical composition, so any difference between them is solely due to their mass. Most open clusters are dominated by their O-type and B-type giant blue stars, which are very luminous but...
Pleiades -- in astronomy, in astronomy, famous open star cluster in the constellation Taurus; cataloged as M45. The cluster consists of some 500 stars, has a diameter of 35 light-years, and is 400 light- years distant from the earth. Six stars are easily visible to the naked eyeAlcyone (the brightest), Electra, Celaeno, Sterope, Maia, and Taygete. Known as the Seven Sisters, this group was named by the Greeks for the seven daughters of Atlas and Pleione; the seventh Pleiad was,...
