Latest Sloan Digital Sky Survey Stories
Astrophysicists find 2 Earth-sized bodies with oxygen rich atmospheres - only snag is they're stars not planets.
BOSS, the Baryon Oscillation Spectroscopic Survey, is the most ambitious attempt yet to map the expansion history of the Universe using the technique known as baryon acoustic oscillation (BAO).
The Catalina Sky Survey detects potentially hazardous asteroids and comets. Now a spin-off survey is finding a windfall of "optical transients" in the same data.
Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, â€œsupernovaeâ€ for short, certainly works: itâ€™s how dark energy was discovered in the first place.
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II).
The Apache Point Observatory Galactic Evolution Experiment, or APOGEE, is one of four experiments of the new Sloan Digital Sky Survey III, using the astronomical facilities at Apache Point Observatory in New Mexico.
A Unique Way to Measure Dark Energy With Galaxies and Quasars
A team led by a Yale University astronomer has discovered the least luminous, most dark matter-filled galaxy known to exist.
Microsoft Corp. (MSFT) (MSFT) launched its WorldWide Telescope late Monday, bringing the free Web-based program for zooming around the universe to a broad audience.
A University of Florida-led sky survey that may double the number of known planets outside the solar system is part of a major new survey program announced today at the American Astronomical Societyâ€™s annual meeting in Austin, Texas.
