Led by Berkeley Lab scientists, the Sloan Digital Sky Survey´s BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). In this release BOSS, the largest of SDSS-III's four surveys, provides spectra for 535,995 newly observed galaxies, 102,100 quasars, and 116,474...

Astronomers have released the largest digital, color image of the universe ever recorded--a mosaic created from millions of 2.8 megapixel images recorded over the past decade. The image, which was unveiled during the 217th annual meeting of the American Astronomical Society (AAS) in Seattle, Washington on Tuesday, was captured and assembled by researchers with the Sloan Digital Sky Survey (SDSS). SDSS-III, as it has been dubbed, is a full color representation of the night sky that has a...

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). A part of the Sloan Digital Sky Survey III (SDSS-III), BOSS achieved "first light" on the night of September 14-15, when it acquired data with an upgraded spectrographic system across the entire focal plane of the Sloan Foundation 2.5-meter telescope at Apache Point Observatory in New Mexico. BOSS is...

Two enormous black holes appear to be orbiting one another at the center of a faraway galaxy, formed by the collision of two separate galaxies, astronomers from the National Optical Astronomy Observatory (NOAO) in Tucson reported Wednesday. The two supermassive black holes are locked in orbit about 5 billion light years away from Earth, the scientists said.  One light year is the distance light travels in a year, approximately 6 trillion miles. Data from Apache Point Observatory in New...

"It's the ultimate exercise in archeology," said Steven Majewski, a University of Virginia professor of astronomy and lead scientist on a new project to survey more than 100,000 Milky Way red giant stars -- bright, bloated stars in a late stage of their evolution. The project, 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....

GAINESVILLE, Fla. "” 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 Society's annual meeting in Austin, Texas.The Sloan Digital Sky Survey III, slated to begin mid-year and end in mid-2014, consists of four independent surveys operated by the survey's consortium. One will probe the distant universe and seek to learn more about mysterious dark...

NRAO -- Astronomers have found a relatively tiny galaxy whose black-hole-powered "central engine" is pouring out energy at a rate equal to that of much larger galaxies, and they're wondering how it manages to do so. The astronomers used the National Science Foundation's Very Large Array (VLA) radio telescope and optical telescopes at the Apache Point Observatory to study a galaxy dubbed J170902+641728, more than a billion light-years from Earth. "This thing looks like a quasar in VLA images,...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
