Three of the light-gobbling monsters nuzzle shoulder to shoulder in SDSS J084905.51+111447.2, a system of three merging galaxies about 1 billion light-years from Earth, a new study reports.

The team found the new galaxies by processing imaging data from the Sloan Digital Sky Survey (SDSS-II), which covers about one-fifth of the sky around the North Galactic Pole. The astronomers ...

We have carried out a systematic survey of quasars at z > 5 using photometry from the Sloan Digital Sky Survey (SDSS) 17, the two Micron All Sky Survey (2MASS) 18 and the Wide-field Infrared ...
