The Cosmological Evolution Survey (COSMOS) is an astronomical survey designed to probe the formation and evolution of galaxies as a function of both cosmic time (redshift) and the local galaxy environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra, Herschel, NuStar) and a number of large ground based telescopes (Keck, Subaru, Very Large Array (VLA) , European Southern Observatory Very Large Telescope (ESO-VLT), United Kingdom Infrared Telescope (UKIRT), The National Optical Astronomical Observatory (NOAO) Badde and Blanco telescopes, the Canada France Hawaii Telescope (CFHT), and others) with many ongoing surveys. Over 2 million galaxies are detected, spanning 75% of the age of the Universe. The COSMOS survey involves more than 100 scientists in a dozen countries.
- In 'For the Public' you can learn about the different telescopes that have collected data in the COSMOS field, some of the scientific questions about the Universe that we are trying to answer, have a look at some of the images with the COSMOS SkyWalker and meet our team Artist-in-Residence Karel Nel.
- 'For Astronomers' provides astronomers and students with links to the COSMOS databases, a comprehensive summary of all data available at each wavelength, a list of team members and access to the enhanced data products such as photometric redshift, large scale structure and morphology catalogues, as well as an image cutout tool and the HELP initiative.
- 'For Reviewers' gives an detailed summary of the multiwavelength data available in COSMOS, suitable for an expert audience and reviewers.
- In 'Publications', 'News' and in the Spotlight below you can find out about some of the exciting scientific research that is being conducted by members of the COSMOS collaboration.

COSMOS Co-I Bahram Mobasher has received nearly $4.5 million from NASA to develop research, education, training and collaborative opportunities in big data and visualization at the University of California, Riverside. The five-year research project, called “Fellowships and Internships in Extremely Large Data Sets” (FIELDS), will train underrepresented minority students in science, technology, engineering and mathematics (STEM) fields. FIELDS is a partnership between UC Riverside, NASA’s Jet Propulsion Laboratory (JPL), the California State University system, and the state’s two-year community colleges. Graduate and undergraduate students interested in working on COSMOS through his grant are encouraged to contact Dr. Mobasher. For more information visit: http://ucrtoday.ucr.edu/28942
