a thousand times as sensitive as previous infrared surveys. The initial survey, consisting of each sky position imaged at least eight times, was completed by July 2010. UKIRT Infrared Deep Sky Survey (UKIDSS) – a collection of ground based northern hemisphere surveys (GPS, GCS, LAS, DXS, UDS) using the WFCAM camera on UKIRT, some wide and some very deep, in Z, Y, J, H, & K bands 2005– VISTA public surveys – a collection of ground based southern hemisphere surveys (VVV, VMC, VHS, VIKING, VIDEO, UltraVISTA), of various areas and depths, in Z, Y, J, H, & Ks bands, 2009–present SCUBA-2 All Sky Survey Radio Third Cambridge Catalogue of Radio Sources ("3C") - Survey at 159 and 178 MHz published in 1959 HIPASS – Radio survey, the first blind HI survey to cover the entire southern sky. 1997–2002 Ohio Sky Survey – Over 19,000 radio sources at 1415 MHz. 1965–1973. NVSS – Survey at 1.4 GHz mapping the sky north of −40 deg FIRST – Survey to look for faint radio sources at twenty cms. SUMSS - Survey at 843 MHz, mapping the sky south of -30 deg with similar sensitivity and resolution to the northern NVSS PALFA Survey – On-going 1.4 GHz survey for radio pulsars using the Arecibo Observatory. GALEX Arecibo SDSS Survey GASS designed to measure the neutral hydrogen content of a representative sample of ~1000 massive, galaxies C-BASS – On-going 5 GHz all sky survey to aid in the subtraction of galactic foregrounds from maps of the Cosmic Microwave Background EMU – A large radio continuum survey covering 3/4 of the sky, expected to discover about 70 million galaxies GMRT - The Giant Metrewave Radio Telescope's TGSS ADR mapped the sky at 150 MHz. HTRU – A pulsar and radio transients survey of the northern and southern sky using the Parkes Radio Telescope and the Effelsberg telescope. Gamma-ray Fermi Gamma-ray Space Telescope, formerly referred to as the "Gamma-ray Large Area Space Telescope (GLAST)." 2008–present; the goal for the telescope's lifetime is 10 years. Multi-wavelength surveys GAMA – the Galaxy And Mass Assembly survey combines data from a number of ground- and space-based observatories together with a large redshift survey, performed at the Anglo-Australian Telescope. The resulting dataset aims to be a comprehensive resource for studying the physics of the galaxy population and underlying mass structures in the recent universe.
