Measured colors (essentially the ratio of how bright objects appear in different wavelength filters) for objects detected in the United Kingdom Infrared Telescope Infrared
Deep Sky Survey that passed researchers» initial selection criteria (shown by the dashed lines).
The same
deep sky survey, conducted with the Subaru telescope in Hawaii and the Dark Energy Survey Camera in Chile, has also turned up about a dozen other objects around 80 to 90 AU from the sun.
The initial discovery of this quasar (given the identity J1342 +0928) came to light thanks to the mining of three large area surveys: the DECam Legacy Survey (DECaLS) that is being carried out with the Dark Energy Camera on the National Science Foundations Blanco 4 - m telescope at the Cerro Tololo Inter-American Observatory in Chile, NASAs Wide - field Infrared Survey Explorer (ALLWISE), and the United Kingdom Infrared Telescope
Deep Sky Survey (UKIDSS) Large Area Survey.

This
survey, called the «Hubble Ultra
Deep Field,» (in 1995 and 1998) was targeted on a region of the
sky that was nearly devoid of known objects, so as to be (hopefully) representative of conditions in the distant Universe.
The universe suddenly looks a lot more crowded, thanks to a
deep -
sky census assembled from
surveys taken by NASA's Hubble Space Telescope and other observatories.
Captured using the exceptional
sky -
surveying abilities of the VLT
Survey Telescope (VST) at ESO's Paranal Observatory in Chile, this
deep view reveals the secrets of the luminous members of the Fornax Cluster, one of the richest and closest galaxy clusters to the Milky Way.
The ability to sift through large amounts of data and perform complex analyses very quickly and in a fully automated fashion could transform astrophysics in a way that is much needed for future
sky surveys that will look
deeper into the universe — and produce more data — than ever before.
The KiDS analysis of data from the VST is an important step but future telescopes are expected to take even wider and
deeper surveys of the
sky.
Deep - field
surveys are intended to look at faint galaxies; they point at small areas of the
sky for a longer period of time, meaning the total volume of space being sampled is relatively small.
Sheppard and Trujillo, along with David Tholen of the University of Hawaii, are conducting the largest,
deepest survey for objects beyond Neptune and the Kuiper Belt and have covered nearly 10 percent of the
sky to date using some of the largest and most advanced telescopes and cameras in the world, such as the Dark Energy Camera on the NOAO 4 - meter Blanco telescope in Chile and the Japanese Hyper Suprime Camera on the 8 - meter Subaru telescope in Hawaii.
Instead of conducting a narrow and
deep study of a small area of the
sky, the team broadened their scope to produce the widest
survey of very distant galaxies ever attempted.
A research team has recently added one more member to the list, by announcing the detection of an exoplanet at a distance of approximately 13,000 light - years away, which was spotted by NASA's Spitzer space telescope in conjunction with a ground - based,
deep -
sky survey.
Despite these observational challenges, astronomers have successfully spotted many thousands of such microlensing events as part of various comprehensive
deep -
sky surveys during the last couple decades which have monitored hundreds of millions of stars for many years at a time, like the MACHO Collaboration project, the Microlensing Observations in Astrophysics, or MOA, and the Optical Gravitational Lensing Experiment, or OGLE.
The pointed observations will be used for
deep surveys of selected
sky areas and systematic observations of important astronomical targets.
