CoRoT (French: ; English: Convection, Rotation and planetary Transits) was a space telescope mission which operated from 2006 to 2013. The mission's two objectives were to search for extrasolar planets with short orbital periods, particularly those of large terrestrial size, and to perform asteroseismology by measuring solar-like oscillations in stars. The mission was led by the French Space Agency (CNES) in conjunction with the European Space Agency (ESA) and other international partners.

thumb|For four years beginning in May 2010, the Pan-STARRS observatory surveyed the entire three-quarters of the sky visible from Hawaii many times in many colors of light. One of the survey's goals was to look for moving objects and transient or variable objects, including asteroids that could potentially threaten the Earth.

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guo Shoujing Telescope (Chinese: 郭守敬望远镜) after the 13th-century Chinese astronomer, is a meridian reflecting Schmidt telescope, located in Xinglong Station, Hebei Province, China. Undertaken by the Chinese Academy of Sciences, the telescope is planned to conduct a 5-year spectroscopic survey of 10 million Milky Way stars, as well as millions of galaxies. The project's budget is RMB 235 million yuan.

SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) is a project consisting of SPECULOOS Southern Observatory (SSO) at the Paranal Observatory in Chile and SPECULOOS Northern Observatory (SNO) at the Teide Observatory in Tenerife.

The finderscope usually has a much smaller magnification than the main telescope, thus providing a larger field of view

The Korea Microlensing Telescope Network (KMTNet; ) is an ongoing wide-field photometric system that aims to discover extrasolar planets using gravitational microlensing. The system leverages three identical 1.6 m wide-field optical telescopes located at the Cerro-Tololo Inter-American Observatory (CTIO) in Chile, the South African Astronomical Observatory (SAAO) in South Africa, and the Siding Spring Observatory (SSO) in Australia. All three telescopes share a latitude of −30 degrees enabling continuous monitoring of the galactic bulge during 8 months of each year and other targets in the sou
