About NGTS

The Next-Generation Transit Survey (NGTS) is a wide-field photometric survey designed to discover transiting exoplanets of Neptune-size and smaller around bright stars (magnitude V<13).

NGTS employs an array of fully-robotic small telescopes operating in the 600-900nm band, thereby maximizing sensitivity to bright but relatively small host stars (K and early-M spectral type).

Detailed simulations demonstrate a target sample more than five times larger than Kepler in this magnitude range. NGTS will therefore find the brightest exoplanets of Neptune and super-Earth size, providing the prime targets for characterization by VLT, ELT and JWST. Bright targets provide the key to understanding planetary structure and evolution, as well as atmospheric composition.

NGTS will be sited at ESO-Paranal, which meets strict requirements for low water vapor and excellent photometric conditions. This also strengthens the synergy with ESO telescopes. Our science requirement of 0.1% photometric precision across a wide field is technically demanding, and so we have demonstrated all key technologies using a prototype system, which operated on La Palma during 2009 and 2010.

NGTS also benefits from hardware and software heritage from the WASP project, which is currently world leading in the discovery of transiting exoplanets of Jupiter size.
