The '''Next-Generation Transit Survey''' ('''NGTS''') is a ground-based robotic search for [[Astronomy:Exoplanet|exoplanet]]s.<ref name="Wheatley-2017" /> The facility is located at Paranal Observatory in the Atacama desert in northern Chile, about 2&nbsp;km from [[Organization:European Southern Observatory|ESO]]'s [[Astronomy:Very Large Telescope|Very Large Telescope]] and 0.5&nbsp;km from the [[Astronomy:VISTA (telescope)|VISTA Survey Telescope]]. Science operations began in early 2015.<ref name="NGTS first light" /> The [[Astronomy:Astronomical survey|astronomical survey]] is managed by a consortium of seven European universities and other academic institutions from Chile, Germany, Switzerland, and the United Kingdom.<ref name="ngts" /> Prototypes of the array were tested in 2009 and 2010 on La Palma, and from 2012 to 2014 at Geneva Observatory.<ref name="ngts" />
 
The aim of NGTS is to discover [[Astronomy:Super-Earth|super-Earth]]s and exo-[[Astronomy:Neptune|Neptune]]s transiting relatively bright and nearby stars with an apparent [[Astronomy:Magnitude|magnitude]] of up to 13. The survey uses transit photometry, which precisely measures the dimming of a star to detect the presence of a planet when it crosses in front of it. NGTS consists of an array of twelve commercial 0.2-metre telescopes ([[F-number|f/2.8]]), each equipped with a red-sensitive [[Engineering:Charge-coupled device|CCD]] camera operating in the visible and near-infrared at 600–900&nbsp;nm. The array covers an instantaneous field of view of 96 square degrees (8&nbsp;deg<sup>2</sup> per telescope) or around 0.23% of the entire sky.<ref name="Wheatley-2013" /> NGTS builds heavily on experience with SuperWASP, using more sensitive detectors, refined software, and larger optics, though having a much smaller field of view.<ref name="Queens-Uni" /> Compared to the [[Engineering:Kepler (spacecraft)|''Kepler'' spacecraft]] with its original Kepler field of 115 square degrees, the sky area covered by NGTS will be sixteen times larger, because the survey intends to scan four different fields every year over a period of four years. As a result, the sky coverage will be comparable to that of [[Astronomy:Kepler space telescope#Second Light (K2)|Kepler's K2 phase]].<ref name="Wheatley-2013" />

NGTS is suited to ground-based [[Astronomy:Photometry|photometric]] follow-up of exoplanet candidates from space-based telescopes such as TESS, [[Engineering:Gaia (spacecraft)|''Gaia'']] and [[Engineering:PLATO (spacecraft)|PLATO]].<ref name="Wheatley-2017" /> In turn, larger instruments such as HARPS, [[Astronomy:ESPRESSO|ESPRESSO]] and VLT-SPHERE may follow-up on NGTS discoveries with a detailed characterization to measure the mass of a large number of targets using [[Astronomy:Doppler spectroscopy|Doppler spectroscopy]] (wobble method) and make it possible to determine the exoplanet's density, and hence whether it is gaseous or rocky. This detailed characterization allows to fill the gap between Earth-sized planets and [[Astronomy:Gas giant|gas giant]]s as other ground-based surveys can only detect Jupiter-sized exoplanets, and ''Kepler''{{'}}s Earth-sized planets are often too far away or orbit stars too dim to allow for the planet's mass determination. NGTS's wider field of view also enables it to detect a larger number of more-massive planets around brighter stars.<ref name="NGTS Prototyping" /><ref name="sciencemag-2015" />

== Science mission ==
[[File:The Next-Generation Transit Survey (NGTS) at Paranal - Vid.ogg|thumb|left|The Next-Generation Transit Survey (NGTS) searches for transiting exoplanets, i.e. planets that pass in front of their parent star, resulting in a slight dimming of the star's light that can be detected by sensitive instruments. This time-lapse sequence was taken during testing under a bright Moon.]]

Ground-based surveys for extrasolar planets such as WASP and the [[Astronomy:HATNet Project|HATNet Project]] have discovered many large exoplanets, mainly Saturn- and Jupiter-sized gas giants. Space-based missions such as [[Astronomy:CoRoT|CoRoT]] and the ''Kepler'' survey have extended the results to smaller objects, including rocky super-Earth- and Neptune-sized exoplanets.<ref name="Wheatley-2013" /> Orbiting space missions have a higher accuracy of stellar brightness measurement than is possible via ground-based measurements, but they have probed a relatively small region of sky. Unfortunately, most of the smaller candidates orbit stars that are too faint for confirmation by radial-velocity measurements. The masses of these smaller candidate planets are hence either unknown or poorly constrained, such that their bulk composition cannot be estimated.<ref name="Wheatley-2013" />

By focusing on super-Earth- to Neptune-sized targets orbiting cool, small, but bright stars of K and early-M spectral type, over an area considerably larger than that covered by space missions, NGTS is intended to provide prime targets for further scrutiny by telescopes such as the [[Astronomy:Very Large Telescope|Very Large Telescope]] (VLT), European Extremely Large Telescope (E-ELT), and the [[Astronomy:James Webb Space Telescope|James Webb Space Telescope]] (JWST). Such targets are more readily characterized in terms of their atmospheric composition, planetary structure, and evolution than smaller targets orbiting larger stars.<ref name="ngts" />

In follow-up observations by larger telescopes, powerful means will be available to probe the atmospheric composition of exoplanets discovered by NGTS. For example, during secondary eclipse, when the star occults the planet, a comparison between the in-transit and out-of-transit flux allows computation of a difference spectrum representing the thermal emission of the planet.<ref name="NGTS Science" /> Calculation of the transmission spectrum of the planet's atmosphere can be obtained by measuring the small spectral changes in the spectrum of the star that arise during the planet's transit. This technique requires an extremely high signal-to-noise ratio, and has thus far been successfully applied to only a few planets orbiting small, nearby, relatively bright stars, such as [[Astronomy:HD 189733 b|HD 189733 b]] and [[Astronomy:GJ 1214 b|GJ 1214 b]]. NGTS is intended to greatly increase the number of planets that area analyzable using such techniques.<ref name="NGTS Science" /> Simulations of expected NGTS performance reveal the potential of discovering approximately 231 Neptune- and 39 super-Earth-sized planets amenable to detailed spectrographic analysis by the VLT, compared to only 21 Neptune- and 1 super-Earth-sized planets from the ''Kepler'' data.<ref name="Wheatley-2013" />

== Instrument ==

=== Development ===

The scientific goals of the NGTS require being able to detect transits with a precision of 1 mmag at 13th magnitude. Although at ground level this level of accuracy was routinely achievable in narrow-field observations of individual objects, it was unprecedented for a wide-field survey.<ref name="Wheatley-2013" /> To achieve this goal, the designers of the NGTS instruments drew upon an extensive hardware and software heritage from the WASP project, in addition to developing many refinements in prototype systems operating on La Palma during 2009 and 2010, and at the Geneva Observatory from 2012 to 2014.<ref name="NGTS Prototyping" />

=== Telescope array ===

NGTS employs an automated array of twelve 20-centimeter f/2.8 telescopes on independent equatorial mounts and operating at orange to near-infrared wavelengths (600–900&nbsp;nm). It is located at the [[Organization:European Southern Observatory|European Southern Observatory]]'s Paranal Observatory in Chile, a location noted for low water-vapor and excellent photometric conditions.

=== Combined search ===

The NGTS telescope project cooperates closely with ESO's large telescopes. ESO facilities available for follow-up studies include the [[Astronomy:High Accuracy Radial Velocity Planet Searcher|High Accuracy Radial Velocity Planet Searcher]] (HARPS) at La Silla Observatory; [[Astronomy:ESPRESSO|ESPRESSO]] for radial-velocity measurements at the VLT; SPHERE, an adaptive optics system and coronagraphic facility at the VLT that directly images extrasolar planets;<ref name="sphere" /> and a variety of other VLT and planned E-ELT instruments for atmospheric characterization.<ref name="Wheatley-2013" />

== Partnership ==

Although located at Paranal Observatory, NGTS is not in fact operated by ESO, but by a consortium of seven academic institutions from Chile, Germany, Switzerland, and the United Kingdom:<ref name="ngts" />

* [[Organization:University of Chile|University of Chile]]
* [[Organization:University of Leicester|University of Leicester]]
* [[Organization:University of Warwick|University of Warwick]]

== Results ==
* On 31 October 2017, the discovery of [[Astronomy:NGTS-1b|NGTS-1b]], a confirmed [[Astronomy:Hot Jupiter|hot Jupiter]]-sized extrasolar planet orbiting NGTS-1, an [[Astronomy:Red dwarf|M-dwarf star]], about half the mass and radius of the [[Astronomy:Sun|Sun]], every 2.65 days, was reported by the survey team.<ref name="Bayliss-2017" /><ref name="Space.com-2017" /><ref name="Phys.org-2017" /> Daniel Bayliss, of the [[Organization:University of Warwick|University of Warwick]], and lead author of the study describing the discovery of NGTS-1b, stated, "The discovery of NGTS-1b was a complete surprise to us—such massive planets were not thought to exist around such small stars – importantly, our challenge now is to find out how common these types of planets are in the Galaxy, and with the new Next-Generation Transit Survey facility we are well-placed to do just that."<ref name="Phys.org-2017" />
* On 3 September 2018, the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34 day orbit. NGTS-4b has a mass 20.6 ± 3.0 {{Earth mass|link=true}} and radius 3.18 ± 0.26 {{Earth radius|link=true}}, which places it well within the so-called "[[Astronomy:Neptunian desert|Neptunian desert]]". The mean density of the planet (3.45 ± 0.95 g cm<sup>−3</sup>) is consistent with a composition of 100% H2O or a rocky core with a volatile envelope.<ref name="West2018"/>
