Fundación Galileo Galilei - INAF Telescopio Nazionale Galileo 28°45'14.4N 17°53'20.6W 2387.2m A.S.L.

The "Fundación Galileo Galilei - INAF, Fundación Canaria" (FGG) is a Spanish no-profit institution constituted by "INAF", the Italian Institute of Astrophysics.

The FGG's aim is to promote the astrophysical research, as foreseen in the international agreement of May 26, 1979 ("Acuerdo de Cooperación en Materia de Astrofísica, B.O.E. Núm.161, 6 Jul 1979"), by managing and running the Telescopio Nazionale Galileo (TNG), a 3.58m optical/infrared telescope located in the Island of San Miguel de La Palma, together with its scientific, technical and administrative facilities.

5% International Time Programme is open, deadline 28-02-2023

The International Scientific Committee (CCI) of the Roque de los Muchachos (ORM, La Palma) and Teide (OT, Tenerife) observatories invites applications for the International Time Programme (ITP) on the telescopes installed at these Observatories.

A new approach to reveal the climate of KELT-9b

The exoplanet KELT-9b is predicted to have a permanent, scorching-hot day-side and a permanent cooler night-side due to tidal locking. A new study thanks to HARPS-N data at Telescopio Nazionale Galileo (TNG) and led by Lorenzo Pino (INAF Astrophysical Observatory of Arcetri) in the framework of the GAPS collaboration, allowed to verify this prediction. The study also allowed to observe the effect that the different temperature across the two hemispheres could have on the three-dimensional atmospheric structure and climate of the planet.

The desert of Hot Neptunes

Since the discovery of the first exoplanet around a solar-like star in 1995, researchers have detected more than 5000 planets in our galactic neighborhood, most of them orbiting very close to their star. If the diversity of these new worlds ranges from gas giants the size of Jupiter or Saturn to smaller planets the size of Mercury, including rocky planets larger than the Earth, gas planets the size of Neptune seem to be missing. Astronomers call this empty "space" in the distribution of close-in planets the Hot Neptune Desert.

The WEAVE Archive System (WAS) started its commissioning

WAS, the WEAVE Archive System facility offered by the Telescopio Nazionale Galileo - INAF, started its commissioning on the 17th of January 2023. Data access has been opened to the WEAVE Participants in order to verify its functionality.
