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.

The TNG surpasses the wall of 100 papers/year

For the first time in its 24-year activity, the TNG reached and got over the mark of 100 papers published in peer-reviewed journals in one year. The total for 2022 amounts to 105 papers, 24 more than in 2021 and 18 more than the previous record of 87 in 2019. The figure shows the number of published papers since 2000: we count about 1200 papers with an evident increasing trend in the last years.

The OPTICON call for TransNational Access in Semester 2023B is OPEN and will close on 10th March 2023

We are pleased to announce that the 2023B call for observing time at optical/IR telescopes supported via OPTICON-Radionet Pilot project is now open. The call will close on 10th March 2023 at 23.59 UT. The Telescopio Nazionale Galileo offers 10 nights from October 1st, 2023 to March 31st, 2024.

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.
