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.

AOT 48 (2023B) is now open for proposals.
AOT48 (2023B): DEADLINE SUBMISSION EXTENSION TO Monday June 5th, 12:00 UT
The available time offered in this call at TNG via INAF-TAC is 104 nights, 75 of which are reserved to exo-planetary research programs (see special notices below) and 29 are for other science programs. We encourage applicants to submit proposals asking a row of consecutive nights to be done in visitor mode. The budget can increase if not all the nights offered in other calls will be effectively allocated by the respective TACs. The foreseen schedule breakdown is reported at the bottom. All proposals will be judged strictly on their scientific merit.
LOCNES Telescope catched its first solar photons
On May 10th, a glorious blue-sky day, the LOw-Cost NIR Extended Solar (LOCNES) telescope saw its first scientific light.
LOCNES is a 2 inch solar telescope installed on the dome of the Telescopio Nazionale Galileo. It feeds the near infrared (NIR) spectrograph GIANO-B with light from the Sun using a patch of 40 m of optical fiber. LOCNES has been designed to obtain high signal-to-noise ratio spectra of the Sun-as-a-star, namely, with no spatial information, as is typically the case for all other stars. This is a completely new area of investigation that will provide timely results to improve the search for telluric planets.
Dolores is out of service
Due to an issue with the CCD detector, DOLORES is not available.
We are working to have it available as soon as possible.
Sorry for the inconvenience.
The smallest planet in an Open Cluster with a precisely measured mass
Radial velocity measurements collected with the HARPS-N and ESPRESSO spectrographs allowed to study the three transiting planets orbiting K2-136, a late-K dwarf (0.742 ± 0.039 MSol) in the Hyades open cluster with three known transiting planets. The analysis of the K2 photometry established that planets K2-136b, c, and d have periods of 8.0, 17.3, and 25.6 d and radii of 1.014 ± 0.050 R⊕, 3.00 ± 0.13 R⊕, and 1.565 ± 0.077 R⊕, respectively. Analyzing HARPS-N and ESPRESSO data jointly, an international team of astronomers led by Andrew Mayo from the University of California, found K2-136c induced a semi-amplitude of 5.49 ± 0.53 m s−1 (Fig. 1), corresponding to a mass of 18.1 ± 1.9 M⊕. They also placed 95% upper mass limits on K2-136b and d of 4.3 and 3.0 M⊕, respectively.
