TNG :: Telescopio Nazionale Galileo

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.

Telescopio Nazionale Galileo Leads the Discovery of a Super-Earth in the Habitable Zone of a Nearby Red Dwarf

2025/03/12

An international team of astronomers, using the HARPS-N spectrograph on the Telescopio Nazionale Galileo (TNG) at Roque de los Muchachos Observatory, La Palma, has made a groundbreaking discovery: a new super-Earth orbiting in the habitable zone of the nearby red dwarf star GJ 3998, located just 59 light-years away. This planet, named GJ 3998 d, is the third planet found in this system, further highlighting the critical role of the TNG in advancing the search for exoplanets.

HARPS-N and the two Mini-Neptunes in resonant orbit around the star TOI-1803

2025/03/07

TOI-1803 is an orange star located 388 light years away from the Sun with a mass of 76% of the mass of the Sun. The star hosts two Neptune-sized planets named TOI-1803 b and TOI-1803 c, which reside in an orbital configuration close to a 2:1 mean motion resonance. In particular TOI-1803 b orbits the star every ~6.3 days, while TOI-1803 c has a period of ~12.9 days. The discovery of such a resonance is of great interest as it provides insights into planetary migration and the dynamical evolution of exoplanetary systems.

First on-sky tests of the optical and near-infrared cameras for the upcoming eSiFAP fast photometer

2025/02/24

The "eSiFAP" is a next-generation instrument for simultaneous optical and near-infrared (J and H bands) fast photometry, an enhanced version of SiFAP2, mounted at the Nasmyth A focus of the Telescopio Nazionale Galileo (TNG).

The TNG observations of asteroid 2024 YR4, currently on the top of ESA/NASA impact risk list

2025/02/19

Asteroid 2024 YR4 is currently on the top of ESA NEOCC risk list. Discovered on 27 December 2024 by the ATLAS survey in Chile, it has increased its chances of an impact on Earth in 2032, to the point where it has currently reached a 2.4% impact probability, and a level 3 on the Torino impact scale. Though it still has a very small chance of impacting Earth on 22 December 2032, the situation is currently monitored by several observatories around the world. Further observations indeed can remove YR4 from the risk list, and assess its physical properties.
