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.

30 Years of the Telescopio Nazionale Galileo in La Palma: creative contests celebrating the Universe

On 29 June 2026, the Telescopio Nazionale Galileo (TNG) will celebrate its 30th anniversary, marking three decades of scientific discovery from the Roque de los Muchachos Observatory in La Palma.

AOT54 Call for Proposals. Deadline submission on Monday May 25th, 12:00 UT

The available time offered in this call at TNG via INAF-TAC is 67 nights, 47 of which are reserved to exo-planetary research programs (see special notices below) and 20 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.

DOLORES gravitational lensing data reveal Milky Way-like stars in a distant galaxy core 8 billion years ago

Spectroscopic observations obtained with the spectrograph DOLORES installed at the Telescopio Nazionale Galileo enabled astronomers to determine the redshift of one of the most distant lensing galaxies known to date. The system, J1453+0529, consists of a quasar at redshift 2.82 whose light is gravitationally lensed by a foreground elliptical galaxy at redshift 1.055. The lens produces a rare quadruple configuration with an extremely small separation between the images. High-resolution imaging clearly shows the four quasar images arranged around the central lensing galaxy (see Figure 1). This configuration allows astronomers to measure the Einstein radius with great precision and determine the total mass enclosed within it, providing strong constraints on the stellar initial mass function in the galaxy’s central region.
