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.

Young astronomers

"The second phase of the "Young Astronomers and Telescopio Nazionale Galileo" Competition has just concluded. Launched last November in its first edition, it has just completed its second phase, which saw the six winners together with their tutors experience an astronomical internship at Telescopio Nazionale Galileo (TNG), under the supervision of Gloria Andreuzzi, TNG staff and responsible of the competition on behalf of INAF (Istituto Nazionale di Astrofisica) and TNG. The six students Italo Grasso, Leonardo Karol Iaquinto, Chiara Izzo, Emanuele Morone, Fabio Pascale, and Annalisa Vitelli from Liceo Scientifico I.I.S. Telesio di Telese Terme (BN), along with their teacher Antonio Pepe, their INAF tutor Vincenzo Testa (Osservatorio Astronomico di Roma) who followed them during the preparation of the proposal and the observations and Elisa di Carlo, responsible for the competition by SAIT (Società Astronomica Italiana), reached the island of La Palma last Saturday, May 4th.

Telescopio Nazionale Galileo helps to detect a magnetar giant flare in M 82

On 2023, November 15, at 15:36:22 UT the European Space Agency (ESA) INTEGRAL satellite detected a short (about 0.1 second duration) flash of gamma-ray radiation from the nearby galaxy M 82 (12 million light years).

AOT 50 (2024B) is now open for proposals.

HARPS-N and the sub-Neptune HD 77946 b

The principal investigator of this project, L. Palethorpe, together with her team, used high-precision radial velocity measurements from HARPS-N together with transit observations from NASA's TESS satellite and ESA's CHEOPS satellite to characterise a sub-Neptune around the star HD 77946 (Mstar = 1.17 Msun , Rstar = 1.31 Rsun). They found that HD 77946 b has a mass of 8.38 ± 1.32 Earth masses and a radius of 2.71 ± 0.09 Earth radii, placing it into the region of mass-radius space where there is confusion about its possible composition.
