Comet C/2020 F3 (NEOWISE) is considered the brightest comet in the northern hemisphere since comet C/1995 O1 (Hale-Bopp) in 1997. The perihelion occurred on 3 July, 2020, at a distance of 0.29 AU, and its closest approach to Earth occurred on July 23, 2020, at a distance of 0.69 AU. The unique passage of comet NEOWISE, in combination with the high resolution of HARPS-N (High Accuracy Radial velocity Planet Searcher in North hemisphere), offered a unique opportunity to deeply investigate the...

An international collaboration between scientists of the Istituto Nazionale di Astrofisica (INAF) and the Instituto de Astrofísica de Canarias (IAC), together with other institutions from Spain, Germany, Belgium, UK, and Mexico, has been able to measure the masses of the giant planets of the V1298 Tau system, just 20 million year old. For this result they have used radial velocity measurements from the HARPS-N spectrographs, at the Telescopio Nazionale Galileo, Roque de los Muchachos...

There is a new entry in the growing list of galaxies belonging to the Local Galaxy Group (LG), the system to which the Milky Way belongs. Named Pisces VII/Triangulum III, this new extended source was discovered in September 2020 by the amateur astronomer Giuseppe Donatiello by visual inspection of archival images of the DESI Legacy Imaging Surveys (DESI LIS) and subsequently confirmed by follow-up observations using the Italian Telescopio Nazionale Galileo (TNG). The TNG imaging...

The ashes due to the volcano eruption are making difficult to observe at ORM. The roof of the TNG requires continuous cleaning before opening the dome, to avoid first the ash fall and then the deposit over optics and electronics. For this reason, we reconsidered the time of the upgrade of the Telescope Control System, scheduled on April 2022. Due to the foreseen persistent activity of the volcano, we decided to advance the intervention to November 2021; the TNG will remain closed from...

In the year of the 25th birthday of the TNG, an event will take place in the island of La Palma, from October 19 to 21, 2021. The event is mainly addressed to the Italian astronomical community, with the aim of strengthening the past and current interplay and of emphasizing the future needs. The event will start on October 19 at 10.00 am at the venue, the Hotel H10 Taburiente Playa, Los Cancajos. Limits in the audience have been imposed by the anti Covid-19 restrictions.The work plan was...

On the occasion of the eruption of the volcano on La Palma, the Fundación Galileo Galilei - INAF (FGG) will provide on its website the complete meteorological data of its two stations together with the measurements of suspended dust in 6 channels: 0.3, 0.5, 1.0, 3.0 , 5.0 and 10.0 µm, in the neighbour of the Telescopio Nazionale Galileo (TNG). The dust measurement in µg/m3 is calculated according to the hypothesis of spherical particles and a uniform density of 2.5 g/cm3. Since they are raw...
