Astronaut Paolo Nespoli lit the tree this year by sending a signal from the space station where he has been stationed since July 2017, reports Italian national news agency ANSA.
Nespoli sent the signal that lit up more than 460 lights in the southwest slope of Monte Ingino. "As beautiful as it is being in space, this evening I would have liked to have been there with you to enjoy the show," Nespoli said via video recording at the annual lighting ceremony in Gubbio, Central Italy, on December 7th.
The project uses more than 460 lights, 8,500 metres of cable and is 650 metres high, states the official website dedicated to the tree. It began in 1981.

More than 50 volunteers put in over 2,000 hours of work to set up the tree this year, adds ANSA.
In the past, the tree has been lit by actors (Terence Hill), popes (Pope Francis, Pope Benedict XVI) and members of international aid organizations (Save the Children, Doctors Without Borders).
