Astronaut Paolo Nespoli lit the tree this year by sending a signal from the Space station, reports Italian national news agency ANSA.
Nespoli sent the signal that lit up more than 460 lights in the 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 at the annual lighting ceremony in Gubbio, 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 and popes.
