Russian scientists on Saturday launched one of the world’s biggest underwater space telescopes to peer deep into the universe from the pristine waters of Lake Baikal.
The deep underwater telescope, which has been under construction since 2015, is designed to observe neutrinos, the smallest particles currently known.
Dubbed Baikal-GVD, the telescope was submerged to a depth of 750-1,300 meters, around four kilometers from the lake’s shore. Neutrinos are very hard to detect and water is an effective medium for doing so.
“A neutrino telescope measuring half a cubic kilometer is situated right under our feet,” Dmitry Naumov of the Joint Institute for Nuclear Research told AFP while standing on the lake’s frozen surface.
