The Baikal underwater telescope NT-200 in Russia has been set up to capture elusive neutrino particles in a bid to unravel the secrets of the formation of the Universe.

At 1.1km beneath the surface of the world's deepest lake and pointing towards the centre of the Earth, it is one of the most unusual telescopes on the planet.

One of the physicists working on the project, Bair Shaibonov spoke about the several weeks each year he spends working on a remote scientific base on the shores of Baikal.
