Baikal-GVD (Gigaton Volume Detector):


Context:

Russian scientists recently launched one of the world’s biggest underwater neutrino telescopes called the Baikal-GVD (Gigaton Volume Detector) in the waters of Lake Baikail, the world’s deepest lake situated in Siberia.

About Baikal- GVD:

  • It is one of the three largest neutrino detectors in the world along with the IceCube at the South Pole and ANTARES in the Mediterranean Sea.
  • It seeks to study in detail the elusive fundamental particles called neutrinos and to possibly determine their sources.

What are neutrinos?

Neutrinos, first proposed by Swiss scientist Wolfgang Pauli in 1930, are the second most widely occurring particle in the universe, only second to photons, the particle which makes up light. In fact, neutrinos are so abundant among us that every second, there are more than 100 trillion of them passing right through each of us — we never even notice them.

Need for studying:

Studying this will aid scientists’ understanding of the origins of the universe since some neutrinos were formed during the Big Bang, others continue to be formed as a result of supernova explosions or because of nuclear reactions in the Sun.
