IceCube Neutrino Observatory

Why is it in the news?

  • Scientists at the IceCube Neutrino Observatory in Antarctica have detected seven potential astrophysical tau neutrinos that passed through Earth.
  • Astrophysical neutrinos are high-energy particles originating from the farthest reaches of the universe, and their undisturbed travel over massive distances provides valuable insights into the evolution of the universe.
About Neutrinos

路聽聽聽聽聽聽 Neutrinos are subatomic particles with intriguing properties.

路聽聽聽聽聽聽 They possess no electrical charge and have a very small mass, possibly even zero.

路聽聽聽聽聽聽 Despite being the most abundant particles in the universe, they interact very weakly with matter.

路聽聽聽聽聽聽 Neutrinos travel at speeds close to that of light, making them incredibly challenging to detect. Hence, they are often referred to as “ghost particles.”

路聽聽聽聽聽聽 Neutrinos are produced through various natural processes, such as nuclear reactions in the Sun and particle decays within the Earth, as well as in man-made environments like particle accelerators and nuclear reactors.

About IceCube Neutrino Observatory

路聽聽聽聽聽聽 The IceCube Neutrino Observatory is a groundbreaking scientific facility located near the Amundsen-Scott South Pole Station in Antarctica.

路聽聽聽聽聽聽 It is the largest neutrino detector ever built, occupying a cubic kilometre of ice.

路聽聽聽聽聽聽 The primary objective of IceCube is to observe neutrinos originating from the most violent astrophysical sources, such as supernovae and black holes.

路聽聽聽聽聽聽 IceCube utilizes strings of digital optical modules (DOMs) embedded in the Antarctic ice to detect the elusive neutrinos.

路聽聽聽聽聽聽 In 2013, IceCube made headlines by presenting the first evidence of high-energy astrophysical neutrinos originating from cosmic accelerators.

India-based Neutrino Observatory (INO) Project

路聽聽聽聽聽聽 The India-based Neutrino Observatory (INO) Project is a significant endeavour aimed at advancing neutrino research.

路聽聽聽聽聽聽 It involves the construction of an underground laboratory situated in Pottipuram, within the Bodi West hills of the Theni District in Tamil Nadu, India.

路聽聽聽聽聽聽 The project is jointly funded by the Department of Atomic Energy and the Department of Science and Technology of the Indian government.

路聽聽聽聽聽聽 Once completed, INO will provide a unique platform for studying neutrinos and advancing our understanding of fundamental particle physics.
