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 · Neutrinos are subatomic particles with intriguing properties. · They possess no electrical charge and have a very small mass, possibly even zero. · Despite being the most abundant particles in the universe, they interact very weakly with matter. · Neutrinos travel at speeds close to that of light, making them incredibly challenging to detect. Hence, they are often referred to as “ghost particles.” · 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 · The IceCube Neutrino Observatory is a groundbreaking scientific facility located near the Amundsen-Scott South Pole Station in Antarctica. · It is the largest neutrino detector ever built, occupying a cubic kilometre of ice. · The primary objective of IceCube is to observe neutrinos originating from the most violent astrophysical sources, such as supernovae and black holes. · IceCube utilizes strings of digital optical modules (DOMs) embedded in the Antarctic ice to detect the elusive neutrinos. · 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 · The India-based Neutrino Observatory (INO) Project is a significant endeavour aimed at advancing neutrino research. · It involves the construction of an underground laboratory situated in Pottipuram, within the Bodi West hills of the Theni District in Tamil Nadu, India. · The project is jointly funded by the Department of Atomic Energy and the Department of Science and Technology of the Indian government. · Once completed, INO will provide a unique platform for studying neutrinos and advancing our understanding of fundamental particle physics.
