In the context of modern scientific research, consider the following statements about ‘IceCube’, a particle detector located at South Pole, which was recently in the news:
- 1.It is the world’s largest neutrino detector, encompassing a cubic kilometre of ice.
- 2.It is a powerful telescope to search for dark matter.
- 3.It is buried deep in the ice.
Which of the statements given above is/are correct?
- A.1 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3 only
▶ Answer & Explanation
Correct answer: D. 1, 2 and 3 only
The IceCube Neutrino Observatory is indeed the largest neutrino detector globally, utilizing a cubic kilometer of Antarctic ice. It operates as a telescope, with a significant goal being the detection of high-energy neutrinos originating from astrophysical sources, which can also indirectly aid in the search for dark matter candidates. The detector's sensors are embedded deep within the ice sheet to minimize interference from other particles and maximize the detection of neutrinos.
