About MACE Telescope:

Details
Details and Working World’s highest imaging Cherenkov telescope, located in Hanle, Ladakh, at 4.3 km above sea level.
• It has a 21-meter-wide mirror-dish, the largest in Asia.
Developed by Bhabha Atomic Research Centre (BARC), Tata Institute of Fundamental Research (TIFR), Electronics Corporation of India Ltd. (ECIL), and Indian Institute of Astrophysics (IIA).
Cherenkov radiation is captured using mirrors and analyzed with photomultiplier tubes (PMTs). Cherenkov radiation is the blue glow emitted when charged particles travel faster than light in a medium.
• Equipped with a high-resolution camera and movable base.
Aims and Objectives of MACE Detects high-energy gamma rays (greater than 20 giga-electron volts) emitted by cosmic phenomena.
Detect Weakly Interacting Massive Particles (WIMPs) for dark matter research.
Contribute to multi-messenger astronomy by complementing data from other telescopes.
How Do Gamma Rays Work in DNA Mutation? Cause ionization, which can break chemical bonds in DNA, leading to mutations.
Mutations may result in cancers or genetic disorders if not repaired.
DNA damage from gamma rays can lead to chromosomal aberrations and contribute to carcinogenesis.
