Tue Nov 26 00:00:00 UTC 2024: ## India Unveils World’s Highest Gamma-Ray Telescope in Ladakh
**Leh, Ladakh, India –** India has inaugurated the Major Atmospheric Cherenkov Experiment (MACE) telescope, the world’s highest-altitude imaging Cherenkov telescope, located at 4.3 km above sea level in Hanle, Ladakh. This state-of-the-art facility, a collaborative effort between several Indian research institutions, boasts a 21-meter-wide dish – the largest in Asia and second-largest globally.
MACE is designed to detect high-energy gamma rays, elusive emissions from some of the most energetic objects in the universe, such as black holes and pulsars. These gamma rays, possessing energy exceeding 20 billion electron volts, are blocked by Earth’s atmosphere, necessitating ground-based indirect detection methods. MACE utilizes the Cherenkov radiation – faint blue light produced when gamma rays interact with atmospheric molecules – to achieve this.
The telescope’s innovative honeycomb mirror design, similar to that of the James Webb Space Telescope, enhances light collection and stability. Its sophisticated camera system, composed of 1,088 photomultiplier tubes, amplifies the weak Cherenkov signals for analysis. The 180-tonne telescope, mounted on a six-wheeled base, can rotate to observe any part of the sky.
MACE’s primary scientific goals include studying high-energy gamma rays emitted near black holes and other celestial phenomena, and searching for evidence of weakly interacting massive particles (WIMPs), a potential component of dark matter. Its location at high altitude minimizes atmospheric interference, further enhancing its observational capabilities.
The successful development and deployment of MACE represent a significant milestone for Indian gamma-ray astronomy, demonstrating the country’s growing expertise in high-energy astrophysics and particle physics. The project is expected to yield crucial insights into fundamental questions about the universe’s composition and evolution.
