World’s Highest Imaging Cherenkov Telescope Unveiled in Ladakh

On October 4, 2024, Dr. Ajit Kumar Mohanty, Secretary of the Department of Atomic Energy (DAE) and Chairman of the Atomic Energy Commission, inaugurated the Major Atmospheric Cherenkov Experiment (MACE) Observatory in Hanle, Ladakh. This monumental facility is the largest imaging Cherenkov telescope in Asia and stands as the highest of its kind in the world, located at an altitude of approximately 4,300 meters.

Built indigenously by the Bhabha Atomic Research Centre (BARC) with support from Electronics Corporation of India Limited (ECIL) and other Indian industry partners, MACE represents a significant achievement in India’s pursuit of advanced astrophysical research. Its inauguration coincides with the Platinum Jubilee celebrations of the DAE, symbolizing a robust commitment to scientific advancement.

Location 

• MACE is situated at around 4,300 meters in Hanle, Ladakh, making it the highest imaging Cherenkov telescope in the world.
• Its elevated position allows for optimal observations of cosmic phenomena free from atmospheric interference.

Focus on High-Energy Gamma Rays

The telescope will primarily observe high-energy gamma rays, providing insights into some of the universe’s most energetic phenomena such as Supernovae, Black Holes, Gamma-Ray Bursts. 

AIM

• MACE project aims to foster international collaborations, advancing India’s contributions to space research and bolstering India’s position in the global scientific community. 
• The observatory will also serve as a beacon of inspiration for future generations of Indian scientists, encouraging them to explore new frontiers in astrophysics.
