The Major Atmospheric Cherenkov Experiment (MACE) observatory, Asia's largest imaging Cherenkov telescope, was inaugurated in Ladakh's Hanle at an altitude of nearly 4,300 metres. Built by the Bhabha Atomic Research Centre (BARC), it is the highest of its kind globally.
The MACE telescope was constructed indigenously with support from Indian industry partners, including Electronics Corporation of India Ltd (ECIL). Its design and construction are key milestones in India's advanced cosmic ray research capabilities.
MACE will enable scientists to observe high-energy gamma rays that originate from some of the universe's most energetic phenomena, such as supernovae, black holes, and gamma-ray bursts. This is expected to boost India's standing in global cosmic ray research.
The telescope measures 21 metres in diameter, weighs 175 tonnes, and features a reflector area of 356 square metres made up of over 1,400 diamond-turned metallic mirrors. It includes state-of-the-art electronics designed for low-power, low-temperature operations in harsh conditions.
While gamma rays cannot reach Earth's surface, they interact with the atmosphere, producing high-energy particles that emit Cherenkov radiation. MACE’s mirrors and cameras capture these flashes, tracing them back to their cosmic origins.
Hanle, located in Ladakh, was chosen for its exceptionally low light pollution, dry climate, and clear skies. The site offers an ideal environment for gamma-ray observations, providing an observational advantage compared to other global locations.
The success of MACE has the potential to make Hanle a global hub for gamma-ray astronomy. India is positioning itself as a leader in the field, with opportunities for international collaborations and further telescope installations.
Even before its official inauguration, MACE detected gamma-ray flares from objects 200 million light years away, highlighting its capabilities and the scientific potential of this high-altitude observatory.
