The Major Atmospheric Cherenkov Experiment (MACE) Observatory has been inaugurated by Dr. Ajit Kumar Mohanty, Secretary DAE & Chairman of the Atomic Energy Commission, at Hanle, Ladakh, on 4th October 2024. MACE is the largest imaging Cherenkov telescope in Asia. Located at an altitude of ~4,300 m, it is also the highest of its kind in the world. The telescope is indigenously built by BARC with support from ECIL and other Indian industry partners. The inaugural of MACE Observatory was a part of the Platinum Jubilee year celebrations of the DAE. The event commenced with the unveiling of commemorative plaques by Dr. Mohanty at the MACE site at Hanle, Ladakh, thereby officially inaugurating the MACE Observatory.
In his inaugural address, DAE Secretary Dr. Mohanty applauded the collective effort that brought the MACE telescope to fruition. He stated that the MACE Observatory is a monumental achievement for India, and it places our nation at the forefront of cosmic-ray research globally. He further added that this telescope will allow us to study high-energy gamma rays, paving the way for deeper understanding of the universe’s most energetic events. Dr. Mohanty emphasised the significant role that MACE project plays not only in advancing scientific research but also in supporting the socio-economic development of Ladakh. Students were encouraged to explore careers in astronomy and astrophysics, with Dr. Mohanty expressing hope that the MACE project would inspire future generations of Indian astronomers, scientists, and engineers. Dr. Mohanty also paid tribute to India’s pioneering contributions to the field, including the work of Dr. Homi J. Bhabha, whose legacy continues to inspire India’s cosmic-ray research.

A special film on the MACE telescope was screened, showcasing the scientific and technological advancements made during the project. The day concluded with a guided tour of the MACE Observatory, giving attendees an exclusive look at the world-class observatory that establishes India on the global advanced astronomy map.
The inauguration of the MACE telescope marks a significant step forward for Indian astrophysics and cosmic-ray research. Situated at an altitude of ~4,300 m, the MACE telescope will observe high-energy gamma rays, contributing to global efforts to understand the most energetic phenomena in the universe, such as supernovae, black holes, and gamma-ray bursts. This facility will also complement global observatories, strengthening India’s position in the field of multi messenger astronomy.
Looking ahead, the 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.
