The Department of Atomic Energy (DAE) inaugurated the Major Atmospheric Cherenkov Experiment (MACE) Observatory, the largest imaging Cherenkov telescope in Asia and the highest of its kind in the world, situated at an altitude of approximately 4,300 meters in Hanle, Ladakh on October 4. The inauguration was led by Dr. Ajit Kumar Mohanty, Secretary of DAE and Chairman of the Atomic Energy Commission.

Built indigenously by the Bhabha Atomic Research Centre (BARC) with support from ECIL and other Indian industry partners, the MACE telescope stands as a milestone in India’s cosmic-ray research efforts. Its unveiling was a highlight of the DAE’s Platinum Jubilee celebrations, with commemorative plaques being unveiled by Dr. Mohanty, officially marking the observatory’s inauguration.

Ajay Ramesh Sule, Additional Secretary of DAE, emphasized the need to balance tourism with scientific activities within the Hanle Dark Sky Reserve (HDSR) and encouraged young students to pursue careers in science and technology.

Dr. Annapurni Subramaniam, Director of the Indian Institute of Astrophysics (IIA), praised the collaborative efforts between DAE and IIA units that made the project possible. Sajjad Hussain Mufti, Chief Conservator of Forests, UT Ladakh, further emphasized community involvement and the UT Administration’s support for scientific research in the region.

Dr. S. M. Yusuf, Director of BARC’s Physics Group, welcomed attendees and highlighted the significance of the MACE telescope in boosting India’s space and cosmic-ray research capabilities.

The event also featured a pictorial compilation documenting the MACE project’s journey and a screening of a film showcasing the telescope’s scientific and technological milestones. Dr. Mohanty honored local village leaders, school officials, and the Lama of Hanle Gompa during the ceremony.

Concluding the day’s proceedings, dignitaries and attendees were treated to a guided tour of the MACE Observatory and its state-of-the-art control room. The observatory's inauguration places India firmly on the global map of advanced astronomical research.

Dr. K. K. Yadav, Head of BARC’s Astrophysical Sciences Division, delivered the vote of thanks, followed by interactions between the dignitaries and the team of astronomers and technicians responsible for the observatory.

The MACE telescope, capable of observing high-energy gamma rays, marks a significant advancement for Indian astrophysics and cosmic-ray research. Its strategic location will contribute to global efforts to unravel the universe's most energetic phenomena, such as supernovae, black holes, and gamma ray bursts, complementing international observatories and elevating India’s position in multi-messenger astronomy.
