Merak Village, Ladakh:
The Solar is the harbinger of life on Earth, however we perceive so little of our nearest star. The Solar often will get very indignant; it then unleashes huge photo voltaic storms that take down or burn satellites and digital tools on Earth. To trace the Solar, India seeks to arrange the Nationwide Massive Photo voltaic Telescope (NLST) in Ladakh.
Spearheading the undertaking is professor Annapurni Subramaniam, Director of Indian Institute of Astrophysics (IIA), Bengaluru, who says website characterisation has been undertaken and land has been acquired. Solely the ultimate clearance is required for this huge and much-needed undertaking to get off the bottom. It’s virtually a decade late.
In keeping with the IIA, the Nationwide Massive Photo voltaic Telescope can be a two-metre class optical and close to infra-red (IR) observational facility. It’s designed to handle an array of key scientific points associated to the origin and dynamics of photo voltaic magnetic fields at a spatial decision of 0.1-0.3 arc-second.
The instrument has a broad scope to help and substantiate the multitude of photo voltaic atmospheric observations from the space-based Aditya L1 satellite tv for pc mission and ground-based photo voltaic telescope in Rajasthan’s Udaipur.
In keeping with IIA, photo voltaic storms or Coronal Mass Ejections are giant expulsions of billions of tons of plasma and its related magnetic fields from the Solar into the interplanetary area, a few of which may hit the Earth and produce geomagnetic storms. Excessive geomagnetic storms have the potential to hurt space-technology dependent human life on Earth, corresponding to disrupting radio communication, GPS alerts, and so forth. Predicting these storms is a crucial space of scientific analysis at IIA and lots of different establishments in India as properly.

The telescope is to be put in on the banks of the Pangong Tso Lake in Merak, Ladakh, at an altitude of round 4,200 metres. Being a high-altitude chilly desert, this location is greatest fitted to optical and close to IR observations. The positioning offers vital durations of clear skies with excessive transparency. The laminar winds with gentle gusts all through the day present durations of excellent readability.
The Nationwide Massive Photo voltaic Telescope was to be the ground-based counterpart to ISRO’s space-based photo voltaic observatory, the Aditya L-1 satellite tv for pc.
Dr Subramaniam says it so occurs the satellite tv for pc is already in orbit and offering outcomes whereas the NLST received delayed. She provides if all goes properly, very quickly the approvals will come by and the telescope could come up in just a few years. The telescope undertaking will value upwards of Rs 150 crore.
Finding the telescope on the banks of the large Pangong Tso Lake has many benefits – the water physique gives a calmer ambiance to make sharper observations and the continual breeze may also assist preserve the devices cool since photo voltaic telescopes are inclined to warmth up very quick.
The Workplace of the Principal Scientific Advisor not too long ago introduced out a doc ‘Mega Science Imaginative and prescient – 2035’ the place it says “the NLST would be the largest photo voltaic telescope within the nation. We advocate this as the best precedence undertaking in photo voltaic astronomy.”
On July 6, 2024, India’s Principal Scientific Advisor Ajay Ok Sood visited the positioning of the photo voltaic telescope and took inventory of the developments. “The area is understood for its exceptionally clear skies and low gentle air pollution, making it a superb location for stargazing.”
