Merak Village, Ladakh:
The Sun is the harbinger of life on Earth, however we perceive so little of our nearest star. The Sun sometimes will get very offended; it then unleashes large photo voltaic storms that take down or burn satellites and digital gear on Earth. To observe the Sun, India seeks to arrange the National Large Solar Telescope (NLST) in Ladakh.
Spearheading the challenge is professor Annapurni Subramaniam, Director of Indian Institute of Astrophysics (IIA), Bengaluru, who says website characterisation has been undertaken and land has been acquired. Only the ultimate clearance is required for this large and much-needed challenge to get off the bottom. It is nearly a decade late.
According to the IIA, the National Large Solar Telescope might be a two-metre class optical and close to infra-red (IR) observational facility. It is designed to deal with 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 assist 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.
According to IIA, photo voltaic storms or Coronal Mass Ejections are massive expulsions of billions of tons of plasma and its related magnetic fields from the Sun into the interplanetary area, a few of which may hit the Earth and produce geomagnetic storms. Extreme geomagnetic storms have the potential to hurt space-technology dependent human life on Earth, similar to disrupting radio communication, GPS indicators, and so forth. Predicting these storms is a vital space of scientific analysis at IIA and plenty 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 finest fitted to optical and close to IR observations. The website gives important intervals of clear skies with excessive transparency. The laminar winds with delicate gusts all through the day present intervals of excellent readability.
The National Large Solar 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 obtained delayed. She provides if all goes properly, very quickly the approvals will come via and the telescope could come up in a couple of years. The telescope challenge will price upwards of Rs 150 crore.
Locating the telescope on the banks of the large Pangong Tso Lake has many benefits – the water physique provides a calmer environment to make sharper observations and the continual breeze will even assist maintain the devices cool since photo voltaic telescopes are inclined to warmth up very quick.
The Office of the Principal Scientific Advisor just lately introduced out a doc ‘Mega Science Vision – 2035’ the place it says “the NLST would be the largest photo voltaic telescope within the nation. We advocate this as the very best precedence challenge in photo voltaic astronomy.”
On July 6, 2024, India’s Principal Scientific Advisor Ajay Ok Sood visited the location of the photo voltaic telescope and took inventory of the developments. “The area is understood for its exceptionally clear skies and low mild air pollution, making it a wonderful location for stargazing.”
