National Large Solar Telescope (NLST): Objectives and Location

Category: Science and Technology / Astronomy

UPSC Notes

The National Large Solar Telescope is a proposed ground-based solar observatory designed to study the Sun's surface, magnetic fields and dynamic atmospheric processes.

The project is associated with the Indian Institute of Astrophysics.

Proposed features

  • A 2-metre-class optical and near-infrared telescope.

  • High-resolution observations of solar magnetic structures.

  • Research into solar flares, waves and other energetic phenomena.

  • Complementary observations to space-based solar missions, including Aditya-L1.

The proposed site is near Merak in Ladakh, close to Pangong Lake, at an altitude of approximately 4,200 metres.

Key Pointers for UPSC

  • Full form: National Large Solar Telescope.

  • Institution: Indian Institute of Astrophysics.

  • Proposed location: Merak, Ladakh.

  • Purpose: Ground-based solar observations.

  • NLST is distinct from Aditya-L1, India's space-based solar observatory.

  • The high-altitude location offers favourable atmospheric transparency for observations.
