Himalayan Chandra Telescope | UPSC
Workshop to mark 20 years of Himalayan Chandra Telescope to highlight the science it produced
WHY IN NEWS:
Himalayan Chandra Telescope (HCT) has been used in many coordinated international campaigns to monitor stellar explosions, comets, and exo-planets, and has contributed significantly to these studies
SYLLABUS COVERED: GS 3: Science and Technology
For PRELIMS note down the key features and the components . UPSC is fond of picking such questions #anniversaries.
HIMALAYAN CHANDRA TELESCOPE
- The Himalayan Chandra Telescope is a 2.01 meters (6.5 feet) diameter optical-infrared telescope .
- It is named after India-born Nobel laureate Subrahmanyam Chandrasekhar.
- It contains a modified Ritchey-Chretien system with a primary mirror made of ULE ceramic which is designed to withstand low temperatures it experiences.
- The area of research covers a wide range of topics, from solar system objects to cosmology.
The telescope is mounted with 3 science instruments:
- Himalaya Faint Object Spectrograph (HFOSC)
- The near-IR imager and
- The optical CCD imager.
- This allows Himalayan Chandra Telescope operation even in sub-zero temperatures in winter.
- It is placed in the cold, dry desert of Ladakh, 4500 meters above the mean sea level at the Indian Astronomical Observatory (IAO) .
- Hosakote is about 35 km northeast of Bangalore.

KEY RESEARCH AREAS
- Study of solar system bodies like; comets, asteroids etc. and young stellar objects.
- Study of open and globular clusters and variable stars in them, abundance analysis of elements in the atmosphere of evolved stars.
- The telescope has been used in many coordinated international campaigns to monitor stellar explosions, comets, and exo-planets.
- HCT has provided data that has been used in the Ph.D. of 40 students.
- Currently, 36 students are pursuing Ph.D. degree, are collecting data with the HCT.
- Building, maintaining, and effective scientific use of the HCT has given our observational astronomy community a great experience.
- It also boosts confidence to be the creators and international partners in the best of next-gen optical telescopes.
- To mark the 20 years of the first light event of the 2m HCT, IIA has organized a two-day online science workshop during September 29-30, 2020.
