THIRTY METER TELESCOPE (TMT) (Syllabus: GS Paper 3 – Sci and Tech)

Context: Recently, Indian scientists developed an open-source tool to generate infrared star catalogue for Thirty Meter Telescope.

Thirty Meter Telescope (TMT)

• About: It is a groundbreaking international scientific endeavor aimed at revolutionizing our understanding of the universe.
• Most Advanced Observatory: It will be the world’s most advanced ground-based optical, near-infrared, and mid-infrared observatory.
• Innovative Technologies: The TMT integrates cutting-edge innovations in precision control, segmented mirror design, and adaptive optics.
• Segmented Mirror Design: At its core lies a segmented mirror composed of 492 individual hexagonal segments, which together form a single light-collecting surface.
• Key Features

o Mirror Size: The TMT’s primary mirror, with a diameter of 30 meters, will be the largest in the Northern Hemisphere, surpassing other planned extremely large telescopes.

o Segmented Mirror: The mirror consists of 492 hexagonal segments, each measuring 1.4 meters, working together to create a powerful light-gathering surface.

o Location: Proposed to be built on Mauna Kea, an iconic site on the island of Hawaiʻi, chosen for its high altitude and clear skies, ideal for astronomical observations.

Discoveries

• As the TMT project progresses, it promises to enable groundbreaking discoveries in various fields of astronomy.
• Advanced Technologies: Its segmented mirror technology, adaptive optics, and precise control systems will facilitate unprecedented observations of distant galaxies, exoplanets, and cosmic phenomena.
• India’s Role: India is a key partner in the TMT project, with the India TMT Center at the Indian Institute of Astrophysics (IIA) leading the national collaboration.
