Q6.Launched on 25th December, 2021, James Webb Space Telescope has been much in the news since then. What are its unique features which make it superior to its predecessor Space Telescopes ? What are the key goals of this mission ? What potential benefits does it hold for the human race?

The James Webb Space Telescope (JWST), launched on December 25, 2021, is a groundbreaking observatory designed to revolutionize our understanding of the universe. It represents a significant technological and scientific leap over its predecessors.

• Infrared Capability & Mirror: Optimized for infrared, its 6.5-meter gold-coated mirror (larger than Hubble's) penetrates cosmic dust and detects red-shifted light, acting as a 'time machine' to the early universe.
• Massive Sunshield: A five-layer, tennis-court-sized sunshield passively cools instruments to near absolute zero, crucial for faint infrared signal detection.
• L2 Lagrange Point Orbit: Positioned 1.5 million km from Earth, this stable, cold environment minimizes thermal interference for uninterrupted cosmic views.

• Observe the first stars and galaxies formed after the Big Bang.
• Study the formation and evolution of galaxies and stellar systems.
• Characterize exoplanets and search for biosignatures, crucial for understanding planetary habitability.

• Deeper understanding of the universe's origins, evolution, and fundamental laws.
• Potential discovery of extraterrestrial life.
• Technological spin-offs and advancements across various fields.
• Inspiration for future generations in STEM and fostering international scientific collaboration.

JWST is more than a telescope; it is humanity's most ambitious eye on the universe. Its discoveries promise to rewrite textbooks and profoundly deepen our understanding of existence itself.
