James Webb Space Telescope (JWST)
Consider the following statements:
- Recently, the James Webb Space Telescope (JWST) provided unprecedented details of the atmosphere of a distant exoplanet, WASP-39 b.
- It is a ‘hot Saturn’ orbiting a star some 1000 light-years away.
- One of the key observations is the first detection in an exoplanet atmosphere of sulfur dioxide (SO2), a molecule produced from chemical reactions triggered by high-energy light from the planet’s parent star.

Photonic Crystal
Consider the following statements:
- Recently, researchers from the Centre for Nano and Soft Sciences (CeNS) have developed soft tunable photonic crystal with enhanced thermal stability and optical purity.
