Webb Telescope captures weather patterns on exoplanet WASP-94A b, 700 lightyears away
The NASA James Webb Space Telescope (JWST) has successfully captured weather patterns on exoplanet WASP-94A b, located nearly 700 lightyears away. This 'hot Jupiter' exoplanet, almost twice Jupiter's size but half its mass, is tidally locked to its parent star, resulting in extreme temperature differences between its dayside and nightside. Scientists used spectroscopy to analyze its atmosphere, revealing clouds of magnesium silicate, iron, and magnesium sulphide on its mornings, dissipating by evening. This discovery, published in Science, provides insights into extreme weather cycles and helps astronomers understand planetary formation and evolution across different solar systems.
मुख्य बिंदु
- The James Webb Space Telescope (JWST) observed weather patterns on exoplanet WASP-94A b, 700 lightyears away.
- WASP-94A b is a 'hot Jupiter' exoplanet, tidally locked, with extreme temperature variations.
- Spectroscopy revealed clouds of magnesium silicate, iron, and magnesium sulphide on the planet's morning side, which dissipate by evening.
