Webb Telescope's 2026 Haul: Rock-Cloud Planets and a Galaxy That Won't Spin
AI-assisted: summaries and questions may be incomplete or incorrect. Verify important details with the linked original reporting.
Summary
- In 2026 the James Webb Space Telescope watched mineral 'rock clouds' form each morning and vanish by night on the hot-Jupiter exoplanet WASP-94A b, nearly 700 light-years away.
- It found TOI-199b, a Saturn-sized world with surprisingly Earth-like temperatures and a methane-rich atmosphere, and a massive early-universe galaxy showing no rotation at all — challenging formation theories.
- Webb also spotted the most distant 'jellyfish galaxy' yet and a five-galaxy merger just 800 million years after the Big Bang.
The question
The James Webb telescope keeps overturning our assumptions about the early universe.
