Mind-blowing weather found in exoplanet's atmosphere

WASP-121b is a gaseous, giant exoplanet located some 900 light-years away in the constellation Puppis. Its atmosphere, which is divided into 3 layers, has never been seen before on any planet. Credit: ESO/M. Kornmesser Astronomers have peered into the atmosphere of an exoplanet some 900 light-years away and found powerful weather patterns that make the most severe storms in the Solar System seem like a calm breeze. “It feels like something out o…

From Metal Rain to Roaring Jet Streams: The First 3D Look at an Alien Atmosphere

Astronomers have unlocked a new way to explore alien worlds by mapping the 3D structure of an exoplanet’s atmosphere for the first time. Using ESO’s Very Large Telescope, they discovered extreme winds carrying iron and titanium across the skies of WASP-121b, an ultra-hot gas giant orbiting its star at a breakneck pace. The planet’s jet [...]

'Out of science fiction': First 3D observations of an exoplanet's atmosphere reveal a unique climate

Astronomers have peered through the atmosphere of a planet beyond the Solar System, mapping its 3D structure for the first time. By combining all four telescope units of the European Southern Observatory's Very Large Telescope (ESO's VLT), they found powerful winds carrying chemical elements like iron and titanium, creating intricate weather patterns across the planet's atmosphere. The discovery opens the door for detailed studies of the chemica…
