Astronomers Map First 3D Atmosphere of Distant Exoplanet WASP-121b

‘Never observed before’: Wedding cake structure surrounding ultra-hot planet

It is so ferociously hot that the “exoplanet” features iron in the form of a gas in one layer of its atmosphere, while a jet stream moves at 70,000 km/h in another.

A Planet 900 Light-Years Away Has Weather So Extreme "It Feels Like Science Fiction". It's 70,000 km/h Winds Carry Vaporized Iron and Even Titanium

Scientists have for the first time mapped the 3D structure of an exoplanet’s atmosphere, uncovering violent winds and bizarre weather patterns.

In A First, Astronomers Reveal 3D Structure Of Alien Planet's Atmosphere

Astronomers for the first time have deciphered the three-dimensional structure of the atmosphere of a planet beyond our solar system.

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.

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 [...]
