When A Desert Planet And Ocean Planet Mix: A Saharan Dust Plume
Sandstorms, which are common over the Sahara, occur when large amounts of dust particles from the desert are swept up by strong winds. They can float for days or even […]

Extreme Supersonic Winds Measured On Exoplanet WASP-127b
Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33 000 km/h, the winds make up the fastest jetstream of its […]

An Earth-like Stellar Wind Environment For Proxima Centauri c
A new planet has been recently discovered around Proxima Centauri. With an orbital separation of ∼1.44 au and a minimum mass of about 7 M⊕, Proxima c is a prime […]
