[astro-ph.EP] Previous ALMA observations have revealed unexpectedly strong and rapid variations in Titan’s high-altitude equatorial zonal winds, which present a challenge to our understanding of this moon’s atmospheric dynamics.

Zonal Winds In Titan’s Middle Atmosphere From A Stellar Occultation Observed With Keck Adaptive Optics
We present spatially resolved Keck/NIRC2 images of a stellar occultation by Titan on September 5, 2022 and compare them to predictions from concurrent ALMA observations and a suite of General […]

Aerosol Dynamics On Hot Exoplanets: The Role Of Radiation Pressure
Aerosols appear to be ubiquitous in exoplanetary atmospheres. However because our understanding of the physical processes that govern aerosols is incomplete, their presence makes the measurement of atmospheric properties, such […]

Earth And Space Share The Same Turbulence
In a paper published in Geophysical Research Letters, researchers have discovered that the turbulence in the thermosphere exhibits the same physical laws as the wind in the lower atmosphere. Furthermore, […]
