Io's atmospheric oxygen atoms are heated by atmospheric sputtering and escape from Io's gravity, forming a neutral oxygen cloud around Io's orbit. This neutral cloud is important as a source of the Io oxygen plasma torus. Previous studies derived ...

Molecular cold gas and star formation have been observed at centers of
cool-core clusters, albeit at a level much smaller than expected from the
classic cooling model. Feedback from the supermassive black hole is likely to
have prevented hot gas f...

Planetary-scale waves at the Venusian cloud-top cause periodic variations in
both winds and ultraviolet (UV) brightness. While the wave candidates are the
4-day Kelvin wave and 5-day Rossby wave with zonal wavenumber 1, their temporal
evolutions a...
