"Planetary Rings" by XKCD comic (Fediverse mirrors @xkcd @xkcdbot ) - Geosynchronous Earth Orbit (GEO), where a #communications #satellite stays above a point on the surface, was theorized in 1929. It took #SciFi writer Arthur C Clarke to popularize the concept in the mid-1940s. Satellites have launched to GEO since the 1950s. They're all still there, too high for atmospheric drag. The ring around the equator is often called the Clarke Belt. https://xkcd.com/3156/ #astronomy #planetary #science

Komabayashi–Ingersoll limit (Climatology 🌍)
In planetary science, the Komabayashi–Ingersoll limit represents the maximum solar flux a planet can handle without a runaway greenhouse effect setting in. For planets with temperature-dependent sources of greenhouse gases such as liquid water and optically thin atmospheres the outgoing longwave radiation cu...

Refractory (planetary science) (Volcanology 🌋)
In planetary science, any material that has a relatively high equilibrium condensation temperature is called refractory. The opposite of refractory is volatile. The refractory group includes elements and compounds like metals and silicates which make up the bulk of the mass of the terrestrial planets and ast...

📸 Titan Shadow Transit
Every 15 years, Saturn’s rings appear edge-on from Earth. The view may be narrow, but it reveals rare transits of Saturn’s moons and their shadows.
In this image from July 18, Titan crosses Saturn’s face, casting a dark round shadow on its cloud tops.
