K-U ratio (Volcanology 🌋)
The K/U Ratio is the ratio of a slightly volatile element, potassium, to a highly refractory element, uranium. It is a useful way to measure the presence of volatile elements on planetary surfaces. The K/U ratio helps explain the evolution of the planetary system and the origin of Earth's Moon.

Dungey Cycle (Planetary science 🪐)
The Dungey cycle, officially proposed by James Dungey in 1961, is a phenomenon that explains interactions between a planet's magnetosphere and solar wind. Dungey originally proposed a cyclic behavior of magnetic reconnection between Earth's magnetosphere and flux of solar wind. This reconnection explained previously observed dynamics withi...

The end of 2025 must be the end of the inane rule of climate ‘optimism’
We should admit that widely-mandated climate optimism has been actively harmful to the needful acknowledgement of reality - and to the active collective self-protection that we now desperately need to get serious about making happen.

"Ecological myopia interprets #climatechange as an environmental problem rather than a #planetary one. It assumes climate sits in a box labelled environment/sustainability while the rest of social & economic life sits in separate silos. This is short sighted."

Kontext "Verbrenner-aus". eine sogen. Journalistin des WDR sagt eben im Radio: "naja 10% CO2 sind ja nicht so viel". Angesichts des drohenden Kollapses der planetaren Systeme, der Wirtschaft, der Zivilisation ist das eine unfassbar schlimme Aussage im öffentlich-rechtlichen Radio. #planetaryCrisis

Planet (Planetary science 🪐)
A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself. The Solar System has eight planets by the most restrictive definition of the term: the terrestrial planets Mercury, Venus, Earth, and Mars, and the giant planets Jupiter, Satu...

Based on extrapolations from other #planetary systems, #Uranus’ electron #radiation belt was off the charts. Since then, scientists have wondered how the #Uranian system could support such an intense trapped #electron radiation belt, at a #planet unlike anything else in the #solar system.

Planetary radius measurements in literature have uncertainties about 40% larger than we measure in this work.
John Southworth, a co-author of this paper, used the revised stellar parameters, and in some cases did new fitting of #TESS lightcurves, and found that our measurements were more precise than those found in the literature.
The attached plot shows the revised #exoplanet radius and mass, along with the difference between ours and those in #TEPCat (https://www.astro.keele.ac.uk/jkt/tepcat/).
