  1. 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.

  2. 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...

  3. Magma ocean (Planetary science 🪐)

    Magma oceans are vast fields of surface magma that exist during periods of a planet's or some natural satellite's accretion when the celestial body is completely or partly molten. In the early Solar System, magma oceans were formed by the melting of planetesimals and planetary impacts. Small planetesimals are melted by ...

    “HIGHLIGHTS:
    • Earth may have had a ring during the middle Ordovician, from ca. 466 Ma.
    • Breakup of an asteroid passing within Earth's Roche limit likely formed the ring.
    • Among several features preserved is a near-equatorial band of impact craters.
    • Shading of Earth by the ring may have triggered a global icehouse period…”

  5. What is Danielle painting? 🤔 Danielle is painting MARS. (Specifically, a HiRise image of amazing folded geological rock formations on Mars. See last post. This is the underpainting.)

    (Where has Danielle been?!? Danielle was working nine days straight. 😵‍💫)

  6. Finished a painting tonight! Presenting “Ice Cliffs of Pluto”, 7x10”, watercolor on cotton.

    I’ve been bogged down in a larger piece I’m working on, so it was delightful to immerse myself in something more textural and abstract. (I’m getting my toothbrush spatter technique down lol.)
