Martian craters are more than scars — they're windows into buried glaciers and subsurface secrets. And we don’t even need to land to see it. #MarsScience #PlanetaryGeology #Craters

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…”

graphic - close up of rocks / asteroids making up the rings around Saturn

maps - Areas of continental crust distal to the equator during the Ordovician. Areas older than Ordovician are indicated in salmon colour, Ordovician rocks are dark blue, and younger are in grey. Light blue indicates lakes in Africa. The labelled point (L) in Africa is the Luizi impact structure, which has a very poorly defined age that could plausibly be Ordovician, constrained to be between 0 and 573 Ma

map - Positions of the Ordovician impact craters on the reconstructed plate positions of the MER21 model, showing the movement of continents and trace of impact sites from 467 to 450 Ma. AMZ, Amazonia; ANT, Antarctica; AS, Arabian Shield; AUS, Australia; AZ, Azania; BAL, Baltica; IND, India; LAU, Laurentia; NC, North China; SA, Southern Africa; SAH, Saharah; SC, South China; SEA, South-eastern South America; SIB, Siberia; SSA, Southern South America; T, Tarim; WAF, West Africa.

maps - Areas of continental crust proximal to the equator during the Ordovician. Areas older than Ordovician are indicated in salmon colour, Ordovician rocks are dark blue, and younger are grey. Light blue indicates lakes in Europe and Russia. The labelled pink points are the recognised Ordovician impact spike craters: in Australia, Lawn Hill (LH); in North America, Tunnunik (T), Pilot (P), Lac Couture (LC), East Clearwater Lake (ECw), La Moinerie (LM), Charlevoix (Ch), Brent (B), Slate Islands (SI), Rock Elm (RE), Decorah (D), Calvin (Ca), Glasford (G), Ames (A); in Europe, Lochne (Lo), Malingen (M), Granby (G), Tvaren (T), Hummeln (H), Ilyinets (Iy) and Kardla (Ka) (the latter two are situated on the western edge of the map for Russia). The labelled black points are impact structures with very poorly defined ages that could plausibly be Ordovician in age (Parisi et al., 2024; Schmieder and Kring, 2020), but have not been included in [their] considerations: Goyder (Gy), Glikson (Gl), Matt Wilson (M), Woodleigh (W), Liverpool (L), Glover Bluff (GB), Crooked Creek (CC), Santa Fe (SF), Holleford (H), Île Rouleau (IR), Presqu’île (P), Lumparn (L), Saarijärvi (Sj), Summanen (Sm), Kamenetsk (K), Ramgarh (R).

A really cool and interesting thing just happened in space. NASA’s Mars Rover drove over a rock that cracked open, revealing pure sulfur.

This is a first on Mars. It’s also unexpected given the characteristics of its surroundings.

The crumbles of a rock that’s been crushed. Its red surface is blended with chunks of yellow sulfur.

Accidentally exposed yellowish-green crystals reveal ‘mind-blowing’ finding on #Mars, scientists say

‘The #CuriosityRover has made its most unusual find to date on Mars: rocks made of pure sulfur. And it all began when the 1-ton rover happened to drive over a rock and crack it open, revealing yellowish-green crystals never spotted before on the red planet.’

The rock that the NASA Curiosity rover happened to drive over and crack open, revealing yellow crystals on May 30. It is a jagged and smooshed mix of externally orange-brown rock with the insides showing a broken jumble of yellow rock with bits of green and white.

A really big volcano appears to have been lurking unnoticed on Mars.

' The newfound volcano is 450 kilometers (280 miles) wide and, even eroded as it is, reaches elevations of more than 9 kilometers (close to 30,000 feet). It dwarfs Earth’s largest volcano, Mauna Loa, which is 8 km tall from seafloor to summit, and spans 120 kilometers on its largest side. Mars, however, tends to have larger volcanos .. '

Earth mass (Earth 🌍)

An Earth mass (denoted as M E {\displaystyle M_{\mathrm {E} }} or M ⊕ {\displaystyle M_{\oplus }}, where 🜨 is the standard astronomical symbol for Earth), is a unit of mass equal to the mass of the planet Earth. The current best estimate for the mass of Earth is M🜨 = 5.9722×1024 kg, with a relative uncertainty of 10−4. It is equivalent to an average density of 5...

Cryovolcano (Volcanology 🌋)

A cryovolcano is a type of volcano that erupts volatiles such as water, ammonia or methane into an extremely cold environment that is at or below their freezing point. The process of formation is known as cryovolcanism. Collectively called cryomagma, cryolava or ice-volcanic melt, these substances are usually liquids and can form plumes, but can also be in vapour form. After th...

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.

A watercolor painting with a pinkish rusty background that has a slight steel blue sheen. The color granulates and is more concentrated in splotches across the paper, giving an organic sunspot look. Alternating dark and light banded rock formations are inked in a loose, scribbled texture in two shades of dark navy and blue.

Alternating dark and light banded rock formations are inked in a loose, scribbled texture in two shades of dark navy and blue. Two fountain pens sit beside a black and white photo of these Martian formations.

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. 😵‍💫)

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.)
