29,412 objects are tracked in orbit, yet Mercury's shrinkage captures our gaze.

Satellite data shows Mercury's diameter is decreasing rapidly, a puzzle for planetary scientists. It turns out, the cooling planet is shrinking from within, losing up to 14 km in diameter over time.

Our tools reveal these changes in detail, reshaping our understanding. Explore at [OrbitalRadar](https://orbitalradar.com/satellite-eye).

“Developed in cooperation with the European Space Agency (ESA), PLAYMOBIL brings the excitement of space exploration straight into children’s rooms! Two astronauts have landed safely on the Red Planet with their research rocket – ready to collect soil samples and bring them back to Earth! The rocket features a modular design: it can be extended or shortened, depending on the mission, and docks onto a mobile landing platform that serves as a base station on Mars. Movable crane arms help collect the soil samples and securely store them inside the rocket – either in the front storage compartment or in the rocket-shaped nose cone, ready for launch. The rocket includes seats for both astronauts. Prepare for liftoff – the next PLAYMOBIL research mission is about to begin!..”

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.

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...

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…”

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.

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.’

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...

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.)
