Atmosphere (Planetary science 🪐)

An atmosphere is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. The name originates from Ancient Greek ἀτμός 'vapour, steam' and σφαῖρα 'sphere'. An object acquires most of its atmosphere during its primordial epoch, either by accretion of matter or by outgassing of volatiles. The chemical interaction of the atmosphere with the so...

Planetary science (Planetary science 🪐)

Planetary science is the scientific study of planets, celestial bodies and planetary systems and the processes of their formation. It studies objects ranging in sizes from micrometeoroids to huge gas giants, with the aim of determining their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, which originally grew from a...

Jupiter in a Lab

The vivid bands of a gas giant like Jupiter come from the planet’s combination of rotation and convection. It’s possible to create the same effect in a lab by rapidly spinning a tank of water around a central ice core. That’s the physical set-up behind this research poster–note the illustration in the lower right corner. The central snapshots show how temperature gradients on the water surface change the faster the tank rotates. At higher rotational speeds, the parabolic water surface gets ever steeper and Jupiter-like temperature bands form. (Image credit: C. David et al.)

Here is a direct link to what went to someone's BlueSky account before. It is about Neptune's supposedly black ice core and how that affects its magnetism.

Even if this turns out to be wrong, it is so wild that I want it to be true.

We Finally Know What Jupiter’s Core Looks Like
NASA’s Juno mission has shattered our expectations of the Gas Giant’s interior. Instead of a solid rocky heart, Jupiter possesses a "fuzzy" or dilute core that gradually blends into its hydrogen layers. This "dilute core" suggests a violent history of massive planetary collisions that permanently scrambled the planet's innards.

A systematic analysis has identified approximately 400 bright slope streaks, or "lineae," on #Mercury , indicating the #planet is currently geologically active through the outgassing of subsurface volatiles.

#PPOD: These observations of Jupiter’s auroras were captured with JWST's Near-InfraRed Camera (NIRCam) on 25 December 2023 (F335M filter). Scientists found that the emission from the trihydrogen cation, H3+, is far more variable than previously believed. H3+ is created by the impact of high-energy electrons on molecular hydrogen.

Three panels, each showing a close-up near-infrared image of Jupiter’s north pole, in shades of orange. The planet is mostly dark. Thick, bright arcs and rings caused by aurorae cover the pole. The three panels each show the aurora a few minutes later in time - left to right, they are labelled “08:15:00”, “09:10:00” and “09:55:00”.

Extraterrestrial sample curation (Planetary science 🪐)

The curation of extraterrestrial samples obtained by sample-return missions takes place at facilities specially designed to preserve both the sample integrity and protect the Earth. Astromaterials are classified as either non-restricted or restricted, depending on the nature of the Solar S...
