Waiting for [#JUICE ...] NASA's #Juno probe recently took images of the surface of #Europe, an icy moon of #Jupiter. And what a surprise! The #ice crust has shifted, distorted, ...
So what happened? Are these changes the result of interactions with the vast oceanic area lying beneath Europa's surface?
Citizen scientist Gerald Eichstädt made these images using raw data from the JunoCam instrument, applying processing techniques to enhance the clarity of the images.

「 By combining the imaging power of lots of smaller telescopes scattered across a plateau, ALMA is able to spot regional differences in the presence of specific elements in Io's atmosphere, as well as identify different isotopes of those elements 」
#Jupiter’s icy moon #Europa generates 1,000 tons of #oxygen every 24 hours – enough to keep a million humans breathing for a day. Charged, or ionized, particles from Jupiter bombard the icy 🧊 surface, splitting water 💦 molecules in two to generate oxygen that might find its way into the moon’s ocean. NASA’s #EuropaClipper mission will determine if Europa has conditions that could be suitable for life 🦠 https://www.jpl.nasa.gov/news/nasas-juno-mission-measures-oxygen-production-at-europa
I was today years old when I learned #Juno. It has a 10x better experience than using Safari for YouTube!
@christianselig feedback: because the subs video list is quite noisy and I don't have time to watch every one of them most of the time, I use the "subbed channels" list at the sidebar a lot to quickly filter out the subs video list. I believe Juno doesn't have it, tho I understand this probably isn't something everyone uses, so no worries if you don't have a plan for it
@christianselig I’ve been loving #Juno! Thanks for making it. If I could make two tiny feature requests, I’d love support for both SponsorBlock and DeArrow. 🙏
The Jupiter moon Io - captured by the Juno spacecraft during Perijove 58.
The angle of the sun during this flyby created stunning specular reflections on the basalt covered lava lake of Loki Patera.
🛰️🟡 Ce 3 février, la sonde #Juno de la NASA a effectué un nouveau survol de la lune #Io de #Jupiter à une distance au plus près de 1500 km.
Voici l'une des premières images acheminées vers la Terre montrant la surface de la lune volcanique :
Juno's close flyby of Io on Dec 30 shortened its orbital period around Jupiter from 38 earth days to 35 days. The recent flyby of Io on Feb 3 further shortened it to 33 days.
Also, as shown below, each passing orbit increases the latitude where Perijove occurs, which also increases the time spent in Jupiter's ferocious radiation belts, risking damage to spacecraft electronics.
