Nasa\u2019s Juno spacecraft just flew incredibly close to Io, one of Jupiter\u2019s most intense and fascinating moons. And what did it catch? A glowing lava lake so smooth it actually reflects sunlight, like a mirror\u2026 and all of that, placed on a volcanic moon that\u2019s constantly erupting. That\u2019s Loki Patera, and thanks to Juno, we now have the clearest view of it we\u2019ve ever seen.<\/a><\/p>\n

Juno made two ultra-close flybys of Io\u2014one in December 2023 and another in February 2024\u2014flying just 930 miles above the surface. The images and data it sent back are blowing scientists\u2019 minds. Scott Bolton, Juno\u2019s lead scientist, shared the findings this spring at the European Geophysical Union, and to be honest, they sound unreal.<\/p>\n

Io isn\u2019t like Europa, Ganymede, or Callisto, its more chill moon siblings.<\/a> This place is a volcanic hellscape. Juno captured so much more than just glowing rivers of magma: actual plumes of sulfur, clouds of sulfur dioxide, and a surface that reflects light like volcanic obsidian. Yes, obsidian. You know, the black glass stuff that forms from cooling lava on Earth? Io is covered in that, but on a way more massive, alien scale.<\/p>\n

Io\u2019s poles turned out to be colder than its middle latitudes. Somehow, even on a moon full of volcanoes, there are still icy zones. This moon doesn\u2019t play by the rules.<\/p>\n

Loki Patera: a lava lake that literally glows<\/p>\n

Let\u2019s talk about Loki Patera, because it\u2019s honestly wild. It\u2019s not just big\u2014it\u2019s massive. Over 200 kilometers wide. From space, it looks like a huge dark oval. But what Juno saw up close is way cooler: the surface of the lake is so still and shiny, it reflects sunlight back like a sheet of glass.<\/p>\n

That shine tells scientists<\/a> it\u2019s probably formed from rapidly cooling magma, turning into smooth volcanic obsidian. And there are actual \u201cislands\u201d inside the lake. Floating. In lava. Around it, there\u2019s glowing lava at the edges and plumes of sulfur dioxide rising up into Io\u2019s thin atmosphere. It\u2019s basically an alien volcano paradise. Or nightmare. Depends how you feel about standing near rivers of lava.<\/p>\n

Meanwhile, Jupiter\u2019s got some strange storms brewing<\/p>\n

While Juno was capturing Io\u2019s chaos, it also turned its instruments back toward Jupiter, and what it\u2019s finding up there is just as weird. Especially around the north pole.<\/p>\n

It shows up just fine in regular and infrared images, but in the microwave data, it basically fades away. That\u2019s a pretty strong hint that something unusual is going on under the surface, maybe this storm is built differently from the others, or made of something we don\u2019t fully understand yet.<\/p>\n

Each orbit, Juno collects more data, and scientists are slowly building a 3D view of these storms. And the more they see? The more questions they have.<\/p>\n

Still a questions on the horizon: How did the Solar System form?<\/p>\n

One of Juno\u2019s big missions is to figure out how much water is hiding in Jupiter\u2019s atmosphere. It\u2019s not water like oceans or lakes\u2014it\u2019s tiny hydrogen and oxygen molecules buried deep inside Jupiter\u2019s thick atmosphere. figuring out how much of it is there gives scientists clues about how jupiter formed, and even how the whole solar system started coming together billions of years ago.<\/p>\n

Back in the \u201890s, NASA\u2019s Galileo probe dropped into Jupiter and barely found any water, which didn\u2019t make sense. But now we know why. Thanks to Juno, scientists discovered Galileo just landed in a weirdly dry spot. Juno\u2019s data shows that near the equator, Jupiter\u2019s water content is actually three to four times the solar average.<\/p>\n

Jupiter\u2019s core might be way drier than expected and no one really knows why yet. Maybe future Juno flybys around the polar regions\u00a0will help clear things up.<\/p>\n","protected":false},"excerpt":{"rendered":"Nasa\u2019s Juno spacecraft just flew incredibly close to Io, one of Jupiter\u2019s most intense and fascinating moons.
