Help scientists unravel the mysteries of Jupiter’s atmosphere

As Futura explained in a previous article, the rise of space travel in the second half of the 20th century wase The 19th century made it possible to transfer the models and techniques of geophysics and geochemistry to other planets in order to carry out comparative planetology and see how the other planets had evolved and structured under different conditions. So it’s a bit like nature being a giant laboratory conducting experiments on the planets under different conditions, allowing us to understand the influence of this and that parameter on the state of a planet when it is varied. We obviously can’t do the same with the earth that would be in a lab where we would do these experiments (to a degree, numerical simulations Where analoguelike experience VKScan, however, help us to understand the planets).

Geophysics and geochemistry are both internal and external and for this reason these sciences do not only apply to the volcano: What is the difference between lava and magma?

Doing comparative planetology therefore also means modeling and understanding the atmospheres VenusMars and gas giants. This, in turn, can help us better understand the Earth and its climate.

All science is based on experimental data and since its inception orbit around Jupiter 2016 the probe Juno of NASA gives us plenty of it. The JunoCam instrument thus delivered gigabytes of images taken during 40 orbits around Jupiter to the noosphere, some taken just a few thousand kilometers above the giant’s atmosphere.

But therein lies the problem, as the postdoc explains in “The theories established by physics apply within well-defined frameworks”.

We need the help of the public to find out what images are there hurricanes, where they are and how they appear.

That’s why he, with his fellow researchers at the University of Minnesota and with the support of NASA, launched a new citizen science project that allows volunteers to play a vital role in helping scientists learn more about the atmosphere to learn about the planet Jupiter. Citizen Scientists can actually help astrophysicist from home and with a short training accessible to all to categorize tens of thousands of amazing images Juno.

A new Zooniverse avatar, Jovian Vortex Hunter

The project was called in English Jovian Vortex Hunter (Whirlwind Hunter jovians) and contains over 60,000 images. He is part of Goal citizen science zoouniverseExtension of the original project Galaxy Zoo invited Internet users to rank galaxies. Futura has already dedicated several articles to this portal, which gives everyone the opportunity to put themselves in the shoes of a researcher at the cutting edge of research, for example by:

The website of Jupiter whirl Hunter (JVH) states: “ Jupiter’s atmosphere is very similar to ours: there are clouds of different shapes and sizes.On Jupiter, most clouds are made up of what is known as the single covalent bond…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/d/0/e/d0e3dc7e1e_76472_molecule .jpg” data -url=”https://news.google.com/sciences/definitions/chemistry-molecule-783/” data-more=”Read more”>molecules other chemicals than water and can measure several thousand kilometers.Some clouds are also created from powerful ones. jpg” data-url=”https://news.google.com/planete/definitions/climatologie-tempete-14551/” data-more=”Read more”>storms more than 50 kilometers high and hundreds of kilometers in diameter.Understanding how these clouds form is very important to understanding Jupiter’s atmosphere and the processes that create the amazing features we see.

The different clouds on Jupiter form under different atmospheric conditions (e.g. storms, whirlpools), similar to how we get different types of clouds when the atmosphere is calm or stormy on Earth.The types of clouds on Jupiter are also highly dependent on the chemical that forms them.Jupiter has three main cloud layers: do not confuse ammonia and ammonia clouds
If you dissolve ammonia gas in water you get ammonium hydroxide,…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/ 9/5/b/95b622c18e_104841_ammonia-factory- fotolia. jpg” data-url=”https://news.google.com/sciences/definitions/chemistry-ammonia-2959/” data-more=”Read more”>ammonia are mostly the ones you can see as they form at the very top, followed by a layer of ammonium hydrosulfide (a key ingredient in stink bombs, so these clouds aren’t the stinkiest!).
Deep in the atmosphere (about 150 kilometers below the ammonia clouds) are thick water clouds.

To understand how these different clouds form, we need to look at the variety of cloud properties in Jupiter’s atmosphere.In this project we will create a catalog and group images from JunoCam into different characteristic classes of the clouds present. »

To help citizen scientists identify atmospheric eddies, the project Jovian Vortex Hunter offers several guides and tutorials helpful video. Each picture is reviewed by at least 16 people. In the end, the catalog is used to feed a network of neuron structures
Each neuron consists of:
