You can help astronomers discover the secrets of Jupiter!

As Futura explained in a previous article, the rise ofastronautics during the second half of the 20th centuryme century allowed the models and techniques of geophysics and geochemistry to be transposed to other planets in order to carry out comparative planetology and see how the other planets had evolved and had been structured under different conditions. Therefore, it is a bit as if nature were a gigantic laboratory that has experiments in various conditions with the planets, which allows us to understand the influence of this or that parameter on the state of a planet when it is varied. Obviously we can’t do the same with the Earth that would be in a laboratory where we would do these experiments (to some extent, numerical simulations or analog, such as experience VKShowever, it can help us understand the planets).

Geophysics and geochemistry are both internal and external and that is why these sciences are not only applied to the Volcano: what is the difference between lava and magma?

Therefore, doing comparative planetology also means modeling and understanding the atmospheres of VenusMars and gas giants. In turn, this can help us better understand the Earth and its climate.

All science is based on experimental data and since its inception orbit about Jupiter in 2016, the probe June NASA provides us with large amounts of it. The JunoCam instrument thus delivered to the Noosphere gigabytes of images taken during 40 orbits around Jupiter, some of which were taken a few thousand kilometers above the giant’s atmosphere.

However, that is the problem, as the postdoctoral researcher explains in Established theories of physics are applied within well-defined frameworks.

We need the public’s help to identify which images have whirlwinds, where they are and how they appear.

“.

That is why, together with his fellow researchers at the University of Minnesota and with the support of NASA, he has created a new citizen science project that allows volunteers to play an important role in helping scientists learn more about the atmosphere of the planet. planet. Jupiter. Citizen scientists can help astrophysicists from home, and with a brief training available to everyone, to categorize tens of thousands of amazing images taken from June.

A new Zooniverse avatar, Jovian Vortex Hunter

The project was called in English. Jovian Vortex Hunter (whirlwind chaser jovians) and contains more than 60,000 images. he is part of gate citizen science zoouniverseexpansion of the original project galaxy zoo that invited Internet users to classify the 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 forefront of research by becoming, for example:

the website of Jovian Vortex Hunter (JVH) explains: “ Jupiter’s atmosphere is very similar to ours: there are clouds of different shapes and sizes.On Jupiter, most clouds are made up of so-called single covalent bonds…” 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 chemicals other than water and can measure several thousand kilometers.Some clouds are also built from powerful There are no specific features for…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/b/9/7/b97fffc285_117970_tempete-littoral . 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.

Different clouds on Jupiter form under different atmospheric conditions (eg, storms, eddies), similar to how we get different types of clouds when the atmosphere is calm or stormy on Earth.Jupiter’s cloud types also depend heavily on the chemical that forms them.Jupiter has three main cloud layers: Don’t confuse ammonia and ammonia clouds
When 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 they’re mostly the ones you can see as they form at the top, followed by a layer of ammonium hydrosulfide (a key ingredient in stink bombs, so those clouds aren’t the stinkiest!).
Deep in the atmosphere (about 150 kilometers below the ammonia clouds) are thick clouds of water.

To understand how these different clouds form, we need to look at the diversity of cloud characteristics in the Jovian atmosphere.In this project, we will create a catalog and group JunoCam images into different characteristic classes of the clouds present.. »

To help citizen scientists identify atmospheric vortices, the project Jovian Vortex Hunter offers various guides and tutorials helpful video. Each image will be reviewed by at least 16 people. In the end, the catalog will serve to feed a network of Structure of neurons
