The universe remains one of the most mysterious things for humanity. For years scientists have tried to explore all its secrets, but there are many things that still need to be understood. NASA is making huge progresses, and the probe sent to Jupiter, Juno, is one of them.
Nevertheless, even NASA might get some surprising results. For example, this probe is supposed to offer important information until 2022. Juno is in the Jupiter orbit, 5,000 km above the cloud tops of the planet.
The probe is already delivering information about the planet. At the moment, Juno is analyzing things like magnetic fields, atmosphere, core and gravity. NASA was able to discover quite a few things about the composition of the planet.
Jupiter is in fact quite similar with a star, and that is because it is mostly made out of helium and hydrogen. Scientists also say that if this planet would have been way larger, it would have been in fact even more similar with a star, as it would have started thermonuclear burning.
Scientists were actually surprised by some of the findings. For example, they discovered that Jupiter has numerous heavy elements. The planet even has sulphur, carbon, oxygen, nitrogen and iron, and these are only the common elements. The probe also found rare elements, including krypton, argon and xenon. The Juno probe allowed researchers to understand how the heavy elements are distributed.
The atmosphere contains metallic hydrogen and molecular hydrogen. One of the astronomers from France’s Observatoire de la Côte d’Azur is a co-investigator for Juno and he explained certain details. For example, scientists are not yet sure whether the mass core of Jupiter is a 15 to 20 earth mass core one, or if there is none at all.
