So today we will introduce you top 10 fact about Google that you may not know.
NASA’s Juno probe has been discovering more about Jupiter Internal Structure than ever before. It is about its internal structure. The $1.1 billion spacecraft, which arrived in orbit around Jupiter in 2016, has been studying variations in the gas giant’s gravitational pull. The probe’s latest discoveries point out that Jupiter’s wind-sculpted bands extend down over 3,000km. That’s on a planet which is 140,000km wide. “This solves a long-time mystery,” said Juno scientist Tristan Guillot. According to him that was all really important for understanding atmospheric dynamics, not just on Jupiter but on other gaseous planets like Saturn, Uranus and Neptune and also the exoplanets they were at that moment discovering. The surface of a planet normally discovers little about the processes at work in the planet’s interior. Jupiter’s surface consists of alternating bright and dark bands of gas that harbor powerful winds. These winds flow in opposite directions and can reach speeds of more than 100 meters per second. Jupiter’s interior is a dense fluid that comprises a mixture of hydrogen and helium. Energy loss from the interior drives convection currents inside the planet that reach up to the surface. A main goal of the NASA Juno mission to Jupiter is to decide which of the frameworks is correct. That is to say such planets are now known to be common in the Galaxy. “It’s generated a bit deeper down when hydrogen becomes so highly compressed that it becomes a metal. And then charges can move easily and you can have, with convection, what’s called a dynamo effect,” said Dr Guillot. Leigh Fletcher, from Leicester University thinks that scientists have been seeking for years to go to Uranus and Neptune, and they were hoping that in the next few years the Americans would put it right at the top of their agenda, after the next mission to Jupiter’s moon Europe. That is to say by the late 2020s or early 2030s they would have a real mission to study those planets. The scientists differentiated their new discoveries in three studies the 8 of March issue in the Journal Nature. To get more information about this topic you can watch the video below:
