Jupiter is approaching Earth with a terrible heat wave (video)

Jupiter will be closer to Earth on Sunday, September 25, than at any time in 59 years (since 1963), at a distance of approximately 591.2 million kilometers, according to NASA, so those interested will have a unique opportunity to observe in the coming evenings, it is Already the brightest object in the sky after the sun and moon.

In fact, on Monday the Sun, Earth, and Jupiter will be nearly perfectly aligned, in an event that occurs every 13 months called opposition to Jupiter. Then Jupiter gradually moves away from our planet and appears fainter and fainter.

The diameter of Jupiter is approximately 11 times the diameter of the Earth, and it measures 142,984 km, while a complete revolution around the Sun takes about 12 years (that is the length of its year). On the other hand, one revolution around itself (the length of its day) takes only ten hours, which is an astonishing speed for such a large planet.

Among other things, Jupiter has a faint ring system of countless dust particles and – like Earth – a magnetic field, a huge doughnut-shaped belt of electrically charged particles orbiting the planet. Among the approximately 80 satellites of various sizes, the largest and most famous, discovered by Galileo 412 years ago, are Io, Europa, Ganymede and Callisto.

Scientists have detected an unexpected “heat wave” with a temperature of 700 degrees Celsius and a length of 130,000 kilometers – nearly ten times the diameter of the Earth – in the atmosphere of Jupiter, the largest planet in our solar system. James O’Donoghue of Japan’s space agency, JAXA, made a related announcement at the “Europlanet Science Conference” in Granada, Spain.

Jupiter’s atmosphere, famous for its distinctive colorful storms, is also surprisingly hot, hundreds of degrees higher than theoretical models predict. The gas giant planet is located hundreds of millions of kilometers from the sun and receives only 4% of solar radiation compared to Earth. So, in theory, the upper atmosphere should be minus 70 degrees Celsius, but clouds at its summit have been measured at more than 400 degrees for reasons that aren’t clear.

Like Earth, Jupiter has auroras at its poles due to the solar wind. But while the aurora borealis on Earth are temporary and only occur when there is intense solar activity, the aurora borealis on Jupiter are permanent and of varying intensity. Scientists believe that the aurora borealis is the possible mechanism that explains the high temperatures in the atmosphere around Jupiter’s poles.

Then strong winds blow to spread this hot heat around the planet. Scientists’ observations show that the amazing “heat wave” travels at a speed of thousands of kilometers per hour around Jupiter.
