A mysterious phenomenon occurs in the Sun, because contrary to all reasonable logic, the Sun's atmosphere becomes hotter and warmer as it extends farther from the surface of the Sun. l & # 39; star. This is what is called the "hot crown", and it still disconcerts scientists.
Crown temperatures reach about 2 million degrees Fahrenheit, while temperatures in the crown region only exceed 10,000 degrees Fahrenheit. This peculiarity remains the most puzzling situation in astrophysics and scientists have no idea of how this phenomenon occurs.
However, on August 11, 2018, NASA's Parker Solar Probe will launch the mission to fly over the hot crown and recover data and clues. When one looks at the Sun, one sees it unchanged, but the Sun is far from being calm and peaceful because its surface is tormented by frequent solar flares and bursts of radiation that cause huge solar materials to spurt out.
The "hot crown" of the Sun is a mysterious 150-year-old phenomenon that will soon be solved
The atmosphere of the Sun, or crown, stretches for millions of kilometers above the surface of the Sun and is made of plasma and superheated gas that splits into electric ions, free flow and electrons
It all started in 1869, during a total eclipse, when a green spectral line has been observed. By using spectrometers, astronomers can determine the elements of the composition of the Sun, but in 1869, scientists thought that they had found a new element and called it "coronium".
About 70 years later, a Swedish scientist discovered that coronal emissions are caused by iron ionized 13 times because it is overheated. To achieve such a feat, the iron should reach about 2 million degrees Fahrenheit
"I think of the hot corona problem as an umbrella that covers a couple of confusing related problems," said Justin Kasper, an astronomer of the # 39; University. For several decades, coronal heating has remained a mysterious phenomenon, but astronomers are now waiting to solve it as the new NASA's solar probe Parker prepares to examine the Sun's crown
