It also gives researchers a glimpse into "phenomena that are impossible to study from afar," the release said. The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K. Aside from being an awesome thing to do, the Parker Solar Probe’s mission to touch the Sun revealed new insights about solar wind and its magnetic field. Corona - The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). Researchers published their findings in the journal Physical Review Letters on Tuesday. "Parker Solar Probe ‘touching the Sun’ is a monumental moment for solar science and a truly remarkable feat," Thomas Zurbuchen, associate admin of NASA’s Science Mission Directorate, said in a NASA press release. It actually made its momentous flight in April, but it took months for the data to relay back to Earth and for researchers to confirm their findings, which they announced at a meeting of the American Geophysical Union on Tuesday. NASA has officially acknowledged that its Parker Solar Probe dipped below the upper part of the Sun's atmosphere known as the corona and "touched the Sun," in the agency's phrasing. The corona can be seen only during solar eclipses, when the main radiation from the Sun's surface is blocked by the passage of the Moon or with special instruments. Cracking the CoronaĪ NASA probe has done the seemingly impossible and “touched” the Sun. The corona has been found to emit X-ray radiation (the corona is a plasma at temperatures greater than a million degrees a plasma will radiate a lot of X-rays). 12, 2022 Researchers have discovered web-like plasma structures in the Suns middle corona. The first implementation of this technique in solar physics helioseismology is connected with solar surface oscillations, discovered by Robert. The whole range of ionization of an atom can be found: for example, oxygen I (neutral) is found in the photosphere, oxygen II through VI (one to five electrons removed) in the chromosphere, and oxygen VII and VIII in the corona. During periods of quiet, the corona is more or less confined to the equatorial regions, with coronal holes covering the polar regions. The corona is not always evenly distributed across the surface of the Sun. The probe's data gives NASA insight into previously unobservable phenomena. When astronomers observe the Sun from space at ultraviolet wavelengths, the chromosphere is found to emit lines formed at high temperatures, spanning the range from 10,000 to 1,000,000 K. The outer edges of the Sun's corona are constantly being transported away due to open magnetic flux and hence generating the solar wind.
