We are able to see it during a solar eclipse, or by using a special device called the coronagraph. It is impossible to see the Corona with the naked eye, but there is an exception. It starts at about 1300 miles above the photosphere, and its temperature is measured to be around 900,000 degrees Fahrenheit. this video captures plasma in the suns middle corona at two different temperatures (gold: 1.4 million degrees fahrenheit or 800,000 degrees celsius blue: 2.
There are four outer layers of the Sun, and the Corona is the outermost one. The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone. The layers of the Sun are divided into two larger groups, the outer and the inner layers. position of the axis of the inner corona will, as a rule, at once tell whether the observer was above, below, or in the plane of the Sun's equator. A 'hot' trail to explain this effect leads to a region of the solar. On April 28, 2021, during its eighth flyby of the Sun, Parker Solar Probe encountered the specific magnetic and particle conditions at 18.8 solar radii (around 8.1 million miles) above the solar surface that told scientists it had crossed the Alfvn critical surface for the first time and finally entered the solar atmosphere. However, we can determine the internal structure of the Sun, and it is made up of seven different layers. Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. The full-resolution version of the Sun's corona, as captured by the Solar Orbiter probe, can be viewed online here. Because the Sun is mostly composed of helium and hydrogen and is not solid, it does not have an outer boundary that is clearly defined. The critical difference is that the Sun is not solid, unlike Earth, so the layers are a bit harder to determine.

The long-awaited milestone, which happened in April but was announced on. Learn more about it explore What Causes the Seasons The answer may surprise you. A NASA spacecraft has entered a previously unexplored region of the Solar Systemthe Sun’s outer atmosphere, or corona. Just like our planet, and most other celestial bodies, the Sun is divided into distinct layers. The Sun’s activity follows an 11-year cycle.
