It seems that NASA has found the solution about the corona on the Sun.
Our sun is not just a sphere of burning fire. Rather, it is a dense mass of plasma, and the temperature above is … utopian.
However, ever since humanity began to conquer space, the Sun has always been the subject of research. With the necessary expertise and equipment, NASA experts have uncovered a strange truth. That is, although the surface of the Sun has an extremely hot temperature (around 5500 degrees C), but the surrounding atmosphere – also known as corona – is even more terrifying, when the temperature here is high.200- 500 times more than the surface.
This means that, in the corona halo, the temperature can reach millions of degrees Celsius. And that was one of the age-old mysteries of the Sun that NASA had no way of explaining, until the Glass Interface Region Imaging Spectrograph (IRIS) was launched in the space.
According to IRIS data, the corona appears to be “heated” by countless heat bombs inside the Sun. These bombs will emit an enormous amount of energy when they explode. With the magnetic field, this energy source will be kept in the corona halo.
The IRIS telescope is able to analyze both transition regions – the area between the surface of the Sun and the corona. Thus, IRIS can calculate the speed of movement of hot steam with unprecedented precision.
“Because IRIS can analyze the transition region with 10 times the accuracy of previous technology, we can observe a sudden increase in temperature in the Sun, with a magnetic field here” – lead researcher, said Dr Paola Testa from Harvard University.
Since launching into space in 2013, IRIS has acted like a giant lens, allowing us to take a closer look at how the Sun works. And now we’re learning more about the Sun’s magnetic field exploding – thanks to IRIS, of course.
But what is the purpose of this research? According to experts, studying the activity of the Sun will give us information on how long a hurricane can strike the Earth. We know that storms from the sun can destroy communication systems on our planet.
In addition, the process of building a nuclear fusion furnace actually depends on how the Sun works.
Only by capturing the fusion reactions inside the Sun can we successfully develop an infinite form of fuel, yet clean and extremely safe.
