Interesting world of sun
At this time, the mercury of heat has become very high. The sun is spewing fire. But a new mysterious thing in this world of the sun has been discovered. The world of sun is quite interesting and many types of research are being done about this.
Actually, it has come to light that small loops are hidden in solar corona. Before understanding what this small loop is first, it is important to understand what the solar corona is. The solar corona is the top layer of the sun, which is spread out of the sun surface. This layer is very thin, but extremely hot. Its mercury is up to 10 million degrees Celsius.
Small loops world
A new discovery has revealed that there is a bright world of small plasma loops in the lower layers of the sun's atmosphere. They are so small that they are still hidden. However, he has a clue of one of the deepest mysteries of the sun – which tells how the sun stores and releases magnetic energy.
However, the sun looks stable to our eyes, less dense, but quite dynamic environment behind the sun's shining surface, which is made of plasma.
Temperature of 10 million degrees
The most interesting characteristics of the outer layer of the sun are coronal loops, hot plasma -arc -like structures that glow at temperatures above 1 million degrees. While research on these large loops in solar corona or outer atmosphere has been done for a long time, scientists are now also paying attention to small parts of these loops.
How big mini loops?
These mini loops are about 3,000–4,000 km long (almost the distance from Kashmir to Kanyakumari). However, their width is less than 100 kilometers. This makes research on them even more challenges. Actually, it is hidden in the lower layers of the Sun's atmosphere, due to which it becomes difficult to do research on them.
The Astronomers and his colleagues of the Indian Institute of Astro Physics (IIA) (IIA) (IIA), K. Astronomers and his colleagues used high-resolution imaging and spectroscopy to do research on this interesting world. Annu Bura said PhD student Annu Bura in IIA, said, these small loops die very quickly. Are, when it comes to understanding the sun, these loops are more than their weight.
The team used state -of -the -art telescopes to check these small scale coronal loops. He collected data from Good Solar Telescope, NASA interface Region Imaging Spectrograph (IRIS) and Solar Dynamics Observatory (SDO) to detect these loops.
H-alpha spectral line from hydrogen atoms is an important line for the solar chromosphere check, which is present right above the visual surface of the sun. The team found that red, or long wavelength, in the line, these loops appear as shining, delicate arcs like a coronal loop.
Rising temperature inside loops
An attempt was made to understand the temperature of the plasma inside these loops. The results showed that the temperature of the plasma was rising above several million degrees. Which could be seen in SDO's atmospheric imaging assembly.
