A previously never-before-seen magnetic storm not only created the first dramatic “light show” that has been discovered, but has also confirmed long-standing suspicions about the sun,media reported. NASA scientists at the Solar Dynamics Observatory captured the moment a huge ring of superheated matter ejected from the sun’s surface from the SDO sensor and then erupted into a magnetic storm.
For the SDO team, the sun is hardly a stable observation, often seeing huge eruptions of matter, rotating magnetic fields, and so on. But while NASA and other scientists have previously seen magnetic field lines explode and reconnect, this is the first time it has been triggered by an eruption.
This is known as forced reassociation, and researchers have theorized its existence 15 years ago. However, unlike the spontaneous reconnection semods seen before, forced reconnection has proved to be “stubborn” and difficult for sensors to capture. This is mainly because it requires a rare sequence of incidents to occur.
Unlike spontaneous reconnection, which requires certain conditions for current conduction, forced reconnection may occur on more solar surfaces. But unless there is an eruption, it will not be triggered: it will squeeze the plasma and magnetic field until they reconnect. Using SDO’s precise sensors to observe the sun and watch particles heated to a specific wavelength of 1 million to 2 million Kelvin, researchers can track what happens in the corona.
Although it can bring an impressive “light show,” scientists are also excited about the potential impact of the observations on other areas of research. First, it could pave the way for a new understanding of the sun’s weather, especially the way in which solar radiation affects and sometimes causes damage to satellites orbiting the Earth.
In addition, the system can be recreated in the lab using the same process as magnetic reconnection. This could lead researchers to control fusion and plasma in a more stable way, eventually releasing new energy and more energy.
“This is the first observation of an external drive with magnetic recoupling,” said Abhishek Srivastava, a scientist at the Indian Institute of Technology. This can be useful for understanding other systems. For example, the magnetosphere of Earth and planets, as well as other magnetized plasma sources, include experiments on the laboratory scale where plasma is diffuse and difficult to control. “
