Explosions on Sun: How do magnetic explosions happen on the Sun’s surface? NASA solves 60 year old mystery

Washington: Scientists of the US space agency NASA have solved the mystery of the magnetic explosion on the Sun. Through this it will now be known how explosions occur on the Sun. Not only this, scientists will also be able to predict geomagnetic explosions and solar flares affecting the Earth. An explosion process called magnetic reconnection produces solar flares. These solar flares are so powerful that in a few minutes their number emanating from the Sun can produce enough energy to power the entire Earth for 20 years.

It took scientists 60 years to understand the process
NASA scientists have spent more than 60 years understanding this process. After which the team of NASA’s Magnetospheric Multiscale Mission (MMS) has developed a theory that explains how magnetic reconnection occurs and how it maintains the same speed continuously. There are several types of magnetic reconnection. A special variant of this is known as fast reconnection. Due to this, the understanding of scientists about the Sun is expected to increase further in the coming days. NASA scientists are completely confident about doing something new in the future regarding this principle.

what is magnetic reconnection
Magnetic reconnection is called magnetic reconnection in Hindi. This is a process that takes place in plasma. This rapidly ejects an energetic, fluid-like material from the Sun’s surface, which is highly sensitive to magnetic fields. From being born on the Sun, to near-Earth space, black holes and plasma throughout the universe undergo magnetic reconnection, which rapidly converts magnetic energy into heat and acceleration.

“We’ve known for some time that fast reconnection happens at a fixed rate, which seems pretty constant,” said Barbara Giles, MMS project scientist and research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. That rate has been a mystery until now. New research, published in a paper in the journal Nature Communications Physics, describes how fast magnetic reconnection occurs specifically in a collisionless plasma. Collisionless plasma is a type whose particles are so spread that they do not collide with each other.

Scientists proved the theory
The NASA team has also shown to prove this theory using a common magnetic effect called the Hall Effect. The Hall effect is a common magnetic phenomenon, used in Jamra’s technique. For example, speed sensors of vehicles, 3D printers, where the sensors measure speed, proximity, position or electric current.
