The circle around the Sun is called the corona. The Parker Solar Probe spacecraft flew a short distance from Corona.
This happened in April. But the data has been analyzed and determined now.
Despite the intense heat and radiation from the Sun, Parker gained many new perspectives on the motion and performance of the Sun.
“Setting foot on the Moon helped us understand how it formed. As we get closer to the Sun, we can see how our largest star affects the Solar System.
What is the Parker Solar Probe?
The Parker Solar Probe mission is one of NASA’s most daring space missions.
It was sent into space three years ago. Its goal is to orbit the Sun as often as possible and to get as close as possible.
The spacecraft travels at a speed of 5.00,000 km per hour. moving at higher speeds.
Its strategy is to orbit the Sun and return quickly, measuring the sun’s atmosphere with instruments mounted behind a thick heat shield.
On April 28 this year, Parker crossed the ‘River Critical Boundary’. This is the outer edge of the Corona. Solar matter attached to the Sun by gravitational and magnetic forces divides near this circle and penetrates the universe.
13 million km from the Sun’s surface or photosphere. In height, Parker crossed this circle.
In fact, the data indicate that the probe traveled above and below the Sun’s boundary at three separate times over a five-hour period, said Stuart Bell of the University of California, Berkeley.
“The atmosphere around the Sun has changed significantly. The Sun’s magnetic field inside the coronary ring has become so strong that it controls the movement of particles there. That is, the probe moves around objects closer to the Sun.”
Researchers are more interested in the corona ring. Because there are some important processes going on which are so complicated.
One of these is overheating. The temperature of the Sun in the photosphere is about 6,000C. But in the corona circle it can reach a few lakh degrees more than that.
The outward stream of electrons, protons and heavy ions in this region is unusually diverted in supersonic air. How this happens is still a mystery.
“There are physical effects of this process in the solar wind, but the problem is that the wind erases all these impressions as it enters Earth’s corona, so it travels in orbit. That’s really what’s happening there,” he explained. Noor Rufi from the Johns Hopkins Applied Physics Laboratory. ,
The Parker Science team will collect details on the investigation and future research into the corona.
By 2025, Parker will be closer to the Sun, at an altitude of 70 million km from the photosphere.
The research Parker is doing is important to all people living on Earth.
The biggest explosion from the Sun can damage the Earth’s magnetic field.
Communication can be completely destroyed in the process. All satellites can be turned off. All power grids are at risk of explosion.
Scientists are trying to predict a similar “storm”. As part of this, Parker hopes to provide them with valuable, up-to-date information.
