On August 16, NASA published an incredible image of the sun's "explosion." But don't be afraid, experts say that the violent reaction of the sun is almost continuous, and people don't have to worry.
Scientists at the NASA Solar Dynamics Observatory (SDO) used a computer model to generate a view of the solar magnetic field on August 10, 2018. This is a snapshot of the stellar violent nuclear fusion reaction and the solar magnetic view.
“The bright areas of the sun's central area clearly show the concentration of the magnetic field lines; the small active areas on the right edge of the sun (also with magnetic field activity), but to a lesser extent,” NASA wrote in a statement. “This is the dynamic activity of the magnetic drive near the surface of the sun.”
According to LiveScience, the white line represents an electromagnetic eruption that originates from the high-energy interaction between the particles that make up the solar magnetic field and its plasma.
As can be seen from the picture, the energy released by the sun is part of the cause of events such as solar winds and other types of space weather.
According to NASA, Parker will face "barbaric" solar heat and radiation on an epic journey. It will be within 3.8 million miles of the surface of the Sun, seven times more distant from the Sun than the spacecraft Helios 2, which was closest to the Sun. The spacecraft was 27 million miles from the Sun in 1976. The main task of the Parker detector is to analyze the atmosphere of the sun.
Parker detectors must withstand temperatures of nearly 2,500 degrees Fahrenheit to complete their bold mission. To achieve this, the probe will be protected with a special 4.5-inch thick carbon composite shield. However, within the spacecraft, the detector's payload will operate at room temperature.
The detector will orbit the sun at a speed of 690,000 kilometers per hour, the fastest man-made object ever. At this rate, from New York to Tokyo, the time required is "less than a minute."
The sun's sundial can be seen during the total solar eclipse. The Parker detector will provide a lot of valuable data.
The Parker probe is expected to arrive near the sun in November.
The Solar Dynamics Observatory is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. Its atmospheric imaging assembly was built by the Lockheed Martin Solar Astrophysics Laboratory (LMSAL) in Palo Alto, California.
