For the first time, one of the man-made objects touched the sun

With the arrival of the Parker solar probe on the solar corona, for the first time in history, a man-made object has touched it as the sun's atmosphere enters. NASA's Parker Solar Probe reached the Sun's vast atmosphere, known as the Crown, on April 28, 2021, at 03:33 Eastern Time Zone (12:03 Tehran time). He spent the hour there. This is the first spacecraft to enter the outer borders of our Sun.

The fall of the American Geophysical Union 2021 has been announced. The mission is being led by the Johns Hopkins University Applied Physics Laboratory (JHU/APL). "This indicates the achievement of "The primary goal of the Parker mission is to usher in a new era in understanding the physics of the solar corona."

In this historic event, the probe made the first direct observations of what lies beneath the Sun's atmosphere and closely measured phenomena that had previously only been estimated. The outer edge of the sun starts at the critical level of the Alfvn: the point below which the sun and its gravitational and magnetic forces directly control the solar wind. Many scientists believe that sudden inversions in the sun's magnetic field, known as the "switchback," arise from this area. "The idea of sending a spacecraft into the sun's magnetic atmosphere is as "Soon, when magnetic energy is greater than kinetic energy and heat energy of ions and electrons, it goes back many years." He threw a star. Following Parker's significant record-breaking breakthrough last April, the probe spent five hours below the critical level of Alfonso in direct contact with the Sun's plasma. It was stronger than the pressure and energy of the particles. During its close encounter, the spacecraft flew above and below the surface of the Alfonso three times. This is the first time a spacecraft has entered the solar corona and touched the sun's atmosphere. The data provided by Parker show that the largest and farthest surface wrinkles are created by overnight flow. A large magnetic structure more than 40 degrees wide that is in the innermost visible part of the sun. It is unknown at this time what he will do after leaving the post.

This probe also provides evidence of Recorded the increase in potential power inside the crown, which may indicate unknown physics that affect heating and energy dissipation.

"Light. "We have been observing the sun and its corona for decades and know that there is a lot of physics going on to heat and accelerate the solar plasma," said Nour E. Raouafi, an astrophysicist and scientist at the Parker Solar Exploration Project. "However, we can not say exactly what this physics is," he added. "With the Parker solar probe now flying to the crown under the sun's magnetic field, we will get the expected information about the inner workings of this mysterious region."

. All data in the NASA PSP archive is publicly available. Several previous studies have predicted that the spacecraft will cross the inner solar boundaries for the first time in 2021.

The Parker solar probe, the fastest man-made object, has since launched new discoveries, including New explosions show that direct observations by spacecraft could provide up-to-date information on the physics of corona heating and solar wind formation. . After achieving his goal of touching the sun, Parker now plans to go even deeper into the atmosphere and stay there longer.

According to Gary Zank A joint researcher at SWEAP and a member of the National Academy of Sciences, "the importance of this event and the observations made by the Parker probe can hardly be overstated. For more than 50 years since the beginning of the space age, the heliospheric community has grappled with the unanswered problem of how the solar corona heats up to more than 1 million degrees to move the solar wind.

he noted: "Now the first sub-alphony solar wind measurements may be the biggest step in understanding the physics behind the acceleration of the solar wind since the Parker formation model was determined. "This event is what many solar physicists have dreamed of for most of their working days." Hopkins APL/Naval Research Laboratory
