NASA’s Parker Solar Exploration, launched in 2018, aims to study the solar corona, the outermost part of the Sun’s atmosphere. This system is breaking new records by crossing the solar atmosphere.

Paths in the solar atmosphere full of discoveries
Because the sun has no surface, the boundary between the solar atmosphere and the planetary space is blurred.. This is called the Alfvén Critical Surface, and it is characterized by point And the sun’s magnetic field cannot retain particles that are constantly pushed outwards Of ‘ . The successive inputs and outflows of the Parker study also show that the Alfven range did not follow a well-rounded ball shape, but rather provided the shapes of ridges and valleys as if its surface were “shrinking”.
In this proximity to the Sun, the study can measure conditions in the solar atmosphere like never before, indicating significant progress in understanding our star. The study, for example, has identified magnetic systems in the “laces” in the solar wind, but still stumbles upon their origin.
With the next paragraph of the corona scheduled for January 2022, this study will continue to be closer and closer to the sun, providing data on events that cannot be explored from Earth.
8.5 million km from the Sun: Parker Solar Study Breaks Distance and Speed Record!
NASA’s Parker Solar probe, launched in 2018, aims to explore, The outer part of the Sun’s atmosphere. After a gravity assist surgery around , Set new records this Sunday at the age of ten , by reaching a 163 kilometers per second (or 586,800 km / h), about 8.5 million kilometers from the Sun.

After a gravitational support operation around Venus, it broke new records in its tenth orbit this Sunday, reaching a speed of 163 kilometers (586,800 km / h) at a distance of about 8, 5 million kilometers from the Sun.
The Has a temperature of one million degrees (a hundred times higher than the surface temperature of the sun). She is in appearance (Flux D ‘ And d ‘ Bombing our planets ) And the mechanisms behind these events are not yet properly understood.
The main purpose of the Parker Solar study is to determine the processes that cause heat in the solar corona and the acceleration of energetic particles. Throughout its measurements, it orbits in an elliptical orbit(The closest point to the center of the orbit) is closest to the sun, and (Point farthest from the center of orbit) In the orbit of Venus. The gravitational effect of the latter is used to gradually reduce the perihelion and allow the study to approach.
Surprising and unexpected discovery
This study was not initially designed to detect grains , But the implications they create in the course of the study format Plasma generating captured electrical discharges The study, initially designed to measure And the magnet of the sun. These impacts are highlighted The presence of a dust cloud rotates in its interior , Still very poorly explored.
After two moreIn 2023 and 2024, Venus will reach a distance of 6.2 million kilometers from the Sun at a speed of 700,000 km per hour.
