Jakarta –
The European space agency, that is the European Space Agency (ESA), captured the appearance of the sun from a close distance. The surface image was recorded during the launch of the Solar Orbiter vehicle on September 23, 2023.
The Solar Orbiter was flown to record the activity of the Sun’s atmospheric layer or what is commonly known as the corona. This operation was successfully immortalized in a 30 second video, as reported by IFL Science.
Then, on October 7, 2023, the Solar Orbiter found the closest distance to the Sun, which is 43 million km. This distance is about one third of the distance from the Earth to the Sun.
Not only the European space agency, the American country with NASA’s Parker Solar Probe also took views of the sun. The two groups then worked together.
Parker measures particles and magnetic fields in the Sun’s corona and solar wind, so Solar Orbiter monitors the region where the solar wind flows past Parker.
The movement of the sun’s corona is similar to water moss
From the results of observations, the solar corona can experience interesting changes. In the video, the movement of the corona appears to resemble water and moss.
The moss-like movement of the corona at the base of the coronal curve is a plasma pattern. The structure extends far above the surface of the sun.
A peak of plasma can be seen extending from the chromosphere to the upper corona of the Sun. The distance of plasma movement can reach 10,000 km.
Some of the plasma cools and falls back down in dark high-density plumes called “water”. This happens because of gravity.
The rain that occurs is called coronal rain. In addition, there are many spectacular eruptions that seem to be the process of releasing many articles into the solar system.
What is Solar Corona?
For detikers who still don’t understand what the solar corona is, according to the NASA page, the solar corona is the outermost part of the sun’s atmosphere.
The corona is usually obscured by the bright light of the Sun’s surface. Therefore, the human eye cannot see the layers directly except during a total solar eclipse.
The crown temperature is very high. However, scientists still cannot estimate what the temperature will be.
The corona is also 10 million times denser than the surface of the Sun. This density makes the corona less bright than the surface of the sun.
Based on NASA’s IRIS mission, it was discovered that there was a package of very hot material called a “hot bomb”. This bundle of hot material moves from the Sun towards the corona.
When it reaches the corona, the heat bomb explodes and releases its energy in the form of heat as well. According to astronomers, this activity is a way to heat the corona.
For detikers who want to know in detail what the solar corona looks like, you can watch the full video here it is.
