The video taken by the European Space Agency’s (ESA) Solar Orbiter near the sun has been released.
The IT media Gizmodo reported on the 2nd (local time) the solar atmosphere imaged by the Extreme Ultraviolet Observer (EUI) instrument mounted on the Solar Orbiter.
The video was shot on September 27 last year, and at the time of filming, the spacecraft was at 0.33 AU, or about a third of the distance between the Earth and the Sun.

This is a very close distance to the Sun, but the Solar Orbiter plans to approach the Sun at a distance of at least 43 million km (about 0.287 AU) on October 7, so it is expected that we will be able to see the Sun very closer in the future.
In the published video you can see the dynamic appearance of the sun. Hair-like structures made of plasma, or charged gas, represent magnetic field lines emanating from the Sun’s interior. ESA explained that the temperature of the brightest spot visible in the image is around 1 million degrees Celsius, and the dark spot is an area where radiation is absorbed.

At the bottom left you can see a lacy pattern created by the glowing gas known as “corona moss.” It is known that these patterns are found mainly on the bottom of large crown rings. Along the solar horizon are towering spiers of gas known as spicules, which extend about 100,000 km into the chromospheres, the lowest layers of the solar atmosphere.

You can also see a small explosion in the center. Media reported that it is actually a larger-than-Earth explosion, showing cold material rising upwards and then mostly falling back down.
According to ESA, on the day this video was recorded, NASA’s Parker Solar Probe came within 7.26 million km of the sun’s surface and measured particles and magnetic fields in the solar corona and solar wind. Gizmodo commented that in the future there will be opportunities for collaboration between the remote sensing equipment of the ESA-led Solar Orbiter and NASA’s Parker Probe.
