Close up images of the Sun's surface taken by the probe

This image is a close-up image of the Sun's surface taken by the probe. This image was taken by the Solar Orbiter on May 30, 2020, when it was only 77 million kilometers away from the Sun. The wavelength used is in the extreme ultraviolet band, so it shows a picture of the coronal region, a feature of the Sun that we cannot see with the naked eye.

From this angle, we can feel that the sun is not as calm as we think, while those small bright spots are called glow, they are similar to the sun's flare bursts, but glow bursts are much smaller, of course, this small is only relative to the sun. So it seems that the seemingly small glow is a horrible existence, and the surface of the sun is filled with such small bursts of energy everywhere.

We just started to see that image is the detector with extreme ultraviolet band photographed solar features, which is the band we can not see with the naked eye, then the naked eye visible solar surface and what is it?

This picture is the probe at the same distance with visible light photographed at the surface of the sun, that is, the structure of the photosphere, so this is the closest to the human eye to see the surface of the sun, compared to the extreme ultraviolet band, visible light photographed the surface of the sun is much milder, but if you pull the lens closer, this seemingly mild surface, but also full of boiling and violent.

This image was released in January 2021 and is the best image of the sun's surface taken to date. The sun is a giant sphere composed of plasma, so it has the characteristics of fluid, so the surface of the sun can flow like a fluid. Of course, the fluid here is made up of plasma with a temperature of 6000 degrees Celsius, which is not something we can just touch.

The fluid characteristic combined with the temperature difference, so on the surface of the sun formed the organization called the rice grain. The grain of rice tissue is created by the temperature difference created by the convection of the plasma. When the plasma rises, the temperature is high, so it appears brighter. When the plasma is falling, the temperature is low, so the brightness appears darker. So in this mechanism, we see the rice grain feature on the surface of the sun, a tumbling soup of plasma.

In addition to the rice-grain tissue, we can also see with the naked eye the black structure, and when the plasma soup on the surface of the Sun passes through a strong magnetic field, they are confined by the strong magnetic field, which makes temperature lower than the temperature of the surrounding plasma. So we have this dark area for the naked eye, and this image is a photograph of a sunspot in detail. The diameter of this sunspot is about 16,000 kilometers, such a diameter can easily fit an Earth, but on the surface of the Sun, it is a small black dot, this is the Sun's photosphere layer some features, in the photosphere layer, there are chromosphere and coronal structure, below, there is the tropospheric radiation region and the core.

The sunlight we see radiates from the core of the sun, which is the core of the sun. The solar core is where the nuclear fusion of the sun's core takes place, and the fusion produces energy from the radiation region to the troposphere, and then to the photosphere. But the radiation region troposphere is with a very dense plasma, so such a density will make it difficult for photons to travel long distances because the dense plasma will constantly interact with photons, so although the speed of photons is the speed of light, in such a strong interaction, photons each time the propagation of just a few millimeters, so from the core to the photospheric layer, the light will probably take tens of thousands of years to experience the time.

But running out then, from the photosphere layer to the Earth only takes about 8 minutes. This is what we see light from the core to the photospheric layer, and then to the Earth a path, the photospheric layer above the chromosphere and coronal structure, but the photospheric layer releases the light is too strong, we generally can not see these two structures with the naked eye. So only when the light released by the photospheric layer is blocked, we can see this generally invisible sun.

This picture was taken during the total solar eclipse in 1999. The red and pink areas on the picture are the chromosphere of the Sun. The bright white area above the chromosphere is the sun's coronal structure, which exists like the sun's hair. The corona is the upper structure of the Sun's surface layer, which is filled with a great deal of the Sun's terrifying activity.

For example, this image is a coronal mass ejection taken with a coronagraph. The coronagraph is an approximation of an eclipse, using a disk to block the sun's photospheric layer since the observation of the sun's coronal structure, the size of the disk is generally designed to be larger than the visual view of the sun. The actual size of the visual is the size of the white circle in the center, so from this comparison, we can feel how horrible the coronal mass ejection of the Sun is.

The coronal mass ejection burst will form a solar storm, and such a burst if aimed at the Earth, then the Earth's magnetic field and electronic equipment will bring some impact.

This footage was taken of a massive coronal mass ejection back in 2017, and when the detector detected the outburst, the energetic particles released by the outburst also hit the detector, causing severe snowflakes in the image. There is also a very scary and stunning view of coronal rain in the coronal structure, a phenomenon in which plasma in the coronal structure, with reduced temperature, falls back to the surface of the Sun.

This image was taken in July 2012 under a coronal beauty, if the Earth is placed next to it, we can feel the horror of the size of the coronal rain, the formation of coronal rain is also caused by the strong magnetic field of the Sun, the role of the strong magnetic field so that the coronal structure of the plasma along the magnetic field lines of motion cooling and condensation, and thus fall back to the surface of the Sun, forming such an extremely stunning landscape. Such a landscape also allows the mysterious magnetic field to reveal itself, so that we can see the magnetic field line arrangement, well, this is a real shot of some solar images, this, everyone has any opinion?
