Meanwhile,
You have never seen sun:
Have you ever tried to take a photo of the sun? Furthermore, Or even watch it directly? Furthermore, Without suitable protective material, its light burns the retina in a few moments. In addition, So imagine now traveling 75 million kilometers to get closer to the sun. Therefore, You have doubled Venus on the way. In addition, You are close to Mercury.
The sun’s rays are crazy. Similarly, Despite everything, for more than 4 hours, you chain the shots to make the most beautiful possible image of the sun. Similarly, All this, the European probe Solar Orbiter has just done so. On March 9, she captured 200 images of the star of the day. Only 70 million kilometers from its surface.
The final rendering is just crazy. An image of 12,544 x 12,544 pixels with the sun, majestically enthroned in the center. In addition you have never seen sun to the obvious beauty of such a cliché. this image allows us to learn a little more about the center of our solar system.
Solar and plasma tasks – You have never seen sun
On the bottom of the image, you can notably see a “black line”. It is actually a particular plasma, denser than the others. It owes its color to its temperature, relatively low (10,000 ° C all the same). This particular material absorbs the light emitted below.
If we had had this same image but on the side, we would have seen prominence. They spread over several thousand kilometers, for days or even months. Just above this line, on the right sun flan, we can observe “sundas”.
These very active regions are responsible for eruptions and other corolarous masses ejections. When they go straight to earth, they create boreal aurora. It is therefore thanks to them that 75 million kilometers further. at the you have never seen sun borders of the Arctic Circle, thousands of tourists benefit from a colorful spectacle, literally.
An image… invisible
If this shot is magnificent. allowing to discover the smallest details of the sun, it is actually, that an immense assembly. Indeed, ESA used a very special wavelength to observe the sun with its probe: 17.4 nanometers. At this frequency, we are talking about extreme ultraviolet radiation. They are invisible to the naked eye.
In other words. if you were in place of Solar Orbiter on March 9, you would not have seen anything of all this. The image taken by the probe is imperceptible for our human eyes. We are only able to see the light between 495 and 555 nanometers. Within this very small interval, all the nuances of all colors are visible. The rest of the universe, going below or above these values, are not visible to us.
You can you have never seen sun learn more and observe the sun in high definition from the ESA site here.
