The image shows the smallest details of the outer corona of the Sun. The picture was taken on March 7, 2022 using
The image was taken using an extreme ultraviolet irradiance (EUI) meter. It shows the full disk of the Sun, the outer atmosphere and the corona.
In total, the photo contains over 83 million pixels in a 9148 x 9112 pixel grid. By comparison, that's ten times sharper than what a 4K TV screen can display.
The EUI takes pictures with very high spatial resolution, so at this close distance, you need a mosaic of 25 separate images to cover the entire Sun.
EUI uses 17 nanometer wavelength totake photos of the Sun, and also works in the extreme ultraviolet region of the electromagnetic spectrum. Thanks to this, it is possible to observe the upper layers of the Sun's atmosphere and the corona, the temperature of which is about 1 million °C.
