Close-up portraits of the Sun are visually stunning. ESA and NASA are the two astronomical bodies that have managed to take close-up pictures of the Sun.
Esa along with NASA showcased amazing pictures of the Sun that they took.
Taking pictures of the center of the solar system through a spacecraft with high resolution results in the form of a corona, full disk, and outer atmosphere.

Close-up Portraits of the Sun
Launching from ESA on Saturday (2/4/2022), they managed to take a close-up image of the Sun through the EUI or Extreme Ultraviolet Imager together with the Spectral Imaging of the Coronal Environment (SPICE) instrument.
The image SPICE took represents the first full Sun portrait of its kind in 50 years. So far this picture is the best.
SPICE takes pictures of the Sun with the help of the Lyman-beta wavelength of ultraviolet light that hydrogen gas emits. This image was captured by the Solar Orbiter when it was at a distance of approximately 75 million kilometers from the Sun.
Solar Orbiter itself is a space mission as evidence of international cooperation between ESA and NASA.

High Quality Image Results
In addition to SPICE, the EUI high-resolution telescope also takes close-up portraits of the Sun. The telescope produces a very high spatial resolution.
At such close range, it would take a mosaic of 25 individual images to cover the entire Sun. They took the mosaic pictures one by one for more than four hours.
In total, the final close-up portrait of the Sun contains more than 83 million pixels in a 9148 x 9112 pixel grid. In comparison, the resulting picture has a resolution that is ten times better than a 4K TV.
EUI took a snapshot of the Sun, at which time the wavelength reached 17 nanometers in the extreme ultraviolet surround of the electromagnetic spectrum. As a result, EUI succeeded in revealing the hottest upper atmosphere of the Sun, namely the corona.
The surface has a temperature of up to one million degrees Celsius, while the surface of the other Sun is only about 5,000 degrees Celsius.
Then at 2 o’clock (image from Earth for scale) and at the edge of the Sun at 8 o’clock, dark filaments can be seen protruding from the surface.
The bulge tends to erupt, throwing large amounts of corona gas into space and creating ‘antarctic weather’.
In a series of close-up portraits of the Sun via SPICE, several colors can be seen that show the temperature level of parts of the Sun.

The color is purple with hydrogen gas at 10,000 degrees Celsius and blue turning into carbon at 32,000 degrees Celsius.
While the green color which is oxygen is at 32,000 Celsius, and yellow to neon at 630,000 degrees Celsius.
This close-up portrait of the Sun by the Solar Orbiter was taken on March 7, 2022 as it crosses the line of the Sun and Earth. On March 26, 2022, the Solar Orbiter achieved another mission milestone, namely inside Mercury’s orbit to record data on the solar wind. (R10/HR-Online)
