VIVA – European Space Agency (European Space Agency /THIS) and the National Aeronautics and Space Administration/NASA) successfully photographed Sun with the highest resolution of full disk, outer atmosphere and corona ever taken from the Extreme Ultraviolet Imager (EUI).
Citing site Universe TodaySunday, April 3, 2022, another image, taken by the Spectral Imaging of the Coronal Environment (SPICE) instrument represents the first full Sun image of its kind in 50 years, and by far the best, taken at the Lyman-beta wavelength of ultraviolet rays which is emitted by hydrogen gas.
The image was taken when the Solar Orbiter was at a distance of about 75 million kilometers, half way between our world and its parent star. Solar Orbiter itself is a space mission of international cooperation between ESA and NASA.
The EUI high-resolution telescope takes images with such a high spatial resolution that at such close distances a mosaic of 25 individual images is required to cover the entire Sun.
Images were taken one after another, the full image taken over four hours as each mosaic took about 10 minutes, including time for the spacecraft to point from one segment to the next.
In total, the final image contains more than 83 million pixels in a 9148 x 9112 pixel grid. In comparison, this image has ten times better resolution than a 4K TV screen can display.
