The European Space Agency, working in collaboration with NASA, has posted a high-resolution image of the Sun as seen by Solar Orbiter, taken on 7 March.

The image is a mosaic of 25 individual images captured in extreme ultraviolet light from a distance of roughly 75 million kilometres by the high resolution telescope of the Extreme Ultraviolet Imager (EUI) instrument. Taken at a wavelength of 17 nanometers, it reveals the Sun’s upper atmosphere, the corona, which has a temperature of around a million degrees Celsius. In total, the final image contains more than 83 million pixels in a 9148 x 9112 pixel grid, making it the highest resolution image of the Sun’s full disc and outer atmosphere, the corona, ever taken. An image of Earth is also included for scale, at the 2 o’clock position.
