Solar Orbiter spots ‘campfires’ on the Sun

A high-resolution image from the Extreme Ultraviolet Imager (EUI) on ESA’s Solar Orbiter spacecraft, taken with the HRI_EUV telescope on 30 May 2020. These images revealed ubiquitous features of the solar surface, called ‘campfires’.

On 30 May, Solar Orbiter was roughly halfway between the Earth and the Sun, meaning that it was closer to the Sun than any other solar telescope has ever been before.

Solar Orbiter is a space mission of international collaboration between ESA and NASA.
