Solar corona viewed by Proba-3’s ASPIICS

The Sun’s inner corona appears greenish in this image taken on 23 May 2025 by the ASPIICS coronagraph aboard Proba-3, ESA’s formation-flying mission capable of creating artificial total solar eclipses in orbit.

This image, captured in the visible light spectrum, shows the solar corona similarly to how a human eye would see it during an eclipse through a green filter. The hair-like structures were revealed using a specialised image processing algorithm.

[Image description: This is an image of the Sun during an artificial solar eclipse. Against a black background, the Sun’s bright body is covered by a black disc, and light green hair-like tendrils extend from the black disc in all directions. Brighter green light peeks from behind the black disc’s edge, slowly fading towards the outer edges of the image.]
