The total solar eclipse seen from Casper, Wyoming (US), by a team of ESA astronomers.

The image shows part of the Sun’s chromosphere, which sits just above the Sun’s visible surface, and appears red during a total solar eclipse. It also captures the last beads of light glinting through gaps in the rugged lunar topography.
