Hubble and Webb Image Galaxies’ Lost Stars

Deep images of galaxy clusters reveals the light of wandering stars. What set these stars free from their hosts?

Illustration of a planet and its star on a black background. The planet is large, in the foreground at the centre, and the star is smaller, in the background and also at the centre. The planet is rocky. The top quarter of the planet (the side facing the star) is lit, while the rest is in shadow. The star is bright yellowish-white, with no clear features.
