NASA / ESA Hubble Space Telescope

A bubble seven light-years across, floating about 7,100 light-years away in Cassiopeia. The star at upper left of centre, forty-five times the mass of the Sun, blows a stellar wind of thousands of kilometres a second that pushes the surrounding gas into a soap-bubble shell. It was released in 2016 for Hubble's twenty-sixth anniversary.
