“Galactic Cirrus: Mandel Wilson 9” is copyrighted by Gabriel Rodrigues Santos. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteThese faint, wispy structures are cosmic dust clouds, sometimes called galactic cirrus. They float about 300 light-years above the Milky Way's plane. These clouds reflect the combined light of distant stars and also emit a subtle reddish glow from interstellar hydrogen, tracing large regions of the sky.
