A new image from the Hubble Space Telescope shows Jonckheere 900 or J 900, a planetary nebula -- glowing shells of ionized gas pushed out by a dying star. Discovered in the early 1900s by astronomer Robert Jonckheere, the dusty nebula is small but fairly bright, with a relatively evenly spread central region surrounded by soft wispy edges.
