A Primordial Quasar - The nearest quasars are now known to be supermassive black holes in the centers of galaxies. Gas and dust that falls toward a quasar glows brightly, sometimes outglowing the entire home galaxy. The quasars that formed in the first billion years of the universe are more mysterious, though, with even the nature of the surrounding gas still unknown.

NGC 7023, also called the Iris Nebula for its floral appearance. The cosmic flower is actually what's known as a reflection nebula. The interstellar cloud of dust and gas glows not because its material is being heated, but because it's reflecting light from nearby stars.

XZ Tauri, a newborn star spraying out gas into its surroundings and lighting up a nearby cloud of dust (star is just down and to the right of centre, the spikes coming off it are an image artefact).

3/02/2011: NGC 1499, The California Nebula. Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way's Orion Arm, only about 1,500 light-years from the California Nebula. The classic emission nebula is around 100 light-years long.

NGC 2237 Inside the nebula lies an open cluster of bright young stars designated NGC 2244. These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas. Ultraviolet light from the hot cluster stars causes the surrounding nebula to glow. The Rosette Nebula spans about 100 light-years across, lies about 5000 light-years away, and can be seen with a small telescope
