The Hubble Telescope -Orion Nebula Mosaic Wall Poster

A mosaic of fifteen seperate fields covering an area of sky about five percent of the area covered by the full moon, this picture is one of the largest ever assembled from individual images taken by the Hubble Space Telescope. It reveals a churning star factory set within a maelstrom of flowing, luminescent gas. This nebula is a vast laboratory for studying the processes that gave birth to our own Sun and solar system 4.5 billion years ago. The mosaic reveals at least 153 glowing protoplanetary disks (first discovered with the Hubble in 1992 and dubbed "proplyds") which are believed to be embryonic solar systems that will eventually form planets. The Orion Nebula is located 1,500 light-years away along our spiral arm of the Milky Way, in the middle of the sword region of the constellation Orion the Hunter, which dominates the early winter evening sky at northern latitudes.
