A zoom into the southern constellation Vela to reveal the magnificent remnants of the Pencil Nebula. Zoom continues to Hubble's Advanced Camera for Surveys image of a small portion of the Pencil Nebula's wispy filamentary structures. The nebula's shape suggests that it is part of the supernova shock wave that recently encountered a region of dense gas. The Vela supernova remnant is 114 light-years across. The remnant is about 815 light-years away from our solar system.
