View Full Version : Discussion: Hubble Reveals the Pencil Nebula

2003-Jul-08, 10:04 PM
SUMMARY: The Hubble Space Telescope has taken a new image of the Pencil Nebula, officially known as NGC 2736, which is part of the huge Vela supernova remnant located 815 light-years away. The nebula's luminous appearance comes from dense gas regions which have been struck by the supernova's shock wave and heated up. Astronomers estimate that the supernova went off 11,000 years ago; although, no historical records of the explosion have ever been found.
