New supernova remnant sighted

A new optical supernova remnant has been found in the constellation Cygnus where 2 others—gamma Cygni and the Cynus Loop —were already known. This new optical supernova was discovered by 3 scientists observing at Kitt Peak National Observatory.

Theodore Gull (Lockheed Electronics Company), Robert Kirshner (University of Michigan), and Robert A. R. Parker (National Aeronautics and Space Administration) discovered the new supernova, a huge egg-shaped shell that measures about 220 light years in diameter. As it expands at a rate of more than 160,000 km/hour, the remnant is pushing a much larger shell of neutral hydrogen through the interstellar medium.
