Fireworks Galaxy 소개

설명

The Fireworks Galaxy (NGC 6946) is a face-on spiral galaxy straddling the border of Cepheus and Cygnus, about 25 million light-years away. It is notable for its prolific supernova production.

관측 팁

Visible as a round, diffuse glow in a 4-inch telescope. Larger scopes reveal a brighter nucleus with faint spiral arm hints. Low surface brightness means dark skies are important. Best in summer and autumn evenings.

역사

Discovered by William Herschel on September 9, 1798. Ten supernovae have been observed in this galaxy since 1917, more than in any other known galaxy.

재미있는 사실

With 10 observed supernovae (1917A, 1939C, 1948B, 1968D, 1969P, 1980K, 2002hh, 2004et, 2008S, 2017eaw), NGC 6946 has earned its "Fireworks" nickname. The average galaxy produces only 1-2 supernovae per century.
