NGC253
Sculptor Galaxy
The
Sculptor Galaxy, named so because it is located in the Sculptor
constellation, is also called the Silver Dollar Galaxy due to its
appearance. It is over 11 million light-years from Earth and measures
90,000 light-years across. Because of its brightness it is a well
studied galaxy, and is in the middle of a "starburst" period of star
formation. Note the numerous and complex dust lanes. North
is at the top.
