"THE SCULPTOR GALAXY"
- Deepsky 2860mm LRGB
- Area Constellation Sculptor
The Sculptor Galaxy, also known as Silver Coin or Silver Dollar Galaxy (aNGC 253), is an active Hubble-type SBc barred spiral galaxy with a high star formation rate in the constellation of Sculptor in the southern sky and the third brightest galaxy outside the Local Group after Centaurus A and Messier 81. At a distance of 11 million light years, the Sculptor Galaxy is one of the nearest galaxies outside the Local Group and is similar in size and shape to the Milky Way, with a diameter of around 100,000 light years.
However, the position of this galaxy in the sky is too far south to be easily observable in Central Europe, so it is not included in the Messier catalog despite its brightness. The galaxy was discovered by the German astronomer Caroline Herschel on September 23, 1783 and is the closest starburst galaxy.
