Sculptor Galaxy 소개
설명
The Sculptor Galaxy (NGC 253) is one of the brightest galaxies beyond the Local Group, located about 11.4 million light-years away in Sculptor. This nearly edge-on starburst galaxy spans 27 arcminutes and is the dominant member of the Sculptor Group.
관측 팁
A superb target, easily visible in binoculars as a bright, elongated streak. A 6-inch telescope shows mottled texture from dust lanes and star-forming regions. An 8-inch scope reveals stunning detail along its length. Best in autumn from locations with a good southern horizon.
역사
Discovered by Caroline Herschel on September 23, 1783. It is one of her most famous discoveries. The galaxy's strong infrared emission revealed its starburst nature in the 1970s.
재미있는 사실
The Sculptor Galaxy is producing new stars at a rate roughly 10 times higher than the Milky Way, qualifying it as a starburst galaxy. Its central region contains a superwind of hot gas driven out by the intense star formation.
