    NGC 253

    NGC 253
    Also known as the Silver Coin Galaxy or the Sculptor Galaxy, a large, type Sc spiral galaxy, seen nearly edge-on. It is the brightest member of the Sculptor Group of galaxies in the constellation Sculptor and was discovered by Caroline Herschel on Sep. 23, 1783.

    NGC 253 is also classified as a starburst galaxy (the nearest one to Earth) because of the high rate of star formation and dense dust clouds in its nucleus. The energetic nuclear region glows brightly at X-ray and gamma-ray wavelengths.
