NGC 253 is a normal spiral galaxy seen here almost sideways. It is the largest member of the Sculptor Group of Galaxies, the nearest group to our own Local Group of Galaxies. NGC 253 appears visually as one of the brightest spirals in the sky, and is easily visible in southern hemisphere with a good pair of binoculars. The galaxy is about 10 million light years distant. NGC 253 is considered a starburst galaxy because of high star formation rates and dense dust clouds in its nucleus. The energetic nuclear region is seen to glow in X-ray and gamma-ray light. This image is 4.5 hours of exposure taken in fair seeing on November 10 and 11, 2010.
