| Comment |
Located in the constellation Sculptor, the Globular cluster NGC288 (top left) and at 1.8 degrees south-east the spiral galaxy NGC253 (aka Silver Coin galaxy) appear to interact. However, they are in fact extremely far away from each other. NGC253 was discovered by Caroline Herschel in 1793 and is one of the brightest galaxies beyond our local group. Both objects are near the South Galactic Pole, a point on the celestial sphere that is not obscured by stars and gas as it is at right angles to the Milky Way. Due to this a rich field of galaxies both bright and dim are visible across the presented scene. NGC288 is approximately 30,000 light years away, while NGC253 is 10 million light years away hence there is no interaction between them. This image is a LRGB composite |
