This galaxy was discovered by William Herschel on 20 September 1789 using his 18.7 inch reflector. He cataloged it as I 153 and noted: «Considerably bright, very large, extended, south proceeding, north following, above 15' length.» [463] Dreyer added it as NGC 908 to his «New General Catalogue» published in 1888.

Physical Properties

NGC 908 is a spiral galaxy in a distance of 65 million light-years and 75 000 light-years in size. It is a starburst galaxy that is undergoing a phase where many stars are born at a high rate. Clusters of young and massive stars can be seen in the spiral arms. The galaxy also presents uneven and thick spiral arms, indicating that it suffered a close encounter with another galaxy, even none is visible today. [640]
