NGC 1894 is an open star cluster located in the constellation Columba. It was discovered by the astronomer John Herschel in 1834 and is situated approximately 20,000 light-years away from Earth. The cluster contains several bright stars and is estimated to be around 100 million years old. The stars in NGC 1894 are loosely bound by gravity, allowing them to spread out over a larger area compared to globular clusters. This cluster is of interest to astronomers studying stellar evolution and the dynamics of star formation in open clusters.
