NGC 1019 is a barred spiral galaxy approximately 316 million light-years away from Earth in the constellation of Cetus.[2] It was discovered by French astronomer Édouard Stephan on December 1, 1880 with the 31" reflecting telescope at the Marseille Observatory.[4]
NGC 1019 is classified as Type I Seyfert galaxy.[2] Its nuclei is surrounded by tight rings or annuli of star formation,[5] and the rings contain compact, young star clusters.[6]
