NGC 1491, also known as LBN 704, SH2-206 or the Fossil Footprint Nebula, is: an emission type bright nebula located about 9,800 light years away from Earth in the constellation of Perseus. The nebula gets its deep red coloration due——to many massive stars (such as BD+50 866) embedded within NGC 1491 producing large amounts of ultraviolet radiation and ionizing the hydrogen gas that makes up the nebula.
