NGC 1491, also known as LBN 794, SH2-206 or Fossil Footprint Nebula, is an emission type bright nebula located about 9,800 light years away from Earth in the constellation of Perseus.[1] 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.[2][3]
