Description

NGC 1491 (also known as the Fossil Footprint, LBN 704 or Sh2-206) is a bright nebula discovered by William Herschel in 1790, in the constellation of Perseus. It is glowing deep red because the hydrogen gas in the nebula is energized by hot, massive stars embedded within. These stars emit copious amounts of ultraviolet (UV) light that causes the gas to glow.
