NGC 1491, also known as the Fossil Footprint Nebula, is an emission nebula located about 10,700 light-years away in the constellation Perseus. This bright nebula is illuminated by a hot, young star at its center, which emits intense ultraviolet radiation that ionizes the surrounding hydrogen gas, causing it to glow with a reddish-pink hue characteristic of hydrogen-alpha emission. NGC 1491 also features complex structures sculpted by the star’s powerful stellar winds, creating intriguing ridges, cavities, and wispy filaments in the gas and dust. The nebula is a site of active star formation, and its structure is continually shaped and eroded by the energetic young stars within it. Observations of NGC 1491 provide astronomers with insights into how massive stars interact with and alter their surrounding environments, contributing to our understanding of stellar life cycles and the evolution of nebulae in the galaxy.
