This video shows how the planetary nebula Hen 3-1357 (aka the Stingray Nebula) has faded since the mid 1990s. The nebula is first seen as photographed by the Hubble Space Telescope in 1996, with filaments and tendrils of gas glowing bright blue at its center. Then it transitions to Hubble’s 2016 image, which shows a much dimmer nebula lacking in the pronounced wavy edges.
