Veil Nebula: Wisps of an Ancient Supernova. /Courtesy of Abdullah Alharbi

About 7,000 years ago, a supernova explosion caused the star to disappear, leaving behind the Veil Nebula. The expanding cloud at that time is believed to have been as bright as a crescent moon. The Veil Nebula itself is physically immense, occupying a sky area over five times larger than a full moon, despite being located about 1,400 light-years away from Earth (1 light-year is the distance light travels in one year, approximately 9.46 trillion kilometers). This photo was taken in mid-2024 in Kuwait, capturing the red light emitted from hydrogen and the blue light emitted from oxygen.
