✨ What you see in this image is the aftermath of a massive stellar explosion. The progenitor star is estimated to have been about 20 times more massive than the Sun. This supernova occurred thousands of years ago, and estimates suggest it may have appeared brighter than Venus in Earth's sky. However, it took place before the beginning of recorded history, so no known human record of the event exists.
💫 Even today, we can still observe the resulting shock wave expanding through space at speeds of around 100 km/s, creating the delicate glowing filaments that make the Veil Nebula one of the most spectacular supernova remnants in the night sky.
📍 Distance: Approximately 2,400 light-years from Earth.
🌀 True size: Part of a stellar remnant spanning more than 100 light-years across.
📐 Apparent size: Together with the rest of the Veil Nebula complex, it covers an area about six times the diameter of the Full Moon.
