Supernovae are stars that explode and destroy in their final days.
As a result, a lot of debris remains.
The image shows faded filaments that are part of the remnants of a large supernova, the Cygnus Loop.
The visual part of the signus loop is known as the Veil Nebula or the Cirrus Nebula or Filamentary Nebula.
Many of the components found within it have specific names and identifiers. The main parts are “Western Veil” or “Witch’s Broom”, “Eastern Veil” and “Pickering Triangle”.
It is located about 1,500 light-years from Earth. These filaments are the remains of a star that exploded 5,000 to 10,000 years ago. The image was created by observation using oxygen (blue), sulfur (green), and hydrogen-alpha (orange) filters.
