2020 September 28 - Filaments of the Cygnus Loop
Channel: APOD Podcast
Date: 2020-09-28

In today's image, we see a part of the supernova remnant known as the Cygnus Loop. This is the remnant of a star which was seen to explode on Earth 20,000 years ago. This is a part of the shock wave expelling material out into the interstellar medium which has been enriched with heavier elements (Anything other than hydrogen or helium.)
