IC 443 – JellyFish Nebula

November 3, 20191 min read

In a period between 3000 and 30000 years ago, a star exploded in supernova throwing its surface gases at a huge distance. What we see today is what is left of this explosion, which now covers an area of about 70 light years, at 5000 light years from us.
