I think that’s a stellar wind bubble, cool find!
I found the same exact thing on google

It’s actually a planetary nebula. The central star has run out of fuel and released its outer layers (causing the nebula) and become a white dwarf.

I just searched Google for planetary nebula and the results are very beautiful

Why is it not in the star clusters and planetary nebula catalog?

I think we plot just GCs & PNe that are in the NGC catalog

*I am sure that GCs and PNe needs an update. I may provide a .fits file when I completed.

It’s an open-source project – feel free to send a Pull Request!
