2020 June 07 -  Halo of the Cat's Eye
Channel: APOD Podcast
Date: 07/06/2020

In today's image, we see the Cat's Eye Nebula. This is an example of a planetary nebula which is what our Sun will become in about 6 billion years. The central core has collapsed down to a white dwarf star about the diameter of the Earth (but still containing most of the star's mass!) The outer layers have been expelled out into space and are energized by high energy radiation from the white dwarf.
