2022 December 07 - NGC 7293 The Helix Nebula

December 07, 2022

In today's image, we see the planetary nebula known as the Helix Nebula and also known by the catalog designation of NGC 7293. This is the end state of a star much like our own Sun. When it runs out of fuel, the core collapses down to form a white dwarf star about the size of Earth and the outer layers expand, eventually becoming detached and giving rise to the nebula we see here today.
