A supernova
An abstract yellow-orange star at the end of its life exploding and expelling matter at an unimaginable rate.
Supernovae are one of the most spectacular and awe-inspiring sights in astronomy. These colossal explosions can be seen from billions of miles away, and emit more light than an entire galaxy for a short period of time. Yet, they are usually taking place so far away that spotting one with bare eye would be nothing but seeing a star on the sky. However, they leave behind a cloud of matter that can turn into a nebula.
Supernovae are indeed one way for a star to die. The other ending to a star's life is to collapse under its own weight as it slowly runs out of fuel.
The photos and the story are (or will be) posted on my other social platforms, too.
