NASA Astronomy Picture of the Day:

Planetary nebulae like Heckathorn-Fesen-Gull 1 (HFG1) and Abell 6 in the constellation Cassiopeia are remnants from the last phase of a medium sized star like our Sun. In spite of their shapes, planetary nebulae have nothing in common with actual planets. Located in the bottom left part of the featured photo, HFG1 was created by the binary star system V664 Cas, which consists of a white dwarf star and a red giant star. Both stars orbit their center of mass over about half an Earth day. Traveling with the entire nebula at a speed about 300 times faster than the fastest train on Earth, V664 Cas generates a bluish arc shaped shock wave. The wave interacts most strongly with the surrounding interstellar medium in the areas where the arc is brightest. After roughly 10,000 years, planetary nebulae become invisible due to a lack of ultraviolet light being emitted by the stars that create them. Displaying beautiful shapes and structures, planetary nebulae are highly desired objects for astrophotographers.

A reprint of a writing in 11/19/2020
I hope this will prompt me to write
more of beautiful things and less
of sadness. For viewing. Thank you

My emotions,
rage against me.
I will not pretend,
yet here I be.

Happiness and contentment,
I had many years.
Those feelings aren't present,
and these are my fears.

Forlorn is a condition,
I'm feeling right now.
Wanting to talk with someone,
but not knowing how.

I hesitate to show
interest in someone,
I do not wish to promote,
a false promise to anyone.
