Happy Solstice 2020!

The evening began with a beautiful sunset:

...though pretty clouds meant Jupiter and Saturn's closest dance was a little fuzzy:

While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2,400 light-years away. The name of the supernova remnant comes from its position in the northern constellation of Cygnus (the Swan), where it covers an area 36 times larger than the full Moon.
