They could be a collection of post-apocalyptic planets viewed from space. However these pieces of enchanting art were not made by humans but by natural phenomena. Science is beautiful.
The excellent Reddit page MicroPorn features close up microscopic images of materials. This collection of oxidised metal films were photographed using a microscope and an Amazon Fire phone by Reddit user Friz Face.
A stunning and vivid collection of bioart, these images should rightfully be hung on the wall in a gallery or in a lounge room, not languishing on a forgotten page on the internet! I wish I could share more with you about these pieces of art and Reddit user Friz Face but details were sketchy. See for yourself.
