These images of Jupiter, Saturn, Uranus, and Neptune were all acquired by NASA. I placed them on this polyhedron, and created this rotating .gif, using Stella 4d, which you can try for free at this website.

The Galilean Moons of Jupiter on a Rotating Rhombic Dodecahedron
These images of Ganymede, Io, Callisto, and Europa were all acquired by NASA. I placed them on this polyhedron, and created this rotating .gif, using Stella 4d, which you can try for free at this website.
An Astronomical Dodecahedron
NASA’s Artemis I spacecraft snapped this picture of the Earth moving out from behind the far side of the Moon. I put it on this rotating dodecahedron using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.

Happy Moon Day!
To celebrate Moon Day — the anniversary of the first Moon landing — this year, I made a rhombic triacontahedron with colored images of the Moon on each face. I got the image of the Moon from its Wikipedia page, and made this polyhedral image using Stella 4d, a program you can try for free right here.

A Brief Visit to the Eighth Planet, Assisted by Tonight’s Crazy Arkansas Weather
The sky bursting full of rapid and illuminated clouds, rushing bright blue against an indigo background, made me feel I was looking up at the planet Neptune, stretching from one horizon to the other. I went inside, to get my phone, to snap a picture, but, when I got back out, the eighth planet above had been replaced — by a stormy-but-normal third-planet sky. I came back inside with no images, except in memory.

I’m Walking on an Active Volcano at Yellowstone National Park
At the time my wife took this picture, I did not yet realize that we were walking around on an active volcano when we recently visited Yellowstone National Park. The outgassing behind me, which I had just walked through, should have clued me in, since it had a strong smell of hydrogen sulfide mixed with hydrochloric and sulfuric acids. At a gift shop, I found a book by Greg Briening called Super Volcano: The Ticking Time Bomb Beneath Yellowstone National Park. It explains the science of Yellowstone, and makes a strong case that the volcano that created Yellowstone will blow up again, possibly soon, with cataclysmic consequences worldwide.
These vandalized goggles were found in my science lab at school yesterday. When I tried them on, they literally had me seeing red.
