Before the DeLorean, there was this vintage time machine. Consequently, I am posting this three days after tomorrow. I had fun lighting this selfie! It's more fun than AI-generated images. Photographed while Tim Little and I were teaching a night photography workshop at Nelson Ghost Town in Nevada.

Explanation:
What is creating the strange texture of IC 418? Dubbed the Spirograph Nebula for its resemblance to drawings from a cyclical drawing tool, planetary nebula IC 418 shows patterns that are not well understood. Perhaps they are related to chaotic winds from the variable central star, which changes brightness unpredictably in just a few hours. By contrast, evidence indicates that only a few million years ago, IC 418 was probably a well-understood star similar to our Sun. Only a few thousand years ago, IC 418 was probably a common red giant star. Since running out of nuclear fuel, though, the outer envelope has begun expanding outward leaving a hot remnant core destined to become a white-dwarf star, visible in the image center. The light from the central core excites surrounding atoms in the nebula causing them to glow. IC 418 lies about 2000 light-years away and spans 0.3 light-years across. This false-color image taken from the Hubble Space Telescope reveals the unusual details.

#UMPlus - NGC 6106 by Jerry Yesavage

universomagico.net/2025/04/ngc

This image by astronomer Jerome Yesavage shows the spiral galaxy NGC 6106, visible in the direction of the constellation of Hercules, located at a distance of about 67 million light-years from the Milky Way. NGC 6106 is notable for having hosted two recent supernovae, in 2020 and 2024, called AT 2020kog and.....

Earthshine nights are coming up on April 30 and May 1! These are the best nights to see the dark portion of a crescent Moon because the Sun’s light reflects off Earth and illuminates the Moon. They occur a few days before and after a New Moon.
