Warren Ellis and Jerry Ordwa put Popeye in a comic with Diana Prince / Wonder Woman! He's a background character in a transit station in Gotham City. It's in Planetary/JLA: Terra Occulta, published in 2002. No idea if he fits in the story, or if there's some other reason the famous cartoon sailor man is in a superhero comic...

Asi comienza la mejor serie guionizada por Warren Ellis. #Planetary #WarrenEllis

Was only able to sharpen it up a tiny bit more. Bad seeing conditions that evening but I'm happy with it since I wasn't even planning on doing any planetary astronomy/astrophotography this year.

Astronomers & planetary geologists debate the definition of a planet. Small changes to the definition could have the side effect of reclassifying Earth🌎 & the Moon🌕 as a binary planet system. One step farther from being the center of the universe. #astronomy #planetary #geology

New paper by me out in #Geography Compass. “From globalisation to the #planetary: Towards a critical framework of planetary thinking in geography.

Attempts to ossify the planetary, with its decolonial, horizontalising, and anti-national thinking. It’s #OpenAccess too.

I'm a big fan of small telescopes and what can be done with them. What you've done with your Messier 16 photo is FANTASTIC.

I'm just not well set up for star photography, but I've done some #lunar and #planetary photography with small instruments.

The following photo of #jupiter was taken with an unmotorized #60mm refractor. The #yorick stacking software combined about 60 frames for the image. This was taken in 2010 when the SEB did one of its disappearing acts.

As one of the leading institutes in the field of #solarphysics and #planetary research, the @mpsgoettingen in #Goettingen is involved in numerous international #space missions.

The Solar System School @imprs_solar offers a research-oriented doctoral programme in #SolarSystem system science.

Said goodby to my stepchildren&fam: a #planetary #researchscientist (#Cassini), an #alpaca&miniature horse whisperer, a #musicaltheater #artist, an #appliedmathematics wiz who has developed a precise module for understanding how people are related to each other, the #teacher we all wish we'd had, and a young #history scholar and #athlete. Dissecting the #historical #referents of the #Major-General's" #Song_ was the best discussion I've had in years. I tried to keep up. Don't ask me to explain.
