Surprised Eel Historian, PhD @greenleejw.bsky.social · 02/01/2026
In January 1421 a small fleet of Dutch ships arrived in London. And did they bring the eels? Oh yeah. One ship, belonging to Gerbrand Heykysson, unloaded 400 large eels, 2,700 medium eels, 23,00 small eels, & 6 barrels of salted eels. Also a small sack of feathers. 🗃️🧪
Meme. Photograph of an American eel underwater, peeking out from some rocks. We'll call him Whumblorn. He looks skeptical about life in general, and about you specifically. His red eye is rimmed in blue, and he seems to be staring right through your chest, like he wants to read the funny thing on the back of your shirt by looking through you.

Whumblorn's underneath is a beautiful silver color, and his top is a dull black. Don't judge, though. This seems natural for him, and he is perhaps wondering why your top and bottom are the same colors. You don't get to judge the eels, but they sure as biscuits will judge you. And hard. They didn't swim here from the deep Sargasso to just let you slide by. Whumblorn is here to make you a better person. And that starts with judgement.

His eye isn't reading your shirt. It's reading your soul. And he's not at all sure that you're ready for what's coming next.

Meme text reads:
"Bro.
Eels don't have feathers."

Confused, Scrooge stepped onto the ice. He looked around, wracking his brain but for nought. He turned to the spirit, who was idly twirling a broom. "Sir, I have no memory of this place. Why have you brought me here?" The phantom shrugged and replied "I just really like curling is all".

I am so happy that Walrus from Space is getting some media attention. It's the only citizen scientist project I've ever participated in as a classifier, and it gave me a real sense that I could help at a time of David Attemborough-induced walrus trauma on my part...

As quirky as the project title is, this is actually a super neat program! Walrus depend on beaches for their haul-outs, which allow them to rest and to breed. As sea ice retreats, they can only haul-out on land. Walrus from Space uses crowdsourced power to identify new haul-out locations!

Marvelous new image of interstellar Comet 3I/ATLAS, taken by photographer Satoru Murata before dawn this morning. On the right you can also see galaxy NGC 4691. There should be a lot more pictures coming in soon. 🧪🔭 www.facebook.com/groups/22700...
Interstellar comet ATLAS seen early this morning as a thin crescent moon passed immediately next to it. Still was able to capture three separate jets of ionic tail, and an anti tail? Or the dust tail? The comet was also passing by the galaxy NGC4691, which really gave the impression of the object being from another world.

Photograph of a red sprite. It has three vertical columns that branch out towards the top and and in the middle. The thing looks a bit like someone's crude attempts to paint lines with a can of spray paint. The color is a very vibrant red against a blueish nightsky with many stars.

What is common knowledge in your field, but shocks outsiders? The precision achieved in timing the millisecond pulsar PSR J1909-3744 is ~100 nanoseconds over 15 years. That allows us to calc changes in relative Pulsar-Earth distance to an accuracy of ~30m. 📸 Liu et al. (noise subtracted plot)
two plots stacked on top of each other. They show time on the x-axis and timing residuals on the y-axis. The top plot has a slight wave in it, while the bottom plot is remarkably flat after noise has been subtracted. The annotated weighted rms is 103 nanoseconds.
