🧵 10 May 1900: astronomer Cecilia Payne-Gaposchkin, an example of pure love for #science, was born. "No idea should be suppressed. … And it applies to ideas that look like nonsense. We must not forget that some of the best ideas seemed like nonsense at first." 🔭 🧪 #histsci #WomenInStem #astronomy

🧵1/5 Ever get that weirdly satisfying feeling when something finally goes way past its original plan? Well, #NewHorizons just did exactly that. After 20+ years since launch, it's now farther from Pluto than it was back in 2006. Really wild when you think about it.🔭 🧪 ⚛️ #Space

🧵1/5 For 170 years we thought there was a large inclined ring of young stars around the Sun.🔭 A new study using Gaia data shows instead that it doesn’t exist: Gould’s Belt is just a temporary alignment of a few star clusters.🧪⚛️ No ring, just a 3D asterism. arxiv.org/abs/2604.13225 #galactic

Elon hates NASA because its existence and success counters the myth that we need billionaires or a profit motivation to do cool things in space. Anyways, nationalize spacex.

IT'S APPOMATTOX DAY! Use that word, as I did, holding it up, on a busy streetcorner Only some MAGAPutinists get it. But their eyes widen in realization and fear. Good. We blue Americans are made of no lesser stuff than the blue heroes of Gettysburg.

I sat and I thought till my thinker was sore: If Venus is like Earth with mantle and core and similar size, yet in life is so poor, maybe, just maybe, “Earthlike” means something more…

If you aren’t following Martin Longman, you need to. I’ve appreciated his brilliant political insights for two decades. How Democrats can win rural voters, etc. I feel for him and other thinkers, though. What brilliant thing is there to say? Everything is just maximally cruel and stupid.

El día a día en Artemis II Artemis II, la primera misión tripulada desde el programa Apolo, llevará a cuatro astronautas alrededor de la Luna, sin aterrizar. Con un detallado calendario de actividades, la misión evaluará el rendimiento de la nave Orion y su tecnología vital. Este vuelo es crucial…

I was born 1970. I have 50+ years of memories. None include humans leaving low-Earth orbit. But I remember too well the 1986 Challenger launch on the TVs in school. I find I cannot even process the launch I just saw. It’s too surreal. Any other GenXers feel the same?

Yep. Magical thinking, just like with covid and everything else.

Spain invested heavily in clean energy over the last 6 years. Now, as gas prices rise, Spain has some of the lowest electricity costs on the continent. In August 2025, Spain used zero coal — just 10 years ago it powered 25% of the country. This is what energy independence actually looks like. 🌎

When I moved here in 2003, the average number of 110+ days per year was “12-18”. In the last 7 years we’ve had two with > 50. Phoenix warmed as the urban heat island expanded but that stalled in the 80s/90s. The warming since then is all climate change. We need every solution on the table now.

Star formation was a mistake 😏🔭 (by @xkcd.com)

The loud boom heard in Cleveland and the light seen across the Midwest and Mid-Atlantic... it was a meteor! GOES-19's geostationary lightning mapper picked up the brief flash of light.

TIL that funk legend Bootsy Collins not only made way more music I love than I realized, he also created Funk University in 2010 to teach bass, history of funk, etc. Unfortunately I can’t find current information on it and I worry it’s now defunked.

Yes, we talked to a geologist who curls about the very special geology of curling's stones, please enjoy

I agree, but by any definition my birth year (1970) is pretty much peak Gen X. And in true Gen X fashion, I think we, as a generation, kinda suck.
