On the 5th day of fossils, my true love gave to me... 5 GOLD TRILOBITES! Beecher's Bed is a special Ordovician site in New York that preserves trilobite soft tissue with pyrite replacement. Legs, antenna and even trilobite eggs are found here. 1/x #12DaysofFossils

On the 1st day of fossils, my true love gave to me... A Clarkeocrinus troosti. I only have 1 in my collection. Despite my online handle, it is not named after me. This Devonian crinoid was named after the first New York State Museum Director, John M. Clarke. #12DaysofFossils

Closing out my year with a journal editor shocker 🧵 Checking new manuscripts today I reviewed a paper attributing 2 papers to me I did not write. A daft thing for an author to do of course. But intrigued I web searched up one of the titles and that's when it got real weird...

I wanted to do a quick thread about this paper led by a great postdoc here at JPL, Flavio Petricca, which suggests that Titan may not have a global ocean after all. www.nasa.gov/solar-system...

Some plants generate their own heat to attract warmth-seeking pollinators. Heat-guided pollination may be an ancient trick that predates scent & color as a way to help plants reproduce. Amazing what you see when you look at the world in thermal vision. 🧪 news.harvard.edu/gazette/stor...

55 years ago this morning, BANEBERRY—a 10-kiloton, weapons-related, underground nuclear test 912 feet beneath the Nevada Test Site—accidentally vented, releasing 6.7 million curies of radioactive debris, including 80,000 curies of iodine-131, the second largest venting in US history. (THREAD)

I was pleased to play a small role in this study of a jet from the protostar SVS13. In an elegant analysis led by Guillermo Blázquez-Calero, Mayra Osorio, & Guillem Anglada of IAA, we detect with ALMA wakes in the outflowing gas due to fluctuations in the jet. www.almaobservatory.org/en/press-rel...

New results from the International Gemini Observatory 🔭 on interstellar comet 3I/ATLAS, in which it continues to do fun cometary things! The new spectrum confirms 3I/ATLAS is actively emitting CN, C3, and C2 gases, plus a visible dust fan. www.astronomerstelegram.org?read=17503

A new census of OB associations with Gaia! In this study, we took advantage of my OB stars map to find new OB associations within 1 kpc. The goal was to create a useful reference catalogue for this era, and to trace the star formation and structure of the local Milky Way. #stellarastro #galactic

Our new study provides rare causal evidence about NYC’s speed camera program. We find large reductions in collisions (30%) and injuries (16%) near intersections with cameras. www.pnas.org/doi/abs/10.1... @astagoff.bsky.social ky.social @brendenbeck.bsky.social nbeck.bsky.social 🧪

Y'all the latest episode of the #Kilauea #eruption just went CRAZY. It looks like pressure built up enough to explode out the ground around the two existing vents (first few seconds), leading to a massive surge in lava fountaining.🌋🤯 USGS Live stream: www.youtube.com/watch?v=fiyt...

NASA has completed the construction of #NASARoman! Last month, technicians joined the inner and outer portions of the observatory in Maryland. After final testing, Roman will move to the launch site at the Kennedy Space Center for launch preparations in summer 2026: https://go.nasa.gov/48EqnE8 🔭 🧪

You've probably heard about how the rapidly increasing numbers of satellites are affecting #astronomy. A new paper in @nature.com looks at the possible future for space-based telescopes — and finds 96% of some images could be impacted. 🧪🔭🛰️ By @jennaahart.bsky.social www.nature.com/articles/d41...

I have exceeded my limit and I just can’t anymore today. Even so, I wanted to share this pretty image of NGC 281, the Pacman Nebula. It’s about 9000 light years away in the direction of Cassiopeia. 5.3 hrs, #Seestar S50 from N. Atlanta suburbs 🔭 🧪 Siril, GraXpert, Starnet, GIMP

It's time, folks! This was huge on Twitter back in the day and we need to keep it going on Bluesky. The annual #TreeByBike haul begins and your photos will be an inspiration to everyone. 🎄🚲

An excellent and very clear piece on LLM's and thinking. See also Farrell et al. in Science, our piece making the point about LLM's as a form of communication rather than cognition. alisongopnik.com/Papers_Aliso...

In the past year we've had a series of papers with results that've shocked #climate scientists - the globe is heating #FasterThanExpected & we don't fully know why The public discourse is not keeping up. Here's a series of 5 new studies that climate hawks & journos need to have on their radar 🧵

This is an incredible image of comet 3I/ATLAS, taken by Satoru Murata ICQ Comet Observations group on 16 November 2025 from western New Mexico. Structure within the major dust tail from the comet is clearly visible, together with two smaller jets trailing the nucleus and maybe even an anti-tail.

The Pacman Nebula NGC 281 in Cassiopeia had been on my wish list for several years, and now, over the course of 4 nights in September & October, I finally got it. Visually not an easy object due to light pollution, but really fun to photograph (tech. details in image) 🔭 @kat-astro-bot.bsky.social

I take on average 10,000 stills and a half hour of video every week. Most I'll never think about again. This I'll hold onto until I grow old. 4 hours ago. Zero edits. No recoloring. No cropping. Nothing. Just straight up reality. 🦑

Because of the assassination, Major Kong’s (Slim Pickens) reference to Dallas in the scene where he carefully itemizes the contents of the crew’s survival kits was dubbed in post-production to Vegas. But “Dallas” can still be heard on the French-dubbed audio track of the version released in France.

The Boogeyman Nebula 🌌 Here's a fun astrophotography target to try with your telescope this season - but be warned, this one takes TIME! LDN 1622 is a dark nebula in the constellation Orion that resembles 'a dark figure with a head and arms' (I kinda see it!) This is 10 hours! #astrophotography

A stellar nursery at its finest! 🔭 This is LHA120-N159 region in the LMC as seen by the JWST one year ago. It is home to MANY new born stars and many more to come! I was in awe with how beautiful this region is while I was processing these data earlier this morning! HD: flic.kr/p/2rGG32u

(1/n) Image thread about the LHA 120-N 159 (or just N159) region with #JWST NIRCam. Here the filters F300M (blue), F335M (red) and F460M (green) 🔭 I made F335M red because this is PAH, otherwise the entire image would be green. Full resolution: commons.wikimedia.org/wiki/File:LH...

Chaos! This *incredible* new #jwst image shows shells of dust emitted over the last 700 years by a system of 3 aging stars. The 2 main stars tear through space at an astonishing ~2000 MILES PER SECOND, whereas the 3rd star cuts through the dust like a knife. More: science.nasa.gov/missions/web...

Here’s an annotated version of our comet image. We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.

NASA's pix of the interstellar comet 3I/ATLAS are now up science.nasa.gov/solar-system... This is the HiRISE/MRO image ⬇️

Sh 2-140 is about 3000 light years away in the direction of Cepheus. An emission nebula, it is heated by young stars. The sharp edge along the bottom of the nebula marks a dark molecular cloud where new stars are forming. 8.2hrs, #Seestar S50 🔭 🧪 Siril, GraXpert, Starnet, GIMP

Last night (wednesday) the aurora was faint to my eyes, but glorious for the lens of my iphone.

I didn’t know it was this bad at Goddard. Infuriating. 🧪

The amazing thing was that this aurora was visible through thin clouds. I then shouted at the clouds and the sky cleared for an hour. You are welcome NE Ohio.

I've summarized the truth about Loeb's 10 "anomalies" about 3I/ATLAS in one post. Thanks to @deschscoveries.bsky.social @michael-w-busch.bsky.social @cometary.org and @marshall-eubanks.bsky.social for contributing their expertise!

Dear Physicists and Physics fans, I would like to encourage you to celebrate #WomenInPhysics Day this Friday, November 7th. Why November 7th? Because it is the birthday of two of the most impactful women physicists of the 1900's: Marie Curie and Lise Meitner. 🎢 ⚛️ 🧪 👩‍🔬

You've seen the news about issues at Goddard closing facilities and the culture of fear and intimidation. AGU has generated an email and a call script to contact your representatives. Please take a few minutes over your coffee this morning to send it. And thank you. agu.quorum.us/campaign/146...
