Israel & Saudi Arabia pushed the U.S. to attack Iran. Netanyahu killed 72,000 people in Gaza, mostly women & children. Saudi Arabia is a brutal dictatorship that allows no opposition. These are the leaders who want to bring “freedom” to Iran? Does anyone really believe that?

Some academic papers show everyone how people are posting about the paper, using a tool called Altmetric. Here's the how our new paper reached folks on twitter vs. bluesky. No comparison. Twitter is gone gone. Deader than the Monroeville Mall in The Dawn of Dead. www.nature.com/articles/s43...

A view we will not soon forget. The Blizzard of 2026.

Millions of people in New York City and a large swath of the northeastern U.S. were stuck at home under road travel bans and blizzard warnings on Monday as a fierce winter storm barreled into the densely populated region with heavy snowfall and high winds.

I spent a couple more nights gathering light on Thor's Helmet. There are some bits that I'll want to change later and when I do, I'll update the thread with new versions. Let me know which version you like more: the lighter blue HOO or the darker blue SHO. #astrophotography #photography

Two's company ⭐️⭐️ Just like we humans are strongly influenced by the presence of companions over the course of our lives, so are stars, literally. The pair of points at the centre of this image, taken with our VLT, are an old stellar couple known as AFGL 4106.  🔭 🧪

No matter how bad the weather is here, it's nothing compared to conditions on Uranus. There, winter means 40 years of darkness & auroras that follow the planet's tilted, twisted magnetic field. JWST just provided the best look yet at those Uranian aurora displays. 🧪🔭 esawebb.org/news/weic2602/

First a hydrogen leak. Now a separate *helium* leak is causing a delay in NASA's Artemis 2 mission around the Moon. The giant rocket is rolling off the launch pad, with the flight delayed to April 1 at the earliest. 🧪🔭 spaceflightnow.com/2026/02/21/n...

Let's try this again 👋 Hi Bluesky - I'm Massachusetts' Attorney General. You might know me from suing President Trump nearly 50 times, beating Uber and Lyft in court, or being the first woman of color elected to statewide office in MA. I officially left X today - help me find my MA people?

someone please tell me drawing all of these weird Cambrian guys will be worth it

Today we’re launching Open Climate Risk, a fully open option for U.S. building-level climate risk data. It’s unique because it allows you to see not only risk scores, starting with wildfire, but also the complete underlying dataset, methods, and codebase. carbonplan.org/research/cli...

v1.116 is rolling out now! For all the overthinkers and perfectionists out there, we're launching Drafts.

Did u know? Having a wildlife garden means minimising waste & re-using as much as poss. Live by the mantra - whatever grows in the garden, stays in the garden. Don't take dead wood or logs to the tip,pile them up in your outside space to create fabulous habitats for all sorts of small souls. 🌿🌱🇬🇧🌱🌍🪲🪵

Lowest US Western snow-pack since 2001 (MODIS data)

The western U.S. faces its lowest snowpack on record despite average or above-average rainfall. Warmer temperatures mean more precipitation falls as rain rather than snow, and will worsen droughts in areas like the Pacific Northwest and the Colorado River Basin. science.nasa.gov/earth/earth-...

After hearing today’s news & knowing Alex Pretti - dry January is over. In my ICU rotations at Minneapolis VA, nights in residency, & days as a fellow in infectious diseases, I worked alongside Alex. Surely our nurses unions can help make some good trouble for a fallen hero? #Neat #NoICE #MedSky

US about to get a master craft lesson in albedo.

Anyone know a good weather site better than Weather[dot]com, whose interface isn't a steaming pile of poo and ads? I already have wunderground but looking for a more "every person's" site.

Remember kids, don’t eat raw milk: “The milk from the previously infected cow was not processed for human consumption. However, the virus generally becomes inactive when the milk is pasteurized, and the milk from this farm is only used for pasteurized products.“ www.melkvee.nl/artikel/1447... 🧪🛟

First evidence in Europe of highly pathogenic avian influenza virus H5N1 infection in a dairy cow. Antibodies against H5N1 detected in a cow with mastitis and respiratory signs on a Dutch dairy farm at the end of December. A cat on that farm had died from H5N1. www.tweedekamer.nl/downloads/do...

Impressive aurora seen from Potsdam, Germany (here facing south with Orion)! #Polarlichter #astrophotography 🔭

The sun is going bonkers. Hop outside + hunt for those auroras. Check out the current image from KHO in Svalbard 🔭🧪

Tonight's aurora from Antwerpen, Belgium! quite rare spectacle. Started out very green, then pink-purple before it subsided just like an hour ago. 🧪 🔭

Let’s check in on the solar cosmic ray count at Mawson station following the big CME event and everything looks norm— Oooooft. 🔭

Everything Trump says here is verifiably untrue. During this period of time the number of US installations on Greenland went from 17 to 1 as a result of US determinations that they were not needed.
