Star City Spoiler: so if For All Mankind is all about Mars and war, Spy City is ultimately about love and Venus. Nicely done.

Today in 1955, Bertrand Russell issued the Russell-Einstein Manifesto in London, calling upon every government on Earth to prevent a nuclear war by publicly renouncing war, abolishing thermonuclear weapons, and pursuing “peaceful means for the settlement of all matters of dispute between them.”

Students have long been given the idea that the goal of taking classes is to get good grades, learning is just a side effect. Now it’s not even a side effect.

This beautiful infrared image from JWST shows a piece of the sword of Orion, just north of the Orion Nebula. Hidden to our eyes, this inconspicuous patch of sky is furiously forming stars - more rapidly than any other region within 1500 light years. esawebb.org/images/potm2...

This is absolutely astonishing - it's rare in astronomy to see so much change on a human timescale, but this really shows how dynamic the gas and dust around a young star can be. Seeing the shadows from the inner regions cast out onto the outer spiral arms, amazing!

Entering the grand halls of the NAS I felt a potent mixture of awe and fury. Science is so amazing. Not just for its material discoveries, but also for what it reveals about human values and our ability to know the world *together*. Shame on everyone who is complicit in this crisis. >>

Wait, is that the Moon out beyond the Moon? And is the ISS out in lunar orbit or something?! Man, fire your AI provider... bsky.app/profile/redd...

Well, isn’t this a sight for sore eyes! 😍 Our beloved Hubble appears in this amazing image from one of Vantor's WorldView Legion satellites. It was 36 years ago today that Hubble was launched in the bay of the Space Shuttle Discovery from NASA’s Kennedy Space Center. Credit: Vantor.

Today is a good day to remember that Carl Sagan was as outspoken about the dangers of war and nuclear weapons as he was an advocate of space exploration.

This is one of a series of prints of Opabinia, 🧪🐡 an extinct prehistoric creatures which lived during the Cambrian geological time period, carved by hand in linoleum, printed onto lovely white paper with bark inclusions and collaged with Japanese papers in different colours and patterns, 🧵

Titan, Saturn’s largest moon, was discovered on March 25, 1655, by Christiaan Huygens. More than 350 years later, it remains a key target for exploration. Launching in 2028, NASA’s Dragonfly mission will investigate the complex chemistry of this ocean world. https://dragonfly.jhuapl.edu/Why-Titan

Tonight in 1983 in the Oval Office, President Ronald Reagan called on “the scientific community in our country” to develop a defensive shield to render strategic nuclear ballistic missiles “impotent and obsolete.” More than $494 billion later (fiscal year 2026 dollars), his dream remains just that.

Looking at the AAS jobregister lately, it seemed to me that there are less positions available in all categories than in previous years. Wanting to quantify, I used the wayback machine to check on the number of postings in the January-March window and it is quite depressing.

I keep seeing versions of this post, which imply a bizarre misunderstanding of how we know the world. Do people really imagine that if we'd never observed galaxies or neutrinos or exoplanets or the cosmic microwave background, we could have *imagined* these things & that would be just as real? 🧪

I talked to a lead NSF program officer (PO) who’s considering quitting because everything’s terrible. This is part of the apocalypse. POs don’t just give out money. They keep up with their scientific field and everyone in it to ensure that there’s balance in who and what’s funded. It’s bad news.

mmm #arXiv is leaving Cornell university, becoming independent, and hiring a CEO. Should we worry? I'm already worried.

The world would be a better place if journalists and lawmakers can distinguish an ebike from an electric motorcycle.

The @axisprobe.bsky.social team learned that the phase A concept study report of AXIS (the Advanced X-ray Imaging Satellite) will not be reviewed because the lost personnel at NASA Goddard and government shutdown impacted our schedule and budget. 🔭 Here is the PI's e-mail with the explanation.

In Koblenz ist ein Meteorit in ein Hausdach eingeschlagen, auch im Hunsrück und in der Eifel hat der ehemalige Himmelskörper Schäden angerichtet. Augenzeugen berichten von einem hellen Flugkörper – verletzt wurde niemand.

Alerts from NSF–DOE Rubin Observatory have been flowing for about a week...how many have there been?? 🚨 So far, Rubin has generated....drumroll please🥁 ~1.7 million world-public alerts! That's ~1.7 MILLION objects that changed in brightness or position in just seven nights 🤯 🔭🧪

Tonight in 1959, “The Twilight Zone” episode “The Monsters Are Due On Maple Street” (season 1, episode 22)—Rod Serling’s taut and unforgettable Cold War parable depicting the societal consequences of irrational fear and paranoia of communist infiltration—was broadcast for the first time on CBS.

Scientific American has updated the figure, now grouped into swimmers, fliers, walkers/runners, and vehicles. A person on a bicycle remains the most efficient way to travel, compared to all forms of biological locomotion and mechanical transport. www.scientificamerican.com/article/a-hu...

Wowowow - our @science.esa.int Hubble's picture of the month for March is the Cat's Eye Nebula, from combined images of #Hubble and #Euclid. Euclid's wide field and low surface brightness sensitivity brings out an external shell. Incredible image. esahubble.org/images/potm2... 🔭

80% of agricultural land is used for livestock (and textiles), yet this huge land use provides only 17% of our calories and 38% of our protein. 16% of the land used for crops provides 83% of our calories and 62% of our protein. It's past time we rethink what we eat.

Mondays are better with an octopus squid 🦑💫⁠ ⁠ The octopus squid (Octopoteuthis deletron) is unusual among squids. Most squids have eight arms and two long tentacles, making a total of 10 appendages. As young Octopoteuthis mature, their two feeding tentacles are reabsorbed into their bodies.

EVs now represent more than 10% of new car sales in 39 countries, including Vietnam at 38% and Indonesia at 15%. In the U.S., that figure is less than 10%. The gap signals a competitive problem that goes far beyond climate – it's about who controls the future of automotive jobs. buff.ly/H5ETTBQ
