To mark the start of the Dark Skies Festival today, here are some fantastic photographics taken not that far from Brighton.
A new biography of Vera Rubin by Ashley Jean Yeager. One for the wishlist!
This is a tagline I can get behind:
The cosmonaut counterparts of the Mercury women astronauts: Zhanna Yorkina, Irina Solovyova, Tatyana Kuznetsova, Valentina Ponomareva, and Valentina Tereshkova.
Ponomareva recalled there being no envy between the women in the squad. According to her, it was a healthy spirit of competition. Everyone did their best to be number one, but also supported each other’s efforts.
One of those cosmonauts went to space: none of the women training for the Mercury missions did. There would be a shockingly gap of twenty years between the launch of Valentina Tereshkova and the launch of Sally Ride.
Typography meets astronomy in 16th century books like the Astronomicum Caesareum.
It is arguably the most typographically impressive scientific manual of the sixteenth century. Owen Gingerich claimed it, “the most spectacular contribution of the book-maker’s art to sixteenth-century science.”
Push notifications explained using astrology. But don’t worry, there’s also some code, just in case you prefer your explanations to also include models that actually work.
So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.

I mostly stuck to Le Guin’s world-building rules for Winter, which were “no large meat-animals … and no mammalian products, milk, butter or cheese; the only high-protein, high-carbohydrate foods are the various kinds of eggs, fish, nuts and Hainish grains.” I did, however, add some hot-climate items found in Manhattan’s Chinatown for their space-age looks and good flavors (dragonfruit, pomelo, galangal, chilis, and kaffir limes).
Serve with hot beer.
A lovely interactive photo essay charting the results of what happens when evolution produces a life form that allows a planet to take selfies.
Steven Johnson dives deep into the METI project, starting with the Arecibo message and covering Lincos, the Drake equation, and the Fermi paradox.
He also wrote about what he left out of the article and mentions that he’s writing a book on long-term decision making.
In a sense, the METI debate runs parallel to other existential decisions that we will be confronting in the coming decades, as our technological and scientific powers increase. Should we create superintelligent machines that exceed our own intellectual capabilities by such a wide margin that we cease to understand how their intelligence works? Should we ‘‘cure’’ death, as many technologists are proposing? Like METI, these are potentially among the most momentous decisions human beings will ever make, and yet the number of people actively participating in those decisions — or even aware such decisions are being made — is minuscule.
When I was in Düsseldorf for this year’s excellent Beyond Tellerrand conference, I had the pleasure of meeting Nadieh Bremer, data visualisation designer extraordinaire. I asked her a question which is probably the equivalent of asking a chef what their favourite food is: “what’s your favourite piece of data visualisation?”
There are plenty of popular answers to this question—the Minard map, Jon Snow’s cholera map—but we had just been chatting about Nadieh’s previous life in astronomy, so one answer popped immediately to mind: the Hertzsprung-Russell diagram.
The Long Now Foundation has been posting some great stuff on their blog lately. The latest is a look at orreries, clocks, and computers throughout history …and into the future.

Building a planet-sized telescope suggests all sorts of practical difficulties.
Churchill, as it turns out, had some pretty solid ideas on SETI.
Churchill was a science enthusiast and advocate, but he also contemplated important scientific questions in the context of human values. Particularly given today’s political landscape, elected leaders should heed Churchill’s example: appoint permanent science advisers and make good use of them.
This is beautifully intimate. Your role is that of an anthropologist in orbit around Earth observing the everyday moments on the planet below through uploaded videos that have never been viewed by another human.
There’s going to be an evening of astro events out at Sussex University next Wednesday, January 18th. Stargazing, an inflatable planetarium, and the Ensonglopedia of science—fun for all the family!
