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.

I’ve made no secret of my admiration of Jocelyn Bell Burnell, and how Peter Saville’s iconic cover design for Joy Division’s Unknown Pleasures always reminds of her.
There are many, many memetic variations of that design.
I assumed that somebody somewhere at some time must have made a suitable tribute to the discover of those pulses, but I’ve never come across any Jocelyn-themed variation of the Joy Division album art.
The test order I did just showed up, and it’s looking pretty nice (although be warned that the sizes run small—I ordered a large, and I probably should’ve gone for extra large). If your music/radio-astronomy Venn diagram overlaps like mine, then you too might enjoy being the proud bearer of this wearable tribute to Dame Jocelyn Bell Burnell.

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.

Recipes inspired by The Left Hand Of Darkness.
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.

60 seconds over Idaho
I lived in Germany for the latter half of the nineties. On August 11th, 1999, parts of Germany were in the path of a total eclipse of the sun. Freiburg—the town where I was living—wasn’t in the path, so Jessica and I travelled north with some friends to Karlsruhe.
The weather wasn’t great. There was quite a bit of cloud coverage, but at the moment of totality, the clouds had thinned out enough for us to experience the incredible sight of a black sun.
(The experience was only slightly marred by the nearby idiot who took a picture with the flash on right before totality. Had my eyesight not adjusted in time, he would still be carrying that camera around with him in an anatomically uncomfortable place.)
Eighteen years and eleven days later, Jessica and I climbed up a hill to see our second total eclipse of the sun. The hill is in Sun Valley, Idaho.
Travelling thousands of miles just to witness something that lasts for a minute might seem disproportionate, but if you’ve ever been in the path of totality, you’ll know what an awe-inspiring sight it is (if you’ve only seen a partial eclipse, trust me—there’s no comparison). There’s a primitive part of your brain screaming at you that something is horribly, horribly wrong with the world, while another part of your brain is simply stunned and amazed. Then there’s the logical part of your brain which is trying to grasp the incredible good fortune of this cosmic coincidence—that the sun is 400 times bigger than the moon and also happens to be 400 times the distance away.
This time viewing conditions were ideal. Not a cloud in the sky. It was beautiful. We even got a diamond ring.
I like to think I can be fairly articulate, but at the moment of totality all I could say was “Oh! Wow! Oh! Holy shit! Woah!”
Our two eclipses were separated by eighteen years, but they’re connected. The Saros 145 cycle has been repeating since 1639 and will continue until 3009, although the number of total eclipses only runs from 1927 to 2648.
Eighteen years and twelve days ago, we saw the eclipse in Germany. Yesterday we saw the eclipse in Idaho. In eighteen years and ten days time, we plan to be in Japan or China.

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.

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!
