Today is the December Solstice, the day on which the sun reaches its southernmost excursion on the celestial sphere.
In the Northern hemisphere, where it marks winter's dawn, people have observed the solstice for 10,000 years. In a 02013 paper, a group of archaeologists found that the Warren Field site in Scotland served as a lunisolar calendar synchronized to the solstice. DOI:10.11141/ia.34.1
Other neolithic solstice monuments include Newgrange in Ireland and Stonehenge in England, both of which began their construction around 3100 BCE.
A millennium later, the builders of the Precinct of Amun-Re at the Karnak Temple complex in Egypt also designed their space with deference to the Winter solstice.
In the Americas, many petroglyphs are connected to the solstice, with the Sun Dagger drawn by the Ancestral Pueblo people in Chaco Canyon being the best known example.
Winter solstice feasts are some of the oldest still-celebrated rituals around the world. In Iran, Yaldā Night commemorates the longest night of the year with poetry & food, while in China the Dongzhi Festival celebrates the solstice with colorful rice balls & large family meals.
Whatever you do to mark the solstice, you are connecting with a human lineage of time-keeping that stretches back ten thousand years. Here’s to many more solstices to come.

When astronauts see Earth from space, they experience a feeling of awe and awakening known as the "Overview Effect."
When we see images of the whole Earth from space, we can tap into some of that feeling of awe – and use it to make our planet a better place.
The first Earth Day in 01970 was inspired by @NASA's release of the first human-captured photos of Earth from Space in 01968.
The organizers of Earth Day celebrations all over the planet used the image of our planet from space as symbol of unity: humanity, together.
Two years before NASA released the first images of Earth from space, Long Now Co-founder Stewart Brand asked a single question that would prove epochal: "Why Haven’t We Seen A Photograph of the Whole Earth?" longnow.org/ideas/whole-ea…
The Dead Sea scrolls are still readable 2 millennia after their creation — yet the expected shelf life of a DVD is just 100 years. Without maintenance, most digital information will be lost in just a few decades.
How might we secure our data so that it survives for generations?
Adrienne Bernhard (@adrienneeve) takes a look into the challenge of preventing the Digital Dark Age to come, and at the organizations like the @InternetArchive, @GitHub, and @Permanentorg working to preserve data for generations to come. longnow.org/ideas/shining-…
@AdrienneEve @internetarchive @github @permanentorg People have long claimed that "the internet is forever."
In practice, that's not the case. We develop a false sense of security around digital files, their intangibility & seemingly infinite ability to be copied misleading us into thinking that we've made permanent records.
From 02021-02022 @berggruenInst Fellow Johanna Hoffman: How Iceland's most devastating volcanic eruption helped create a civic mythology of resilience, adaptation and celebration of nature. longnow.org/ideas/02022/09…
In 01783, Iceland burned.
The Laki volcano erupted and wrought devastation in the 218 square miles of lava it unleashed & the dire famine that came in its wake.
Yet this devastation left a legacy of hope, spurring Iceland towards an ethos of resiliency. longnow.org/ideas/02022/09…
Iceland, one of the last places in Europe to become inhabited by humans, was long known as a hotbed of volcanic activity, often in the form of cataclysmic eruptions.
Good evening everyone! Welcome to tonight's Long Now Talk featuring Kim Stanley Robinson on Climate Futures: Beyond 02022. Q&A follows with Kim Stanley Robinson and @ramez streamed live on YouTube at
@ramez Long Now continues our dialogue with the acclaimed writer Kim Stanley Robinson around climate futures, his attendance of COP26 and his most recent book The Ministry for the Future. indiebound.org/book/978031630…
Tackling topics from carbon quantitative easing, to political action, to planetary-level engineering, Robinson describes our current situation as one requiring "all-hands-on-deck" action, where every possible mitigation strategy should be tried.
Starting soon: Join us for a Long Now Talk with architect & designer Neri Oxman exploring her work in Material Ecology — the fusion of nature & technology. The talk will be followed by a conversation with Oxman and Long Now co-founder Danny Hillis.
The live stream will begin shortly.
