So I’m reading about all year. I picked up Harry Cliff’s book which explains in terms the controversy in the expending universe. Definitely engaging. https://hollysreadingescapades.blogspot.com/2026/01/book-review-space-oddities-by-harry.html?m=1

It's Stephen Hawking's birthday. The occasion to share this fantastic video he produced as part of his Genius documentatry series. Hawking elaborates on our place in the Universe, including our membership to the Laniakea supercluster of galaxies that we discovered back in 2014.

An extract of a video produced by Stephen Hawking describing our cosmography and the hiearchy of structures to which we belong.

It is a starless, gas-rich, dark-matter cloud that is considered a ‘relic’ or remnant of early galaxy formation.

This week's at the library (the last one for 2025!): Three second-hand copies of Atlas of the Galilean Satellites from Cambridge University Press; the absolutely massive Fire and Mud: Eruptions and Lahars of Mount Pinatubo, Philippines from the University of Washington Press; and , Geologist from Cornell University Press which I might well review sometime soon in the new year in light of an upcoming Darwin biography...

A photo of three books standing on a small, brown, wooden table. The out-of-focus background shows black shelves full of books and part of the beech-coloured laminate floor. On the left, standing up, Atlas of the Galilean Satellites, showing a composite photo of four of Jupiter's large moons shown in crescent view, arranged left to right from small to large: Callisto, Ganymede, Europa, and Io, showing a tiny sulfur dioxide-rich volcanic plume in deep purple erupting from its surface. In the middle, lying down, Fire and Mud, a very thick hardback book, showing a colour photo of an agricultural field with in the foreground the tiny figures of an ox pulling a plough, followed by a human holding the reins. The background shows various white-roofed buildings against a background of hills. The top 80% of the photo shows the sky in which an enormous eruption cloud blossoms skywards. The dust jacket explains this is an early pre-climactic eruption at 0851h, June 12, 1991. In the middle, towards the bottom, is an inset colour photo showing a house surrounded by felled trees, all covered in a thick layer of volcanic ash. On the right, standing up, Charles Darwin, Geologist, showing a period black-and-white photo of a seated, middle-aged, balding Charles Darwin circa 1855, wearing a waistcoat. The bottom third of the photo shows a fold-out colour plate with three colourful cross-sections through the Cordilleras of the South American Andes mountains. The writing is too small to read.

We really ♥️ this piece from John Hawks on humans looking at the stars, especially how he picks up African cosmologies on the link of the to 🩸

Right now I'm involved in one of the MOST important papers of my life with Hadza hunter-gatherer experts on Hadza beliefs and practice around menstruation, hunting and the moon.

The key here is no one understands Hadza --their moon-scheduled ritual for healing and good hunting--unless they also understand menstrual beliefs and practice.
