These striking volcanoes exist only in the digital realm. They are the products of research by scientists who are using pictures generated by artificial intelligence to train image-recognition programs. Likewise, the lower of each pair of galaxies is AI-generated, and populated only by fake stars.

Great Bear Lake in northern Canada has been called “the last pristine arctic lake” by the United Nations Educational, Scientific and Cultural Organization (UNESCO), which last year designated it and its surrounding territory as the Tsá Tué Biosphere Reserve. While on assignment for The New York Times, Christopher Miller took this photograph of the lodges that some of the local Sahtuto’ine (‘Bear Lake people’) use for smoking fish and drying meat.

By combining images taken over seven years at the Keck Observatory in Hawaii, researchers produced this film of four planets orbiting the star HR 8799. Each planet is more massive than Jupiter, with orbits ranging from 40 to 400 years.

Animals on treadmills have a long and distinguished history in science. Hansjürgen Dahmen, Matthias Wittlinger and their colleagues tweaked an existing design that uses a spherical ball suspended in a jet of air to track the path and walking behaviour of an animal atop the globe. In a paper published last week3, the team describes using the treadmill to analyse the behaviour of Cataglyphis desert ants.

Astronaut Buzz Aldrin was the unexpected star of the show at the New York Men’s Fashion Week. The show, by designer Nick Graham, was apparently Mars themed. He’s Buzz Aldrin. He can do whatever he wants.
