Nut’s cosmological vignette on the outer coffin of Nesitaudjatakhet in the collection of Odessa Archaeological Museum OAM 52976 (C107). Nut’s body is covered in stars as well as a thick, undulating black curve that runs from the soles of her feet to the tips of her fingers. This curve, surrounded by stars on both sides, is reminiscent of the Milky Way’s Great Rift. Credit: Mykola Tarasenko; Odessa Archaeological Museum, NASU

A photomosaic taken by the Curiosity Rover on April 30, 2023 at the Ubajara drill site in Gale Crater, Mars. Rock powder samples drilled here contained substantial amounts of siderite (an iron carbonate mineral). The siderite played a role in ancient carbon cycling processes that impacted conditions at the planet’s surface. Rover tracks in the foreground are 40 cm wide. (Credit: NASA/JPL-Caltech/MSSS)
