Before 2025, paleontologists had confirmed exactly two footprints anywhere in the world made by an adult Tyrannosaurus rex — one in New Mexico, one in Montana. Isolated prints, each capturing a single instant, with no way to tell how the animal that made them actually moved. That changed with a discovery in the badlands of […]

For the first time, astronomers have pointed NASA’s two flagship space telescopes at the same patch of sky beyond Neptune and let them work as a team. Hubble handled the visible light. Webb handled the infrared. Together, they picked out 27 previously unknown trans-Neptunian objects, or TNOs — small, icy bodies that drift in the […]

A team from the University of York and Curtin University, in Australia, has settled one of the most persistent puzzles in British archaeology: the exact origin of the towering standing stones known as the Devil’s Arrows, near Boroughbridge, in North Yorkshire. High-resolution geological analysis of microscopic minerals has confirmed that the three surviving pillars — […]

Long before anyone built a kiln on purpose, the ground itself may have shown people how. A new study argues that a wave of prehistoric wildfires in the southern Levant, more than 9,000 years ago, scorched the region so thoroughly that it left behind naturally baked clay — and that Neolithic communities, watching the aftermath, […]

Picture a moonless night, far from any city. Look straight at the point in the sky opposite the Sun — the antisolar point, where the Sun would appear if you could see it through the Earth. There, faintly, you might make out an oval-shaped glow, 8 to 10 degrees across. For scale, that’s roughly the […]
