A new screw-driven robot prototype can autonomously navigate and mine rocky planets like Mars using Archimedean screws, ideal for challenging surfaces like sand and snow. Developed with EU support, it holds potential for extraterrestrial mining missions.
A proposed array of 200 small telescopes could detect Planet Nine by observing stellar occultations. Spaced across 1,000 km, they’d map Trans-Neptunian Objects and potentially confirm a planet or primordial black hole in the solar system’s outer reac
The Mongols Created the First International Postal System

Women have bigger butts than men because of their hormones!
This swell toward the bottom is directly linked to evolution, indicating a woman is able and ready to reproduce.
