NASA's Lunar Reconnaissance Orbiter discovered a 222-metre-wide crater on the moon formed by an asteroid or comet impact two years ago, making it the largest known impact crater created in recent times. The rare event, estimated to occur only once every 132 years, provides valuable data as NASA prepares to establish a crewed lunar base.
Weave is experimenting with using AI agents on a prediction market exchange to price the impact and utility of code pull requests, leveraging a central limit order book where agents can buy and sell based on their assessments of a PR's value relative to engineering time investment.
New simulations suggest the moon may have formed in as few as five hours after a Mars-sized protoplanet called Theia collided with early Earth. Researchers found that accounting for the geological properties and temperature of both bodies at collision—particularly their material strength—significantly affects how quickly the moon coalesced from the impact debris.
