Ancient Roman concrete arches contained volcanic ash, which helped them self-heal when cracks formed by reacting with water. This made them incredibly durable, lasting for millennia.
Asteroid Vesta is confirmed as the main source of most Earth meteorites, especially HED types (howardites, eucrites, diogenites). Its unique orbit and past collisions likely released fragments that reached Earth, enhancing our understanding of meteorite
A study shows up to 30% of Sun-like stars may engulf planets, altering their metallicity. These "polluted" stars suggest rocky planets are destroyed during orbital decay. Ultra-short-period planets in compact systems are key to understanding this pheno
NOAA’s solar coronagraph on the L-1 observatory is now active, improving solar monitoring by capturing the Sun’s corona to track phenomena like CMEs. This tool enhances space weather forecasting, which is crucial to minimize disruptions on Earth, suc
