If Earth was built close to the young Sun, where did its water come from? New isotope analysis rewrites part of Earth’s origin story and gives scientists a new mystery to solveNew analysis suggests Earth formed solely from inner Solar System material. This challenges previous theories about outer Solar System cont...- In 2026, scientists recreated 15,000 years of solar wind exposure on Moon soil in 4 hours; the experiment could help with future lunar resource miningInterlune has recreated the effects of around 15,000 years of solar-wind exposure on lunar soil in just four hours, using accelerated heliu...
- In 2004, NASA’s Genesis sample capsule crashed in Utah at up to 193 miles per hour; scientists later recovered valuable solar-wind samplesNASA's Genesis mission faced a dramatic mishap in Utah when its capsule crashed after gathering precious solar wind samples. The failure of...
- In 1969, Australia recovered the Murchison meteorite after it fell near Victoria. Years later, scientists studied stardust hidden inside and discovered grains dating back roughly 7 billion years, before the Solar System existedThe Murchison meteorite carried something far older than Earth. Scientists found tiny silicon carbide grains inside it that formed nearly 7...
