00:00NASA's Bennu asteroid carries material from a surprising part of the early solar system.
00:05Instead of forming far out where comets took shape,
00:08Bennu likely emerged near the young sun's water ice line,
00:11a boundary where dust and ice mixed.
00:14Scientists analyzed 120 grams of Bennu's surface,
00:18returned by the OSIRIS-REx mission,
00:20and found its chemical fingerprint matches the asteroid Ryugu
00:24and rare carbon-rich meteorites on Earth.
00:26This link suggests Bennu formed from fine dust mixed across regions shaped by Jupiter's early influence.
00:33Jupiter acted like a barrier, sorting dust and allowing fine particles to combine near the ice line.
00:39That mixing explains Bennu's water content and offers clues about how Earth's building blocks formed.
00:45Yet researchers say the story isn't complete,
00:47and they're eager to compare Bennu's signature with other asteroids in future missions.
