"JWST Observations Reveal Cosmic Birth and Planet Formation Secrets"
NASA's James Webb Space Telescope has provided evidence supporting the theory that icy pebbles drift inward from the colder parts of protoplanetary disks to form planets, confirming the connection between water vapor in the inner disk and the drifting of icy pebbles from the outer disk. This breakthrough discovery sheds light on the process of planet formation and opens up new possibilities for studying rocky planets. The observations were made using Webb's MIRI instrument, which revealed excess cool water in compact disks compared to large disks, supporting the theory of efficient pebble drift.
