What happened
JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas disappears, giant planets face a shrinking window to build massive atmospheres.
Science News from research organizations James Webb reveals why planet formation is a race against time JWST reveals that newborn planets are racing against powerful winds and radiation before their supply of planet-building gas disappears.

New observations from NASA's James Webb Space Telescope (JWST) are giving astronomers a clearer picture of how that gas escapes and how the dominant escape mechanisms change as planetary systems mature. Nearly all of that gas eventually disappeared.
