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.<\/p>\n<p>Planets take shape inside disks of gas and dust surrounding young stars, but the supply of gas they depend on is temporary. New observations from NASA\u2019s 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.<\/p>\n<p>The study, led by Naman Bajaj of the University of Arizona and coauthored by SETI Institute scientist Uma Gorti, examined 72 young, Sun-like stars and their protoplanetary disks. It is among the largest studies of planet formation conducted with JWST and suggests that different kinds of winds dominate at different stages of a system\u2019s early development.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>JWST reveals that newborn planets are racing against powerful winds and radiation before their supply of planet-building gas disappears.
