James Webb Space Telescope observations reveal that planet formation must occur within a limited time window.

What it means

JWST observations of 72 young Sun-like stars reveal that the gas needed to form giant planets like Jupiter is rapidly stripped away from protoplanetary disks by a combination of powerful jets and molecular winds. This means planet formation must happen within a few million years before the gas disperses, making it a race against time for gas giants to assemble.

Accuracy & sourcesGrounded

The claim is based on a peer-reviewed study led by Naman Bajaj (University of Arizona) and co-authored by SETI scientist Uma Gorti, using JWST data from 72 young star systems. Science Daily's reporting is a reputable secondary source that closely summarizes the primary research, so the core finding is solid, though the exact timescale may depend on modeling assumptions.
