Natal disk PDS 70 and fledgling exoplanet PDS 70b
The natal disk PDS 70 with new fledgling gas-giant exoplanet PDS 70b (bright spot on right). Astrophysicists using instrumentation at the W.M. Keck Observatory uncovered a mismatched composition of gases in the planet’s atmosphere compared to gases within the disk, potentially confirming long-held skepticism that scientists' current model of planet formation is too simplified.
