Astronomers left puzzled by high-altitude clouds forming on young planet

SMRTR summary

Astronomers using the James Webb space telescope observed two gas giants orbiting a young star 307 light years away. The outer planet, YSES-1c, has high-altitude clouds of mineral dust and possibly iron, while the inner planet, YSES-1b, is surrounded by a mysterious disc of material. These findings challenge current theories of planet formation and provide valuable data for refining models of early planetary evolution.
