James Webb Discovers Lava Planet with Protective Atmosphere

• James Webb Space Telescope discovered a lava planet 280 light-years away reflecting 75% of incoming starlight.
• The planet, TOI-561 b, has a thick atmosphere that should have dissipated long ago.
• Mineral clouds on the planet act as a 'giant sunscreen', reflecting starlight.
• This discovery challenges current understanding of atmospheric retention on such planets.
• Further study is needed to understand the planet's atmosphere and its protective mechanism.
