Lava planet's 'sunscreen' clouds reflect 75% starlight: Study

Astronomers have found a thick atmosphere around lava planet TOI-561 b, located 280 light-years from Earth. Observations suggest its clouds act like a 'sunscreen' by reflecting 75% of the starlight. "We would expect a heavily irradiated rocky planet...to have lost its atmosphere billions of years ago. Instead, the evidence suggests it still has a significant atmosphere today," a scientist said.
