A recent study suggests that many 'Mini-Neptune' exoplanets might be surrounded by thick, hazy clouds of soot, reminiscent of the smog found on Earth.
This finding contrasts sharply with the stunning images of Earth taken by astronauts on the Artemis mission, which showcase clear views of the planet's landscapes.
The implications of this research could expand our understanding of atmospheric conditions on distant planets, highlighting the diversity of environments in the universe.
