Exoplanets are planets that orbit stars outside of our own Solar System. The discovery and study of these distant worlds have revolutionized our understanding of planetary formation and the potential for life beyond Earth.
Venus is often called Earth's twin, but spend any time with it and the comparison falls apart quickly. Its surface is hot enough to melt lead, its atmosphere is a crushing blanket of carbon dioxide, and its clouds are made of concentrated sulphuric acid. Somewhere beneath those acid clouds, between the surface and the main cloud deck at around 47 kilometres up, a thin mysterious haze has drifted for billions of years, stubbornly resisting every attempt at explanation. Until now.
