A new tool, referred to as a 'climate decoder', is being used to study the climates of potentially habitable exoplanets. The decoder may help identify signs of habitability, such as the presence of airborne dust, and could also potentially detect clues to catastrophic climate events on these distant worlds. The technology's capabilities and applications appear to be broad, with some outlets suggesting it could aid in the search for extraterrestrial life or the detection of technosignatures from other civilizations.
