Interstellar Comet 3I/ATLAS experienced a dramatic increase in activity after its closest approach to the Sun, with all types of ice sublimating and releasing organic molecules like water, carbon dioxide, and hydrocarbons. This suggests a unique formation history and composition.
Scientists have discovered new complex organic molecules spewing from Saturn’s moon Enceladus, indicating complex chemical reactions within its underground ocean and strengthening the case for a dedicated ESA mission to the moon.
