They've reported that recent observations show Pluto's atmospheric pressure decreased by 16% between mid 2021 and July 2023. Credit: NASA/JHUAPL/SwRITracking Starlight to Watch an Atmospheric ChangeIt's difficult to study Pluto's atmosphere from anywhere in the Solar System beyond Pluto itself. That makes gathering data about Pluto's atmosphere a challenge, but it also has an upside: different observers in different regions will capture data about different parts of Pluto's atmosphere. Ultimately, despite these useful occultation measurements, many questions remain unanswered about Pluto's atmospheric changes in the coming decades.
