Scientists expect to characterize the state of Jupiter’s atmosphere from high-resolution observations obtained by amateur astronomers. By comparing images of Jupiter obtained from different locations on Earth over time, they can observe the same areas of the planet repeatedly and obtain information such as the intensity of the winds and the activity of storms in the planet. The image on the left was obtained using a 40 cm diameter telescope and a fast black and white camera equipped with colour filters by Damian Peach during a trip to Barbados. The image on the right was obtained by Christopher Go from the Philippines using similar equipment. Credit: D. Peach/C. Go
