Amateur astronomer questions Jupiter's atmosphere with old technique
Jupiter's Jupiter's cloud layers.
wavelengths to map the abundance of gases like ammonia and methane in Jupiter's atmosphere. As reported by space.com, the data revealed that reflective cloud layers are located at pressure levels of 2-3 bar, far deeper than where ammonia ice was expected to condense at 0.7 bar.
Patrick Irwin, a planetary physicist at the University of Oxford, reviewed Hill's results and confirmed their accuracy through comparisons with data from instruments such as NASA's Juno spacecraft and ESO's Very Large Telescope (VLT). He noted to space.com that the main reflection appears to stem from ammonium hydrosulfide clouds or photochemical products, rather than pure ammonia ice.
Reports indicate that these findings underline the role of photochemistry in shaping Jupiter's atmosphere, where ammonia is often destroyed faster than it can rise to the upper layers. Similar processes have been observed on Saturn, where cloud layers are also deeper than predicted. Researchers aim to refine models by integrating additional data from the VLT, Juno, and other observatories to better understand ammonia's vertical distribution.
Hill's approach demonstrates the potential of collaborative efforts between amateur and professional astronomers. These findings not only challenge existing models but also open new pathways for studying atmospheric dynamics on gas giants.
