used data obtained by the James Webb Space Telescope's Mid-Infrared Instrument to identify the presence of quartz nanocrystals in the upper atmosphere ofdue to its 3.7-day orbital period, meaning the extreme temperatures could cause unique chemical processes to occur within its atmosphere, but the astronomers were still surprised by the findings., who is a researcher at the University of Bristol in the UK and lead author of the study, which is comprised of more than three dozen co-authors.

What makes this discovery unique is that exoplanets have traditionally been found to possess magnesium-rich silicates such as pyroxene or olivine, but the discovery of just quartz within an exoplanet's atmosphere by JWST's MIRI could provide new insights into the formation and evolution of exoplanet clouds and their respective atmospheres.

While quartz was identified in this most recent study, WASP-17b's atmospheric composition mirrors traditional gas giant planets that exist both inside and outside our Solar System, as it is primarily comprised of hydrogen and helium.
