Ammonia-rich hail sheds new light on Jupiter’s weather
New Juno results suggest that the violent thunderstorms taking place in Jupiter’s atmosphere may form ammonia-rich hail, or ‘mushballs,’ that play a key role in the planet’s atmospheric dynamics. This theory, developed using data from Juno’s microwave radiometer by the Juno team, is described in two publications led by a researcher at the Laboratoire Lagrange (CNRS/Observatoire de la Côte d’Azur/Université Côte…

This brown dwarf might look a lot like Jupiter
The cloud bands on brown dwarf Luhman 16A were found via instruments known as polarimeters. An astronomer said they’re like “… an astronomer’s polarized sunglasses. But instead of trying to block out that glare, we’re trying to measure it.” Source: https://earthsky.org/space/brown-dwarfs-banded-clouds-luhman-16a-vlt…
Scientists Get Their Best-Ever Look At Jupiter’s Atmosphere and Storms
Scientists have gotten their most detailed view of the wild storms that swirl through the gas giant’s atmosphere. Space.com reports: Every 53 days, Juno skims over Jupiter’s cloud tops in a close approach called a perijove, gathering data all the while. Among the spacecraft’s instruments is a microwave radiometer, which is tuned to identify lightning strikes and study what ammonia and…
