Over 30 years of near infrared (NIR) observations at Uranus starting in 1992 with Trafton, et al., 1993, it is only in the last 5 years we have had any significant breakthroughs in mapping of NIR auroral morphology. The first confirmed auroral observ

Jupiter’s Polar Regions host a very strong auroral activity. The Jovian auroras leave their imprint in the ultraviolet spectral region, but also in the Mid-Infrared, which suggests that they can influence the thermal structure by heating up not onl

We present first results from the James Webb Space Telescope (JWST) observations of Uranus, which provide the first spatially resolved, infrared spectra of the planet’s atmosphere spanning from 1.66 to 28.6 µm. We evaluate these unprecedented JWST

In 2012, ground-based observations of the dominant molecular ion in gas giant ionospheres, H3+, found that Jupiter’s upper atmosphere was super-heated above its iconic Great Red Spot (GRS). Temperatures there reached 1600 K, hotter even than the au

Introduction Continued monitoring of Jupiter during the past four decades from Earth-based observatories, the Hubble Space Telescope, and visiting spacecraft has provided essential insights on Jupiter's belt/zone structure from the upper stratosphere

In this talk, we present highlights from our recent analyses of mid-infrared observations of Uranus and Neptune, and we look ahead to anticipated discoveries from the James Webb Space Telescope. Drawing from a combination of archival and recent groun

Ground- and space-based remote sensing, from Voyager, to Galileo, Cassini and Juno, has revealed the existence of circulation cells in the troposphere of Jupiter. These circulation cells, which may be similar to terrestrial Ferrel cells [1], show pro

H3+ measurements at Uranus have but recently shed light into the morphology of Uranus’s infrared aurora. Observations in late-2006 by Thomas, et al., in review showed enhanced emissions in the northern hemisphere similar in latitudinal range to the

Jupiter's extended disc and infrared brightness create a challenging target for JWST's MIRI instrument to probe. Observations with the Medium Resolution Spectrometer (MRS) integral field units are expected to saturate beyond 11 microns, and the field

Since 2016 the Juno spacecraft has been in orbit around Jupiter, gathering unprecedented data from its highly inclined 53-day orbit. The Jupiter Infrared Auroral Mapper (JIRAM) is an imager and spectrograph with spectral coverage between 2 and 5 µm.
