The Jet Propulsion Laboratory's Juno probe is currently in an elliptical orbit over Jupiter's polar regions. In association with the Gemini Observatory on Mauna Kea in Hawai'i, images of the planet were recently captured in near-infrared wavelengths to correspond with a fly-by of the satellite. A series photographs was used to create a composite of the gas giant. The final IR image revealed haze over a range of altitudes, as observed in the reflected sunlight, as well as other details including Jupiter's Great Red Spot originally seen by Geovanni Cassini in 1665.

According to JPL, multiple filters were used to capture colors corresponding to different IR wavelengths. The final composite shows Jupiter's Great Red Spot as the brightest region (white) at these wavelengths. Other IR filters were sensitive to high-altitude clouds and hazes near and above the top of Jupiter's storms and cloud systems. Juno completed its 6th closest approach to Jupiter shortly after these measurements and telescope observations were made.
