NASA's Juno Catches 3 Waves of Jupiter's Polar Cyclones

This composite shows views of Jupiter's northern polar cyclones in three different wavelengths of light – microwave, visible, and ultraviolet – as captured by NASA's Juno mission. These differing perspectives allowed Juno scientists to deduce that all Jovian polar cyclones are not created equal. The infrared image, on the far right, was derived from data collected by the spacecraft's Jovian Infrared Auroral Mapper (JIRAM) instrument. The composite image at center was collected by the JunoCam visible-light imager. Though taken with separate instruments that record different wavelengths of light, both images depict Jupiter's northern polar storms as well defined and of similar size. The data on the left, collected by Juno's Microwave Radiometer (MWR), shows the polar storms in another light. MWR enables Juno to see deep into Jupiter by recording the planet's microwave emissions. In the MWR graphic, the polar storms at the 4 and 6 o'clock positions have bright microwave signatures, indicating they extend well beneath the cloud tops, at least 62 miles (100 kilometers) below. The size of those two storms is comparable to what's found in the visible light and infrared light images, but t
