This false-color image shows the dwarf planet Ceres. Scientists use false color to examine differences in surface materials. The color blue on Ceres is generally associated with bright material, found in more than 130 locations, and seems to be consistent with salts.

This image of Jupiter was taken on August 23, when Juno was 2.8 million miles (4.4 million km) from the gas giant on the inbound leg of its initial 53.5-day capture orbit. The image is a color composite taken with JunoCam’s visible red, green, and blue filters. Bright features like the planet’s Great Red Spot are higher in the atmosphere, and so have less of their light absorbed by the methane. Image credit: NASA / JPL-Caltech / SwRI / MSSS.

Artist’s concept of the mechanism of heating from the Great Red Spot. Turbulent atmospheric flows above the storm produce both gravity waves and acoustic waves. Gravity waves are much like how a guitar string moves when plucked, while acoustic waves are compressions of the air (sound waves). Heating in the upper atmosphere 500 miles (805 km) above the storm is thought to be caused by a combination of these two wave types ‘crashing’ like ocean waves on a beach.
