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.

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up the planet’s surface.

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.

This composite image shows an infrared view of Titan. In this image blue represents wavelengths centered at 1.3 microns, green represents 2.0 microns, and red represents 5.0 microns. A view at visible wavelengths would show only Titan’s hazy atmosphere; the near-infrared wavelengths in this image allow Cassini’s vision to penetrate the haze and reveal the moon’s surface. The view looks toward terrain that is mostly on the Saturn-facing hemisphere of Titan. Image credit: NASA / JPL-Caltech / Space Science Institute.
