Jupiter and Io, New Horizons image
Jupiter and Io. Montage of images of Jupiter (left) and its moon Io (right), obtained by the New Horizons spacecraft in February and March 2007 as it passed Jupiter on its way to Pluto. The image of Jupiter was obtained with its infrared spectrometer (LEISA). The different colours show high-altitude clouds (blue), and deeper clouds (red). The Great Red Spot (lower left) is blue and white. The Io image was obtained in approximate true colour with a long-range camera (LORRI) and a multispectral camera (MVIC). The red dot on the nightside of Io is an eruption of the Tvashtar volcano. The volcanic plume (blue) seen above the eruption is 330 kilometres high. Jupiter is the solar system's largest planet.

Syrian Desert, satellite image
Syrian Desert, satellite image. North is at top. Vegetation is red and dark green, while arid areas of sand and rock are light green and light blue. Water is blue. At centre is Jabal Sis, a huge extinct volcanic crater rising 100 metres above the surrounding plain. This area, part of the Syrian Desert, is in south-western Syria, near the border with Jordan. The water flow patterns on the landscape are evidence of seasonal flooding that supports the sparse vegetation in this area. The area shown in this image is around 100 kilometres wide. The image data includes infrared wavelengths, and was obtained on 6 November 2000, by the Landsat 7 satellite.

Comet 65P-Gunn, infrared image
Comet 65P-Gunn, infrared image. This comet is a short-period one (6.79 years) that orbits the Sun inside the main asteroid belt between the orbits of the planets Mars and Jupiter. It was discovered in 1970. This observation was made by NASA's Wide-field Infrared Survey Explorer (WISE) on 24 April 2010 (just one month after its closest approach to the Sun) in the constellation Capricornus. The comet (red) is colder in infrared than the surrounding stars (blue). Here, the comet is 392 million kilometres from Earth. Just ahead of the comet is a debris trail (fuzzy, red) along its orbit, a stage in the formation of a meteor shower.
