PIX4625625: Tethys, Saturn satellite, seen by the Cassini probe - Saturn's moon Tethys seen by Cassini spacecraft: The Tethys satellite photographed by the Cassini probe on 11 April 2015 has a distance of 53,000 km from the satellite. Tethys is about 1070 km in diameter. - This enhancement-color mosaic of Saturn's icy moon Tethys shows a range of features on the moon's trailing hemisphere. Tethys is tidally locked to Saturn, so the trailing hemisphere is the side of the moon that always faces opposite its direction of motion as it orbits the planet - Images taken using clear, green, infrared and ultraviolet spectral filters were combined to create the view, which highlights subtle color differences across Tethys' surface at wavelengths not visible to human eyes. The moon's surface is fairly uniform in natural color - The color of the surface changes conspicuously across the disk, from yellowish hues to nearly white. These broad color changes are affected by a number of external processes. First, Saturn's diffuse E-ring preferentially bombards Tethys' leading hemisphere, towards the right side of this image, with ice bright ice grains. At the same time, charged particles from Saturn's radiation belt bombard the surface on the trailing side, causing color changes due to chemical alteration of the materials there. The albedo - a measure of the surface's reflectivity - drops by 10 to 15 percent from the moon's leading side to the trailing side. Similar global color patterns exist on other Saturnian moons - This mosaic is an orthographic projection constructed from 52 Cassini images obtained on April 11, 2015 with the Cassini spacecraft narrow-angle camera. Resolution is about 1,000 feet (300 meters) per pixel. The images were obtained at a distance of approximately 33,000 miles (53,000 kilometers) from Tethys / Bridgeman Images

PIX4626477: Remains of supernova located about 1400 light years ago in the constellation Swan. The supernova would have exploded less than 10,000 years ago. Image obtained by the Oschin telescope of Mount Palomar through several filters and composed - The Veil Nebula, also known as the Cygnus Loop, is a large supernova remnant, relatively faint supernova remnant in the constellation Cygnus. The source supernova exploded some 5000 to 8000 years ago. The distance to the nebula is not precisely known, with estimates ranging from 1400 to 2600 light years. It was discovered on 1784 September 5 by William Herschel. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory.: Les laces du Swan - The Veil nebula / Bridgeman Images
