Nasa Artist Concept of Lunar Prospector

These artist's concepts of Tempel 1 simulate an optical view of the comet (left), next to the simulated infrared view (right). The images illustrate the comet's shape, reflectivity, rotation rate and surface temperature, based on...

This is an artist’s concept of the extrasolar planet HAT-P-7b. It is a "hot Jupiter" class planet orbiting a star that is much hotter than our Sun. For its millionth observation, the NASA/ESA Hubble Space Telescope’s was trained on this...

This artist's concept shows the NASA/ESA Hubble Space Telescope in orbit around the Earth. The telescope's current appearance is the result both of its original design, and the modifications made during five servicing missions. In...

This is an artist's concept of a craggy piece of solar system debris that belongs to a class of bodies called trans-Neptunian objects (TNOs). Most TNOs are small and faint, making them difficult to spot. Generally, they are more than 100...

This artist's conception illustrates the brown dwarf named 2MASSJ22282889-431026. The NASA/ESA Hubble and Spitzer space telescopes observed the object to learn more about its turbulent atmosphere. Brown dwarfs are more massive and hotter...
