Wildfires Seen From Station
A video camera aboard the International Space Station captured this footage of the wildfires burning in the Western U.S., including Colorado.

This artist's rendering illustrates the evaporation of HD 189733b's atmosphere in response to a powerful eruption from its host star. NASA's Hubble Space Telescope detected the escaping gases and NASA's Swift satellite caught the stellar flare.

A possible scenario for the internal structure of Titan, which includes a global subsurface ocean beneath an icy outer shell, as inferred by radio science data collected by the Cassini spacecraft.

The large 25 km-diameter crater in the foreground of this High Resolution Stereo Camera (HRSC) perspective view has excavated rocks which have been altered by groundwater in the crust before the impact occurred.

a, Topography in km; b, percentage of time illuminated; c, 10-m baseline slopes in degrees; d, surface roughness shown as RMS residual in m; e, locations of crater counts used to determine relative ages; and f, zero-phase, 1,064-nm reflectance shown as I/F. Topography, slopes and roughness are based on a 10-m spatial resolution grid of all available LOLA profiles. In a–d and f, x and y axes indicate spatial scale, where (0, 0) is the lunar south pole and colour scales show magnitude of plotted quantity.

Seeing is believing, except when you don't believe what you see.Astronomers using NASA's Hubble Space Telescope have found a puzzling arc of light behind an extremely massive cluster of galaxies residing 10 billion light-years away. The galactic grouping, discovered by NASA's Spitzer Space Telescope, was observed when the universe was roughly a quarter of its current age of 13.7 billion years.

Scientists studying images from NASA's Cassini spacecraft have found that heat from within the planet powers the jet streams.

Lichen is an example that was exposed to space conditions on the International Space Station for 18 months. Some lichens survived the ordeal and continued to grow in the laboratory. Several trays filled with organisms were installed on the outside of the European Columbus laboratory.
