Relatively few galaxies possess the sweeping, luminous spiral arms or brightly glowing center of our home galaxy the Milky Way.

This is an image taken from one of NASA’s two special "Webb-cams,” a camera in a giant clean room at NASA Goddard. The Webb-cams focus on what's happening with the very first completed instrument that will fly onboard the James Webb Space Telescope. The flight Integrated Science Instrument Module (ISIM) is at left center. The Ambient Optical Assembly Stand is on the right side of the image.

The Soyuz TMA-03M capsule with astronauts Don Pettit, Oleg Kononenko and ESA astronaut André Kuipers touchdown on Sunday 1 July 2012 at 08:14 GMT. They landed in the steppes of Kazakhstan after 193 days in space.

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.
