In this image of the Andes along the Chile-Bolivia border, the visible and infrared data have been computer enhanced to exaggerate the color differences of the different materials. The scene is dominated by the Pampa Luxsar lava complex, occupying the upper right two-thirds of the scene. Lava flows are distributed around remnants of large dissected cones, the largest of which is Cerro Luxsar. NASA/GSFC/METI/ERSDA C/JAROS, and U.S./Japan ASTER Science Team/JPL
Astronomers using NASA's Hubble Space Telescope have found a bow shock around a very young star in the nearby Orion nebula, an intense star-forming region of gas and dust. It was taken in February 1995 as part of the Hubble Orion Nebula mosaic by Hubble's Wide Field and Planetary Camera 2, designed and built by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA and the Hubble Heritage Team (STScI/AURA)
Apollo 12 astronaut Alan Bean holds a special environmental sample container filled with lunar soil collected during his sojourn on the lunar surface. A Hasselblad camera is mounted on the chest of his spacesuit. Pete Conrad, who took this image, is reflected in Bean's helmet visor, on Nov. 20, 1969. NASA
The two bright sources at the center of this composite x-ray image are co-orbiting supermassive black holes powering the giant radio source. Surrounded by multimillion degree x-ray emitting gas, and blasting out jets of relativistic particles, the supermassive black holes are separated by 25,000 light-years. At the cores of two merging galaxies in the Abell 400 galaxy cluster they are some 300 million light-years away. NASA/CXC/D.Hudson, T.Reiprich et al./AIfA/NRAO/VLA/NRL

This is a rare view of Saturn's rings seen just after the Sun has set below the ring plane. This perspective is unusual because the Earth is slightly above Saturn's rings and the Sun is below them. Normally we see the rings fully illuminated by the Sun. The low concentration of material in these rings allows light from the Sun to shine through them.

This photo is the world's first view of Earth taken by a spacecraft from the vicinity of the Moon. The photo was transmitted to Earth by the United States Lunar Orbiter I and received at the NASA tracking station at Robledo De Chavela near Madrid, Spain. This crescent of the Earth was photographed August 23, 1966. NASA
A piece of NASA history landed at the Glenn Research Center's Visitor Center, now located at the Great Lakes Science Center in Cleveland, Ohio. The Apollo Command Module, used for the Skylab 3 mission in 1973, was moved successfully from Glenn to the Science Center. The module will be the focal point of the Visitor Center, which includes space and aeronautics artifacts, models and interactive experiences. NASA

The attack took place at the same intersection where a Palestinian man rammed his car into a crowded train platform in November.

A Palestinian assailant rammed his car into a group of Israeli pedestrians near an Israeli police station in east Jerusalem on Friday, injuring four officers and a bystander, and lunged at security guards with a knife before being shot and wounded, the police said.
