Space Shuttle Endeavour Astronaut Mae Jemison works in the Spacelab-J module, inside the space shuttle. Spacelab-J is a combined National Space Development Agency of Japan (NASDA) and NASA. The objectives included life sciences, microgravity and technology research. NASA
The Lunar Roving Vehicle gets a speed workout by astronaut John W. Young in the 'Grand Prix' run during the third Apollo 16 Extravehicular Activity at the Descartes landing site. This view is a frame from motion picture film exposed by a 16mm Maurer camera held by astronaut Charles M. Duke, Jr. While astronaut's Young, commander, and Duke, lunar module pilot, descended in the Lunar Module 'Orion' to explore the Descartes highlands region of the Moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules 'Casper' in lunar orbit. NASA
This is a unique view of the disk galaxy NGC 5866 tilted nearly edge-on to our line-of-sight. Hubble's sharp vision reveals a crisp dust lane dividing the galaxy into two halves. The image highlights the galaxy's structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo. NGC 5866 is a disk galaxy of type 'S0' (pronounced s-zero). Viewed face on, it would look like a smooth, flat disk with little spiral structure. NASA/ESA/The Hubble Heritage Team/STScI/AURA
The pale blue Earth serves as backdrop for astronaut Michael Gernhardt during his Extravehicular Activity. He is standing on a Manipulator Foot Restraint attached to the Remote Manipulator System. He is positioned over the Payload Bay and Endeavour's forward section is reflected in his visor. NASA
Kepler's Supernova Remnant is seen in this Hubble image. The exploding star was the last supernova to have been observed in the Milky Way, for the first time in 1604. NASA/ESA/The Hubble Heritage Team/STScI/AURA
The Extra Vehicular Activity Exercise Device for evaluation and effectiveness of weightlessness on astronauts during long duration spaceflights is seen at the NASA Ames Research Center, Mountain View, California. NASA
Astronaut Alan L. Bean, Skylab 3 commander, flies the M509 Astronaut Maneuvering Equipment, as seen in this photographic reproduction taken from a television transmission made by a color television camera in the Orbital Workshop of the Skylab space station in Earth orbit. Skylab orbited the Earth from 1973 to 1979, and was visited by Astronauts only three times in 1973 and 1974. NASA
NASA's Hubble Space Telescope snapped a view of what may be the youngest galaxy ever seen. This 'late bloomer' may not have begun active star formation until about 13 billion years after the Big Bang. Called I Zwicky 18 (below, left), the galaxy may be as young as 500 million years old. This youngster has gone though several sudden bursts of star formation - the first only some 500 million years ago and the latest only 4 million years ago. NASA/ESA/Y. Izotov/T. Thuan
In its 15 years of viewing the sky, NASA's Hubble Space Telescope has taken more than 700,000 exposures and probed more than 22,000 celestial targets as represented by the different colored dots in this map of the sky. All data from April 1990 through March 2005 are represented here. Solar system objects are shown as yellow dots; stars are blue; star clusters are orange; nebulae are green; galaxies are red; galaxy clusters are pink; and other targets such as the Hubble Ultra Deep Field and the Great Observatories Origins Deep Survey are the white dots.
