Spitzer finds black widow nebula hiding in the dust NASA/JPL PHOTO RELEASE Posted: October 29, 2005
When individual stars form from molecular clouds of gas and dust they produce intense radiation and very strong particle winds. Both the radiation and the stellar winds blow the dust outward from the star creating a cavity or, bubble. In the case of the Black Widow Nebula, astronomers suspect that a large cloud of gas and dust condensed to create multiple clusters of massive star formation. The combined winds from these groups of large stars probably blew out bubbles into the direction of least resistance, forming a double bubble. The infrared image was captured by the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) Legacy project. The Spitzer picture is a four-channel false-color composite, showing emission from wavelengths of 3.6 microns (blue), 4.5 microns (green), 5.8 microns (orange) and 8.0 microns (red). |

For the first time since Hurricane Katrina, NASA's Stennis Space Center in Mississippi conducts a test-firing of a space shuttle main engine. The engine was run as part of a certification series on the Advanced Health Management System, which monitors engine performance.
Edwards Air Force Base hosted an open house and air show this past weekend. NASA's Dryden Flight Research Center demonstrated some of its specialized aircraft -- a highly modified NF-15B, a high-altitude ER-2, and F/A-18 and T-34. On the ground, a variety of specialized air and space vehicles were on display in the NASA exhibit, ranging from the Mars rovers to the 747 space shuttle carrier aircraft.
Scientists eagerly examine suitcase-like packages, called the Materials International Space Station Experiments, or MISSEs, after return to Earth. The MISSE packages were flown outside the orbiting station to expose different materials to the space environments for study.
This 2005 Atlantic hurricane season has a been a record-breaker. Satellite imagery since June 1 has been compiled into this movie to track the 21 named storms as they formed and traveled, many making landfall.
International Space Station cameras captured this incredible video of Hurricane Wilma and its well-defined eye from an altitude of 220 miles. Wilma was packing winds of 175 miles an hour as a Category 5 storm when the station flew overhead.
NASA has used the Hubble Space Telescope for scientific observations of the Earth's moon in the search for important oxygen-bearing minerals -- potential resources for human exploration. Scientists held this news conference on October 19 to discuss their investigations.
