NRAO's Ground-based Radio Telescopes to be Used With NASA's GLAST Gamma-Ray Satellite
NASA's Gamma-ray Large Area Space Telescope (GLAST) is scheduled for launch early next year. The National Radio Astronomy Observatory (NRAO) is teaming with NASA so that astronomers can conduct coordinated observations using the orbiting satellite and the ground-based radio telescopes simultaneously to maximize their scientific value.
Spitzer Gives Scientists Depth Perception
Astronomers now have a new method for determining the distance to certain mysterious bodies in and around our Milky Way galaxy. By taking advantage of the unique position of the NASA Spitzer Space Telescope about 40 millions miles from Earth, and a depth-perceiving technique called parallax, they are now able to pin down the location of dark matter object in and aroung our galaxy. Once this technique is perfected, astronomers will be able to more accurately measure the distances to these dark matter objects.
NASA Dedicates Flying Observatory on Lindbergh 80th Anniversary
SOFIA is a Boeing 747SP extensively modified to carry a 45,000-pound (20 metric ton), 98.4-inch (2.5-meter) diameter infrared telescope assembly. SOFIA will fly at altitudes up to 45,000 feet (13.7 km) - above more than 99 percent of the Earth's water vapor - to capture infrared images and spectra not possible by even the largest ground-based telescopes. On Monday, May 21, 2007, NASA dedicated a unique astronomy aircraft to pioneering aviator Charles Lindbergh on the 80th anniversary of his historic transatlantic flight.
Hubble Turns Seventeen - Now Old Enough to Drive
In its 17 years of exploring the heavens, NASA's Hubble Space Telescope has made nearly 800,000 observations and snapped nearly 500,000 images of more than 25,000 celestial objects. In its 17-year lifetime, the telescope has made nearly 100,000 trips around our planet, racking up about 2.4 billion miles. The 17 years' worth of observations has produced more than 30 terabytes of data, equal to about 25 percent of the information stored in the Library of Congress. Astronomers using Hubble data have published nearly 7,000 scientific papers, making it one of the most productive scientific instruments ever built.
NASA's Chandra Verifies Discovery of Brightest SuperNova Ever
According to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes, SuperNova SN 2006gy is the brightest and most energetic stellar explosion ever recorded and may be a long-sought new type of explosion. The Chandra observation allowed astronomers to determine that SN 2006gy was indeed caused by the collapse of an extremely massive star, and not the most likely alternative explanation for the explosion, the destruction of a low-mass star.
Walter Schirra, Apollo 7 Astronaut, Dies at 84
SAN DIEGO (AP) -- Astronaut Walter M. "Wally" Schirra Jr., one of the original Mercury Seven astronauts and the only man to fly on all three of NASA's early space missions, has died, a NASA official confirmed Thursday. He was 84.
