Tracking Pollution From Space
Engineers processed data
from NASA's Aura satellite
in order to track and
predict the movement of
airborne pollution. Using
satellite data to measure
ozone concentrations over

Preparing For A Walk On The Moon
Astrophysicists found that
the moon's surface becomes
electrified during each full
moon. The moon passes
through the Earth's
magnetotail, a cone of
highly-charged particles,

Unlocking The Mystery Of The Moon
Astrophysicists used the
Spitzer Space Telescope to
scan a cluster of about 500
stars for evidence of a
collision similar to the one
that produced Earth's moon.
The telescope searches in

Moon Rover
Engineers and robiticists
created a robot to explore
the moon. Running on the
same amount of power as a
100-watt light bulb the
rover uses heat from
radiation to support its
sensors, movement, and

Astronomers And Computer Scientists Reveal Astronomical Events In Real Time
Astronomers have added an application to Google Earth that allows users to not only look at detailed pictures of the night sky at their convenience, but to observe unfolding cosmic events in real ... > more -
Total Lunar Eclipse Casts Eerie Red And Orange Glow
A total lunar eclipse was observed during the summer of 2007. A total lunar eclipse occurs when a full moon passes through the earth's shadow during its orbit. When the sun, Earth and moon are ... > more -
Astronomers Reveal First Objects In Our Universe
Astronomers removed light from closer and better known galaxies and stars from pictures taken with the Spitzer Space Telescope. The remaining images are believed to be the first objects in space, 13 ... > more -
Acoustic Waves Could Help Put Out Flames in Zero-Gravity Environments
Aboard NASA's "Weightless Wonder" airplane, physicists are experimenting with combustion and fluid flows in zero-g and developing a fire extinguishing system based on sound waves. The technique could ... > more -
Astronomers Spot Black Holes Using NASA's Chandra X-Ray Observatory
Not even light can escape a black hole's grip, but gas falling into a black hole can heat up and become an intense source of X-rays, at temperatures up to 1,000 times hotter than the sun. Astronomers ... > more -
Physicists Spot Interstellar Shock Wave Using Spitzer Telescope
The spirals of a "space tornado" may be the first step in the formation of a new star. The structure, observed with NASA's Spitzer infrared telescope, is a shock wave created by a jet of material ... > more -
Microbiologists and Astrobiologists Help Kids Discover New Species
Extremophiles are microbes that have adapted to extreme environments, such as Utah's Great Salt Lake. But new microorganisms can be found in everyday places, and scientists are showing school kids ... > more -
Planetary Scientists Use Hubble to Spot Oxygen-Rich Soil on Moon
The Moon's surface is covered with oxygen-rich soils, Hubble Space Telescope images show. Planetary scientists believe the oxygen could be tapped to power rockets and be a source of oxygen to breathe ... > more
