Lunar Eclipse
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 perfectly

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

Back to the 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

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,

Astronomers Explain Science Behind Folk Saying
A blue moon is when two full moons occur within the same month, as dictated by the satellite's 29.5 day orbit around the earth. A full moon is that point in the moon's orbit when it's on the back ... > more -
Astrophysicists Search Skies For A Moon Like Earth's
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 the infrared ... > more -
Astronomers Explain New Double Star In Western Sky
Astronomers say that this July planetary orbits have lined up so that people on Earth can see a rare convergence of Venus and Saturn in the night sky. Just after sunset they will appear in the west, ... > more -
Astronomers Look At Ultraviolet Light To Find Star’s Tail
Astronomers found a tail of carbon, oxygen, and other material trailing behind a dying star called Mira. People have watched the star break down for 400 years, but only recently have astronomers ... > more -
Astronomers Spy Earth-like Planet Forming Around Distant Star
Astrophysicists analyzing infrared images captured by the Spitzer Space Telescope found indications of a dust cloud surrounding a relatively young star. The star is 10 to 16 million years old, and ... > more -
Astronomers Explain Reason For Narrowing Rings Of Saturn
Astronomers say that Saturn's rings will disappear from view on Earth on September 4, 2009. The gases, ice, and rocky material that make up the rings will remain in place, but be invisible from the ... > more -
Mechanical And Aerospace Engineers Use Satellites To Track Ozone Levels
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 time allows scientists ... > more -
Mechanical Engineering Students Develop High-Altitude Reconnaissance Airships
On a shoestring, and with off-the-shelf components, students are designing prototypes of robotic blimp that could one day be used by the Pentagon. Cheaper than spy satellites, blimps can hover in ... > more -
Planetary Scientists To Find Out Composition, Structure Of Asteroids
A NASA mission to two asteroids, one formed of lava and the other potentially containing water, will help find clues about the formation of our solar ... > 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
