Visit To An Asteroid
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 system. ... > full story
The Mystery of Black Holes
A satellite called Swift is
revealing that black holes
have a messier birth than
previously thought. Instead
of being created in one
instant, astrophysicists now
believe after a star dies
... > full story
Space Tornado
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 slamming on a

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

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 -
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 -
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 -
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 -
Space Physicists and Atmospheric Scientists Can Now Predict Disruptions Caused by the Sun's Coronal Mass Ejections
Solar activity can wreak havoc in communications systems -- particularly during coronal mass ejections, when plumes of electrically charged particles hit earth's atmosphere. Scientists can now track ... > 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 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 -
With Precautions, Anyone Can Observe the Sun Safely
Sun spots are cooler regions on the sun's surface held up by magnetic fields, and they can have dramatic effects on space weather, disrupting satellite communications. Astrophysicists track them with ... > 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 -
Portable Machines Go Beyond Prenatal Uses
Ultrasound uses sound waves that bounce off body parts, producing echoes. A computer translates the echoes into images that rival the quality of CAT scans and MRIs, showing broken bones, muscle ... > more
