Fighting Fire with Sound
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

Ultrasounds: From Space to Sports
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,

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,

First Stars In The 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

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 -
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 -
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 -
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 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 -
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 -
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 Discover Eight New Gravitational Lenses with Hubble Telescope
Images from the Hubble telescope reveal eight new Einstein rings, joining only three others previously known. Einstein rings are pairs of galaxies, with a foreground galaxy bending the light of a ... > 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
