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,

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

Blimps in Space
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 place for

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 -
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 -
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 -
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 -
Astronomers Need Your Help To Find Planets Outside Our Solar System
A new distributed computing program analyzes data to characterize new planetary systems by computing the light reflected from nearby extrasolar planets and the wobble the planets cause in their stars ... > more -
Astrophysicists Discover New Details of How Stars Collapse
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 and ... > 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 -
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
