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

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

Black Holes Light Up
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 use the Chandra

Einstein Rings
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 background

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 -
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 -
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 -
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 -
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 -
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 -
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 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
