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

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

Unlocking The Mystery Of The Moon
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

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

Astronomers Discover That The Earth's Magnetotail Charges The Surface Of 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, for about 6 days each ... > 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 -
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 -
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 -
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 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 -
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 -
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
