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

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

Discovering A New Earth 430 Light Years Away
Astrophysicists analyzing
infrared images captured by
the Spitzer Space Telescope
found indications of a dust
cloud surrounding a
relatively young star. The

Back to the 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

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 -
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 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 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 -
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 -
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 -
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 -
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 -
Roboticists Create Rover To Move And Drill On The Moon
Engineers and robiticists created a robot to explore the moon. Running on the same amount of power as a 100-watt light bulb the rover uses heat from radiation to support its sensors, movement, and ... > more -
Astronomers Look At Ultraviolet Light To Find Star’s Tail
Astronomers found a tail of carbon, oxygen, and other material trailing behind a dying star called Mira. People have watched the star break down for 400 years, but only recently have astronomers ... > more
