Sun Darkens Electronics
Solar activity can wreak
havoc in communications
systems -- particularly
during coronal mass
ejections, when plumes of
electrically charged
particles hit earth's

Spotting Sun Spots
Sun spots are cooler regions
on the sun's surface held up
by magnetic fields, and they
can have dramatic effects on
space weather, disrupting
satellite communications.
Astrophysicists track them
with sophisticated tools,

Lunar Eclipse
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 perfectly

Are Saturn's Rings Disappearing?
Astronomers say that
Saturn's rings will
disappear from view on Earth
on September 4, 2009. The
gases, ice, and rocky
material that make up the
rings will remain in place,

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 -
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 -
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 -
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 -
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 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 -
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 -
Planetary Scientists To Find Out Composition, Structure Of Asteroids
A NASA mission to two asteroids, one formed of lava and the other potentially containing water, will help find clues about the formation of our solar ... > 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 -
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
