Searching For Extrasolar Planets
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

Finding Double Stars
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, looking

Visit To An Asteroid
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 system. ... > full story
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

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 -
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 -
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 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 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 -
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 -
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 -
With Precautions, Anyone Can Observe the Sun Safely
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 ... > 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
