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

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

A Blue Moon Month
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 side of the earth,

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

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 -
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 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 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 -
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 -
