Earth's Moon: Formation, Composition and Orbit
Scientists say a giant impact knocked off the raw ingredients for the moon off the primitive molten Earth and into orbit.
The Republican front-runner said he's proud of the idea.
After today, skywatchers will have to wait until 2014 for the next total lunar eclipse.
An instrument aboard the Lunar Reconnaissance Orbiter (LRO) will gauge temperatures on the moon while it's in the Earth's shadow on December 10th, 2011. Size and density of rocks can be extrapolated from the results.
Intense solar storms can strip material off the surface of the moon like a sandblaster, a new study finds.
This partial eclipse was the first of four to occur in 2011 and it’s rare to see so many within the same year.
What makes the moon turn dark and red? Find out in this SPACE.com infographic.
Researchers are proposing that floating lunar dust grains are ionized by UV rays from the Sun to create the Moon's ionosphere. An ionosphere composed of dust instead of gas is a new frontier for science, one that NASA probes are set to study.
Today's partial solar eclipse was the fourth and final one this year.
For more than 50 years, NASA's robotic deep space probes have carried nuclear batteries provided by the U.S. Department of Energy. Even the crewed Apollo moon landings carried nuclear powered equipment.
A celestial triangle made up of the moon, Mars and Regulus can be seen in the sky early Saturday morning.
The new topographic view maps the moon with a resolution of 330 feet per pixel.
Bright moonlight could outshine even the brightest meteors this year.
Moon Express co-founder Naveen Jain chats with SPACE.com about our planet's natural satellite.
NASA's Space Launch Systems upper stage J-2X rocket engine was successfully test fired for 500 seconds on November 9th, 2011.
Earth and Planetary Science Professor Randy L. Korotev of Washington University in St. Louis examines meteorites from different celestial bodies and talks about what makes one more valuable than the other.
John Chumack (www.galacticimages.com) captured these images of the space rock's Earth fly-by in Yellow Springs, Ohio. The asteroid was about 201,700 miles away and was passing between the Moon and Earth.
Asteroid 2005 YU55 will fly an estimated 201,700 miles from Earth at its closest point (Nov. 8th & 9th). Radio antennas pointed towards the 1300-foot-wide space rock will provide scientists with imagery resolution of up to 7 feet per pixel.
The Orionids aren't the only interesting objects in the sky this week.
