NASA's bold asteroid-capture mission may not end when astronauts leave the space rock for the last time. Seeing it through could require disposing of the asteroid in a safe — and possibly very dramatic — manner, experts say.

Is the moon a present from Venus, which once had a moon and then lost it? A wild new theory puts the scenario out there.
26 September 2013, 01:46 PM ET
As the Moon passes through Earth's magnetic field, two lunar-orbiting spacecraft look for turbulence, particle acceleration, and magnetic reconnection. These phenomena control how the solar wind interacts with Earth's magnetosphere.
23 September 2013, 06:00 AM ET
The leading theory of the moon's origin holds that it was created when a mysterious planet slammed into Earth about 4.56 billion years ago. But new analyses of lunar rocks suggest that the moon is actually between 4.4 billion and 4.45 billion years old.

A small asteroid harmlessly zipped by Earth closer than the orbit of the moon today (Sept. 18). At just 3 to 10 feet in diameter, asteroid 2013 RZ53 would have burned up in Earth's atmosphere if it were on a collision course with the planet.

Tonight's full moon is called the Harvest Moon because many fruits and vegetables tend to ripen in the late summer and early fall. Farmers once relied on this full moon's light, working late into the evening to harvest their crops.

A small asteroid first discovered last Friday will whiz by the Earth today (Sept. 18), zipping closer than the orbit of the moon. The space rock poses no danger to Earth, scientists say.
16 September 2013, 05:34 PM ET
A tiny asteroid discovered just last week is set to zip by Earth on Wednesday (Sept. 18), passing between our planet and the moon. It is small enough and distant enough that it poses no threat to people.
