Viewers throughout most of the United States are in position to see a partial solar eclipse Thursday afternoon (Oct. 23). Unfortunately, clouds will likely get in the way in some parts of the country.
22 October 2014, 07:00 AM ET
The unmanned mission will apparently send a spacecraft around the moon; on its way back toward Earth, the probe will release a capsule to perform a high-speed plunge through the planet's atmosphere.

There's a certain irony to the observation that Tom Hanks today may be better known for flying to the moon than Alan Bean, who actually went there. The actor and director celebrates Bean and laments his anonymity in the pages of "The New Yorker."
20 October 2014, 09:48 AM ET
Warning: Do not look directly at the Sun. On October 23rd, 2014, most of the North America will be treated to the eclipse. Viewing from the eastern U.S. will be especially beautiful, weather permitting, due to it occurring at the end of the day.
20 October 2014, 06:01 AM ET
Nearly all of North America will experience the solar eclipse. People who live east of a line running from roughly Quebec City to Montauk Point, New York, will miss out, since the sun will set before the dark disc of the moon begins to encroach upon it.

Without proper regulation, the moon risks becoming an extra-planetary Wild West.

Last week's lunar eclipse wasn't just a show for Earthlings, NASA's MESSENGER mission was also watching from Mercury, 66 million miles away.
17 October 2014, 07:30 AM ET
Forty-six years ago this week, NASA's first Apollo astronauts to launch into space were circling the Earth, just as the crew's mission patch depicted. The official insignia though, was not what the crew initially envisioned as representing their flight.
15 October 2014, 05:54 PM ET
The images, taken by NASA's MESSENGER spacecraft, suggest that the ice lurking within Mercury's polar craters was delivered recently, and may even be topped up by processes that continue today, researchers said.
14 October 2014, 07:37 AM ET
Scientists previously thought that the moon's volcanic activity died down a billion years ago. But new data from NASA's Lunar Reconnaissance Orbiter, or LRO, hints that lunar lava flowed much more recently, perhaps less than 100 million years ago.
14 October 2014, 07:00 AM ET
The upcoming launch, expected to take place Oct. 23 from China's Xichang Satellite Launch Center, will apparently send an experimental, recoverable probe to lunar orbit and back to validate tech needed for a lunar sample-return mission.
10 October 2014, 08:01 AM ET
The moon, the famous Pleiades star cluster and the red star Aldebaran will dance together in the night sky this Saturday.
09 October 2014, 07:00 AM ET
Space agency scientists are developing two separate mission concepts, called Lunar Flashlight and the Resource Prospector Mission, to assess, and learn how to exploit, stores of water ice and other lunar resources. Both would launch by 2018.

An architect with an interest in spaceflight has drafted a design to relaunch the display of a Saturn V moon rocket in Houston. Brantley Hightower's idea for a glass-fronted building came after he visited the booster at NASA's Johnson Space Center.

Amateur astronomer Victor Rogus talks about his experiences observing total lunar eclipses.
03 October 2014, 04:37 PM ET

26 September 2014, 07:00 AM ET
Currently the constellation Libra is host to the planet Saturn and two of the largest and brightest asteroids, Ceres and Vesta. In addition, the crescent moon will be passing through on its monthly trip around the Earth.
23 September 2014, 10:49 AM ET
NASA's New Horizons spacecraft may still be 10 months from its historic flyby with dwarf planet Pluto, but it is making good use of its interplanetary cruise to get familiar with its flyby target by imaging Pluto's outermost moon Hydra
