Above the Clouds
23.04.2008

From the windswept peak of Mauna Kea, on the Big Island of Hawaii, your view of the world at night could look like this. At an altitude of about 13,500 feet, the mountain top is silhouetted in the stunning skyscape recorded near dusk in early December of 2005.

Moon and Morning Star
24.04.2009

Wednesday, the Moon and Venus rose together in early morning skies. Even through clouds, both show off a lovely crescent in this well-composed skyscape from Rutherford College, North Carolina, in the eastern US. Farther west, North American skygazers could also witness the Moon passing in front of Venus.

Moonquakes Surprisingly Common
27.03.2006

Why are there so many moonquakes? A recent reanalysis of seismometers left on the moon by the Apollo moon landings has revealed a surprising number of moonquakes occurring within 30 kilometers of the surface. In fact, 28 moonquakes were detected in data recorded between 1972 and 1977.

Standing on the Moon
3.05.1998

Humans once walked on the Moon. Pictured above is the second person to stand on the lunar surface: Edwin "Buzz" Aldrin. During this Apollo 11 mission, Neil Armstrong (the first person to walk on the moon) and Buzz Aldrin landed on the Moon while Michael Collins circled in the Command Module above.

Lunar Diamond
6.12.2008

Cameras around the globe pointed skyward this week to capture the spectacular conjunction of a crescent Moon and bright planets Venus and Jupiter. But astronomer-artist Deirdre Kelleghan recorded her observations in sketches of the celestial event.

Target Crater Cabeus
8.10.2009

About 100 kilometers from the Moon's South Pole, 100 kilometer wide crater Cabeus is the target for two LCROSS mission spacecraft on course to impact the Moon tomorrow. The shadowed crater is strongly foreshortened in this mosaic, a representative view of the region for earthbound telescopes.

Messier Craters in Stereo
11.12.2009

Many bright nebulae and star clusters in planet Earth's sky are associated with the name of astronomer Charles Messier, from his famous 18th century catalog. His name is also given to these two large and remarkable craters on the Moon.

Total Lunar Eclipse Tonight
27.10.2004

Go outside tonight and see the total lunar eclipse. Tonight's eclipse is easy and convenient for much of the world to see. Anyone who can spot a full Moon -- even during the day -- can see it fade out as the Earth's shadow engulfs it.

A Time Lapse Lunar Eclipse
3.11.2004

During last week's lunar eclipse, our Moon appeared to disappear. As the Earth moved between the Moon and the Sun, the Earth's shadow fell on the moon, making it quite dark.

The Iron Moon
1.06.1996

In March and April of 1994 the unmanned Clementine spacecraft demonstrated the technique of prospecting on the Moon from lunar orbit. To accomplish this, Clementine turned an array of cameras sensitive to ultraviolet-visible and near-infrared light toward the lunar surface, producing the first broad-spectrum global imaging of the moon.
