Latest Lunar science Stories
Hundreds of moon rocks that have been handed out to state governments and foreign countries through the years have gone missing, according to a NASA audit last December. Though some have been recovered, most are still missing.
MESSENGER, in orbit around Mercury since March of last year, has discovered assemblages of tectonic landforms unlike any previously found on Mercury or elsewhere in the Solar System.
Researchers are saying the massive dark spot seen on the moon, known as the Ocean of Storms, is a scar from a giant cosmic impact.
European researchers are in the process of building an unmanned probe that would travel to the moon, where it would search for subsurface ice on the lunar surface, within the next six years.
Scientists are backing up a theory, claiming that the Moon was created when a planetary body the size of Mars collided with Earth.
Water molecules discovered in soil samples collected from the moon could have indirectly originated from the sun, claim the authors of a new study published Sunday in the journal Nature Geoscience.
Astronomers suggest that water may have been delivered to Vesta through a build-up of small particles during an epoch when the Solar System was rich in dust.
Around 4.5 billion years ago, the Earth is believed to have collided with an impactor the size of Mars known as "Theia." This collision, current theory says, is what formed the Moon.
Using the LAMP spectrometer aboard NASA's Lunar Reconnaissance Orbiter, scientists have made the first spectroscopic observations of the noble gas helium in the atmosphere surrounding the Moon.
The Hadean is the unofficial geological period of time that lies just before the Archean time period. The Hadean began with the formation of the Earth roughly 4.5 billion years ago (Ga) and ended about 3.8 Ga; the latter date varies according to different sources. Hadean is derived from Hades, Greek for “underworld,” referring to the hellish conditions on the planet at the time. The term was coined in 1972 by geologist Preston Cloud. The period was later classified as the “Priscoan...
Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...
The Moon -- The Moon is the largest satellite of the Earth, and is occasionally called Luna (Latin for moon) to distinguish it from the general use of the word "moon". The Moon is distinguished from the satellites of other planets by its initial capital letter; the other moons are described in the natural satellite article. The words moon and month come from the same Old English root word. The Moon makes a complete orbit of the celestial sphere about every four weeks. Each hour the...
The Moon -- natural satellite of a planet, in particular, the single natural satellite of the earth. The Earth-Moon System The moon is the earth's nearest neighbor in space. In addition to its proximity, the moon is also exceptional in that it is quite massive compared to the earth itself, the ratio of their masses being far larger than the similar ratios of other natural satellites to the planets they orbit (with the exception of Charon and Pluto). For this reason, the...
