Large bombardments of meteorites approximately four billion years ago could have helped to make the early Earth and Mars more habitable for life by modifying their atmospheres, suggests the results of a paper published today in the journal Geochimica et Cosmochimica Acta. When a meteorite enters a planet's atmosphere, extreme heat causes some of the minerals and organic matter on its outer crust to be released as water and carbon dioxide before it breaks up and hits the ground. Researchers...

A U.S. space agency-funded study suggests an intense asteroid bombardment nearly 4 billion years ago might have provided a boost for early life on Earth. The National Aeronautics and Space Administration said the research suggests the asteroids might not have sterilized the early Earth as completely as previously thought. The study focused on a particularly cataclysmic occurrence known as the Late Heavy Bombardment, or LHB, NASA said. This event occurred approximately 3.9 billion years ago...

The bombardment of Earth nearly 4 billion years ago by asteroids as large as Kansas would not have had the firepower to extinguish potential early life on the planet and may even have given it a boost, says a new University of Colorado at Boulder study. Impact evidence from lunar samples, meteorites and the pockmarked surfaces of the inner planets paints a picture of a violent environment in the solar system during the Hadean Eon 4.5 to 3.8 billion years ago, particularly through a...

Meteorites provide valuable information about the early history of the solar system. A group of Swiss geologists have conducted systematic meteorite searches in Oman since 2001, and they recently returned from their latest hunt.Most meteorites are fragments of asteroids, some of which contain organic matter. Some meteorites preserve information on the chemical make-up of the solar system before the planets formed. Other meteorites are impact debris from the surfaces of the Moon and Mars....

Radiation and the sun's rays help dust on the surface of the moon obtain its noted stickiness, an Australian scientist says. Brian O'Brien, who helped with the United States' Apollo space program during the 1960s, said his research indicates lunar dust becomes sticky after being exposed to a combination of X-ray radiation and the sun's ultraviolet rays, the Los Angeles Times said Thursday. The degree of stickiness for the dust can be increased by the level of exposure to the sun's rays,...

In the 1960s and 1970s, the Apollo Moon Program struggled with a minuscule, yet formidable enemy: sticky lunar dust. Four decades later, a new study reveals that forces compelling lunar dust to cling to surfaces "” ruining scientific experiments and endangering astronauts' health "”change during the lunar day with the elevation of the sun. The study analyzes the interactions on the Moon among electrostatic adhesive forces, the angle of incidence of the sun's rays, and lunar...

An Australian-led study shows, for the first time, differences in light reflection from Earth's land masses and oceans can be seen on the moon's far side. The researchers, led by Sally Langford of the University of Melbourne and including scientists from Princeton University, said the phenomenon, known as earthshine, might be used to view the physical makeup of planets too small to allow an image to be made of their surface. Langford said the brightness of the reflected earthshine varied as...

China's seismological network says the country's northern region was rattled by a 4.2-magnitude earthquake Saturday. China's state-run news agency, Xinhua, reported the quake in Shanxi province had not resulted in any reported casualties or damages. The seismological network said the quake that rocked Yuanping City was detected at a depth of 3.1 miles at 38.9 degrees north latitude and 112.9 degrees east longitude.

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...
