Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

redOrbit Staff & Wire Reports - Your Universe Online Using new data obtained by the MESSENGER spacecraft, researchers from Brown University in Rhode Island have discovered that explosive volcanic activity has been occurring throughout most of Mercury’s history, meaning that the planet has had the volatile compounds necessary for those eruptions for longer than anticipated. The findings, which are detailed in a recent edition of the Journal of Geophysical Research: Planets, are...

Moon-Forming Impact Dated

redOrbit Staff & Wire Reports - Your Universe Online Using a new method for estimating the moon’s age, an international team of planetary scientists has determined that the satellite formed nearly 100 million years after the formation of the solar system, according to research published Thursday in the journal Nature. The study authors came to that conclusion based on measurements from the Earth’s interior, as well as computer simulations of the protoplanetary disk from which...

April Flowers for redOrbit.com - Your Universe Online Scientists studying the mineral apatite may have overestimated the amount of water present in the moon, according to a new study led by the University of California Los Angeles (UCLA) Department of Earth, Planetary and Space Sciences. In order to accurately predict how apatite would have crystallized from cooling bodies of lunar magma early in the moon's history, Jeremy Boyce led a team of researchers to develop a new computer model....

NASA's LADEE Sends Its First Lunar Images Back To Earth
2014-02-14 11:28:42

Lee Rannals for redOrbit.com - Your Universe Online NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) observatory has sent its first images of the moon back to Earth. LADEE uses its star tracker instrument to help calibrate itself and determine its orientation in space. These images represent the first time that NASA officials have commanded LADEE to send images back to Earth. "Star tracker cameras are actually not very good at taking ordinary images," Butler Hine, LADEE...

Lunar Eclipse Makes Laser Ranging More Accurate

April Flowers for redOrbit.com - Your Universe Online The full moon has long been linked to strange events and even stranger behavior, even though careful scrutiny has dispelled any association, according to Susan Brown of UC San Diego. So when scientists bounced signals off the lunar surface on full moon nights and only received faint echoes in return, they went looking for an explanation based in reason, not superstition. The most compelling evidence, though, arrived during another event...

John Lennon Shines On: IAU Names Mercury Crater After Rock Legend
2013-12-20 13:34:02

Gerard LeBlond for redorbit.com - Your Universe Online John Lennon was born on October 9, 1940 in Liverpool, England. He started his first band, The Quarrymen, while still in high school. After Paul McCartney and George Harrison joined the band the name was changed to The Beatles. He and his band mates became rock legends, but John met a tragic end on December 8, 1980. Now Lennon, along with nine other notable celebrities of the past, have been honored by having impact craters on...

Lunar Impact Crater Has A Diverse Subsurface Mineralogy

redOrbit Staff & Wire Reports - Your Universe Online The presence of a diverse group of minerals in the largest lunar impact crater could help scientists gain new insight into the Moon’s interior, as well as the evolution of its crust and mantle, claims new research appearing online in Journal of Geophysical Research: Planets. Dan Moriarty, a graduate student from Brown University, and his colleagues analyzed data collected from the Moon Mineralogy Mapper instrument aboard India's...

Chesapeake Bay Impact Crater Is Home To Oldest Seawater On Earth

[ Watch the Video: Old Water Found In The New World ] redOrbit Staff & Wire Reports - Your Universe Online US Geological Survey (USGS) hydrologists drilling into the largest crater in the country have stumbled across an amazing discovery – the oldest body of seawater ever unearthed. The water, which according to Discovery News is at least 100 million years old, was found over one kilometer beneath Chesapeake Bay in Virginia. The seawater is believed to have come from the...

Apollo Data On Lunar Dust
2013-11-21 04:12:52

April Flowers for redOrbit.com - Your Universe Online In 1969, Neil Armstrong took man's first otherworldly steps onto the lunar surface. He had no idea what a nuisance the soil beneath his feet would prove to be at the time. Scratchy lunar dust clung to everything it touched. This caused scientific instruments to overheat and a type of lunar dust hay fever for Apollo 17 Astronaut Harrison Schmitt. NASA undertook a scientific experiment to figure out how fast the dust collects, but the...

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...
