A New Russian Meteorite?
On Thursday 3 October, residents of the village of Bodaibo in the Irkutsk region of Siberia witnessed the fall of a large glowing object from space. Witnesses saw a large fireball in the sky, followed by a thunder-like sound, a flash of light, and a small earth tremor. Scientists from the Institute of Solar and Earth Physics of the Russian Academy of Science suspect the object is a large... View More (2002-10-04)
UCSB geologist discovers pattern in Earth's long-term climate record
In an analysis of the past 1.2 million years, UC Santa Barbara geologist Lorraine Lisiecki discovered a pattern that connects the regular changes of the Earth's orbital cycle to changes in the Earth's climate. View More (2010-04-07)
U of M researchers unlock mystery of layer encircling the Earth's core
University of Minnesota associate professor of chemical engineering Renata Wentzcovitch and her team of researchers have confirmed the properties of a mineral (post-perovskite) that may form near the Earth's core in a layer called the D'' region. View More (2006-01-31)
McGill researchers find oldest rocks on Earth
McGill University researchers have discovered the oldest rocks on Earth - a discovery which sheds more light on our planet's mysterious beginnings. View More (2008-09-26)
UBC study may solve age-old mystery of missing chemicals from Earth's mantle
Observations about the early formation of Earth may answer an age-old question about why the planet's mantle is missing some of the matter that should be present, according to UBC geophysicist John Hernlund. View More (2007-12-06)
Scientists probe Earth's core
We know more about distant galaxies than we do about the interior of our own planet. However, by observing distant earthquakes, researchers at the University of Calgary have revealed new clues about the top of the Earth's core in a paper published in the May edition of the journal Physics of the Earth and Planetary Interiors.

No Core In Volcanoes
A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how the Earth's magnetic field is sustained. The magnetic field results from the movement of liquid... View More (2004-01-12)
Moon and Earth Formed out of Identical Material
According to the «Giant Impact» theory the moon was formed by a collision between a proto-earth and a smaller planet. In the October 12 issue of Science, ETH researchers present results showing that the composition of the oxygen isotopes of the moon and the earth are identical. This is a strong indication that the proto-earth and the planet with which it collided were formed from an... View More (2001-10-11)
Missing chromium is clue to planet formation
Early in the formation of the Earth, some forms of the element chromium separated and disappeared deep into the planet's core, a new study by UC Davis geologists shows. View More (2011-02-25)
Unexpected discovery about earth's core
The core of the earth doesn't look the way it was expected to. Scientists at the Royal Institute of Technology in Stockholm, Sweden , KTH, can now show that iron, under extremely high pressure, such as that found in the inner earth, takes on unexpected properties, and this can be of importance in understanding the movements of the earth, such as, earthquakes. The results are being presented in... View More (2003-08-29)
Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature. View More (2006-05-11)
Rivers on Titan, one of Saturn's moons, resemble those on Earth
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice. View More (2005-12-06)
IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was attended by officials from more than 30 countries hoping to create an integrated Earth Observation... View More (2003-08-06)
Silicon May Have Been The Key To Start Of Life On Earth
A scientist at the University of Sheffield has discovered that silicon may have been key to the establishment of life on earth. Until now it has generally been thought that bacteria do not interact with silicon, but Dr Milton Wainwright and his team at the University's Department of Molecular Biology and Biotechnology, has found that this is not the case. In a paper, due to be published in the... View More (2003-10-23)
A "Swarm" of satellites for a unique look inside the Earth
ESA's Earth Observation Programme Board has just decided which of the six Earth Explorer candidate missions, presented earlier in April at the User Consultation Meeting, will be developed and launched. Swarm, an Earth Explorer Opportunity Mission, is a constellation of satellites which will study the Earth's magnetic field. A further selection between the Earth Explorer Core Missions EarthCARE...

Did comets flood Earth's oceans?
Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth's oceans? The Ptolemy experiment on Rosetta may just find out" The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs - frozen reservoirs of water orbiting the Sun. Did the impact of a... View More (2004-06-16)
Delft research increases understanding of Earth's magnetic field
Research recently conducted at Delft University of Technology marks an important step forward in understanding the origins of the Earth's magnetic field. The research findings are published this week in the scientific journal Physical Review Letters. View More (2007-03-12)
EARTH: Geotubes -- from sludge to shoreline protection to surfing
What do geology and textiles have in common? More than you might think. Since the 1980s, coastal, ocean and hydraulic engineers have been reinforcing coastlines and cleaning up contaminated water from dredge materials and other sludges and slurries with a revolutionary fabric that combines the strength of certain textiles with geoscientific know-how.

Geologists point to outer space as source of the Earth's mineral riches
According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin. View More (2009-10-19)
