Meteorite search update
Investigation of the fireball that lit up the skies of Alberta and Saskatchewan on November 20 has determined that an asteroid fragment weighing approximately 10 tonnes entered the Earth's atmosphere over the prairie provinces last Thursday evening.   view more (2008-11-26)

MIT researchers find clues to planets' birth
Meteorites that are among the oldest rocks ever found have provided new clues about the conditions that existed at the beginning of the solar system, solving a longstanding mystery and overturning some accepted ideas about the way planets form.   view more (2008-10-31)

University of Western Ontario cameras capture 'fireball'
For the second time this year, The University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. The team of astronomers suspects the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few... view more (2008-10-27)

The first new mineral with post-spinel structure is approved by CNMNC of IMA
Xiete is the first new mineral with post-spinel structure found by a Chinese-American team from the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences and the Geophysical Laboratory, Carnegie Institution of Washington, which has recently been approved by the Commission on New... view more (2008-09-12)

Cosmic connections: Imperial scientist locates the origin of cosmic dust
The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space.   view more (2008-09-03)

Discovery of the source of the most common meteorites
When observing with the GEMINI telescopes, two astronomers from Brazil and the United States discovered for the first time asteroids that are similar to "ordinary chondrites", the most common meteorites found on Earth. Until now, astronomers have failed to identify their asteroidal... view more (2008-07-11)

Laser fluorescence could find life on Mars
A team of scientists from the United States and the United Kingdom has developed a technique using ultraviolet light to identify organic matter in soils that they say could be used to document the existence of life on Mars.   view more (2008-06-23)

Lavas from Hawaiian volcano contain fingerprint of planetary formation
Hikers visiting the Kilauea Iki crater in Hawaii today walk along a mostly flat surface of sparsely vegetated basalt. It looks like parking lot asphalt, but in November and December 1959, it emitted the orange glow of newly erupted lava.   view more (2008-06-20)

Scientists confirm that parts of earliest genetic material may have come from the stars
Scientists have confirmed for the first time that an important component of early genetic material which has been found in meteorite fragments is extraterrestrial in origin, in a paper published on 15 June 2008.   view more (2008-06-16)

Ancient mineral shows early Earth climate tough on continents
A new analysis of ancient minerals called zircons suggests that a harsh climate may have scoured and possibly even destroyed the surface of the Earth's earliest continents.   view more (2008-06-16)

Simple membranes could have allowed nutrients to pass into primitive cells
When the first cells developed, how could they bring molecules from the environment into their living interior without the specialized structures found on the modern cell membrane?   view more (2008-06-05)

FSU geochemist challenges key theory regarding Earth's formation
Working with colleagues from NASA, a Florida State University researcher has published a paper that calls into question three decades of conventional wisdom regarding some of the physical processes that helped shape the Earth as we know it today.   view more (2008-05-01)

Refining the date of the K/T boundary and the dinosaur extinction
Scientists at the University of California, Berkeley, and the Berkeley Geochronology Center have pinpointed the date of the dinosaurs' extinction more precisely than ever thanks to refinements to a common technique for dating rocks and fossils.   view more (2008-04-25)

Geologists Discover New Way of Estimating Size and Frequency of Meteorite Impacts
Scientists have developed a new way of determining the size and frequency of meteorites that have collided with Earth.   view more (2008-04-14)

Meteorites delivered the 'seeds' of Earth's left-hand life
Flash back three or four billion years - Earth is a hot, dry and lifeless place. All is still. Without warning, a meteor slams into the desert plains at over ten thousand miles per hour. With it, this violent collision may have planted the chemical seeds of life on Earth.   view more (2008-04-07)

UMd-led team finds ancient asteroids formed at solar system's start
Using visible and infrared data collected from telescopes on Hawaii's Mauna Kea, a team of scientists, led by the University of Maryland's Jessica Sunshine, have identified three asteroids that appear to be among our Solar System's oldest objects.   view more (2008-03-24)

Mars Express reveals the Red Planet's volcanic past
A new analysis of impact cratering data from Mars reveals that the planet has undergone a series of global volcanic upheavals. These violent episodes spewed lava and water onto the surface, sculpting the landscape that ESA's Mars Express looks down on today.   view more (2008-03-17)

Meteorites are rich in the building blocks of life, claims new research
Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today.   view more (2008-03-14)

Meteorites a rich source for primordial soup
The organic soup that spawned life on Earth may have gotten generous helpings from outer space, according to a new study. Scientists at the Carnegie Institution have discovered concentrations of amino acids in two meteorites that are more than ten times higher than levels previously measured in... view more (2008-03-14)

Brown Scientist Answers How Peruvian Meteorite Made It to Earth
Brown University professor Peter Schultz's study of the Peruvian meteorite has yielded some interesting conclusions that could upend the conventional wisdom about the size and type of meteorites that can strike Earth.   view more (2008-03-12)

Canadian astronomers on hunt for meteor
Astronomers from The University of Western Ontario in London, Ontario, have captured rare video of a meteor falling to Earth.   view more (2008-03-10)

ASU researcher may have discovered key to life before its origin on Earth
An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to... view more (2008-02-29)

Earliest Stage of Planet Formation Dated
UC Davis researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago, within a range of about 2,080,000 years.   view more (2007-12-20)

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)

Extraterrestrial Impact Likely Source of Sudden Ice Age Extinctions
At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures - giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan.   view more (2007-09-25)
