Scientist refines cosmic clock to determine age of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. view more (2005-06-30)
Carnegie scientists fine-tuning methods for Stardust analysis
On Sunday, January 15, NASA's Stardust mission landed safely with the first solid comet fragments ever brought back to Earth. Members of the mission's Preliminary Examination Team, including several from the Carnegie Institution's Geophysical Laboratory and Department of Terrestrial Magnetism, are among the first to analyze these precious samples. view more (2006-03-23)
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)
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)
No Need To Fly To The Moon For Lunar Soil
It is not necessary to fly to the Moon to get lunar soil even if the sample is required from the other side of this planet. A meteorite originating from the other side of the Moon has recently got into the hands of scientists. The meteorite investigation required precision instruments and grants from the Russian Foundation for Basic Research and... view more... (2005-05-13)
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)
Mars meteorite similar to bacteria-etched earth rocks
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria. view more (2006-03-24)
Is life the rule or the exception? The answer may be in the interstellar clouds
Is life a highly improbable event, or is it rather the inevitable consequence of a rich chemical soup available everywhere in the cosmos? Scientists have recently found new evidence that amino acids, the `building-blocks` of life, can form not only in comets and asteroids, but also in the interstellar space. This result is consistent with... view more... (2002-05-28)
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... view more... (2002-10-04)
Study highlights role of hit-and-run collisions in planet formation
Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and meteorites. view more (2006-01-12)
'Ultra-primitive' particles found in comet dust
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. view more (2009-11-03)
Solar wind tans young asteroids
A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought -- in less than a million years, the blink of an eye for an asteroid. This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will... view more... (2009-04-23)

Primitive asteroids in the main asteroid belt may have formed far from the sun
Many of the objects found today in the asteroid belt located between the orbits of Mars and Jupiter may have formed in the outermost reaches of the solar system. view more (2009-07-16)
Soyuz rocket fails on launch from Plesetsk cosmodrome carrying ESA experiment payload
ESA PR 65-2002. A Russian Soyuz launcher exploded some 20 seconds after lift-off from the Russian Plesetsk cosmodrome last night, 15 October, at 20:20 CEST. The launcher was carrying the unmanned Foton M-1 research satellite, using capsules of the Foton/Bion family containing 44 experiments supported by ESA. The experiments (*) covered a wide... view more... (2002-10-16)
ASU geologists suggest Mars features are result of meteorite strikes, not of evaporated lakes
Geologic features at the Opportunity landing site on Mars were formed not by a lake that evaporated but by constant strikes from meteorites, say two Arizona State University geologists. view more (2005-12-22)
ISO finding questions accepted theory that liquid water was present in young solar system
Planet-like bodies with liquid water formed very early in the history of the Solar System, or so scientists used to think. That scenario may now be due for revision after a finding with ESA`s Infrared Space Observatory, ISO. The theory was based on the presence of certain minerals called carbonates in primitive Solar System objects. Carbonates are... view more... (2002-01-17)
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)
Stardust parachutes to soft landing in Utah with dust samples from comet
Nearly seven years after setting off in pursuit of comet Wild 2, the Stardust return capsule streaked across the night sky of the Western United States early Sunday, making a soft parachute landing in the Utah desert southwest of Salt Lake City. view more (2006-01-16)
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... view more... (2004-06-16)
