An important aspect of our model is that, although chondrules accumulate to form chondrites on small bodies, the chondrules themselves are formed by impacts on much larger bodies. Because of this, ...

You and I got here by way of the stars. They fused simple elements like hydrogen and helium in their cores into more complicated ones like carbon, oxygen, nitrogen, phosphorus and iron crucial for ...

A normally staid scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. At issue is how numerous small, glassy spherules had become ...

Jupiter is the largest planet in our solar system (so large, in fact, that some scientists think it might have even consumed other worlds), a gas giant so massive that it shaped the orbits and ...

Researchers propose a new model to explain the formation of most of the meteorites that make it to Earth. By Jonathan O’Callaghan “Droplets of fiery rain.” That’s how Henry Clifton Sorby, a ...

BLOOMINGTON, Ind. -- The process that formed the giant planet Jupiter may also have spawned some of the tiniest and oldest members of our solar system -- millimeter-sized spheres called chondrules, ...

The process that formed the giant planet Jupiter may also have spawned some of the tiniest and oldest members of our solar system -- millimeter-sized spheres called chondrules, the major part of the ...

April 26, 1803 was an unusual day in the small town of L'Aigle in Normandy, France – it rained rocks. Over 3,000 of them fell out of the sky. Fortunately no one was injured. The French Academy of ...

It has been proposed that some meteorites, CB and CH chondrites, contain material formed as a result of a protoplanetary collision during accretion. Their melt droplets (chondrules) and FeNi metal are ...

Until now, it has been generally accepted that a meteor constitutes a time capsule – a relic of the early creation of the solar system that has fallen to Earth, allowing us to delve into the distant ...

WEST LAFAYETTE, Ind. -- Asteroids may be a byproduct of planet formation rather than planetary building blocks, according to a recent paper in Nature. Research done at Purdue University suggests ...
