Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread ...

Some 3,000 light years away, shimmering layers of gas formed an almost perfect sphere around the faintly glowing, burned-out core of a dead star. The result looks like a giant crystal ball floating in ...

Chondritic meteorites (chondrites) are some of the oldest rocks in our solar system, forming 4.5 billion years ago. Therefore, their primitive composition means that they offer a window into the ...

could have produced conditions that allowed rapid mineral hydration. Fred J. Ciesla, Dante S. Lauretta and Lon L. Hood of the UA and Barbara Cohen of the UH collaborated in the study. Lauretta and ...
