Two Solar System Puzzles Solved
July 25, 2012
How did icy comets obtain particles that formed at high temperatures, and how did the particles acquire rims with different compositions? Carnegie Institution scientists are the first to model the trajectories of refractory particles in the unstable disk that formed the solar system. The scientists found particles could have been processed in the hot inner disk, and then traveled to the frigid outer regions to end up in icy comets.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
