... Abstract: We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. ... We have explored the dependence of A_l on a conspicuous set of quantities (Hubble type, inclination, dust optical thickness, dust distribution and extinction properties) for a large wavelength interval, ranging from 1250A to the K band, thus finally providing a comprehensive atlas of dust extinction in galaxies, which is electronically available. ...

. Southwest Research Institute scientists developed a new process in planetary formation modeling that explains the size and mass difference between Earth and Mars. Mars is much smaller and has only 10 percent of the mass of Earth. Conventional solar system formation models generate good analogs to Earth and Venus but predict that Mars should be of similar-size or even larger than Earth. Courtesy of NASA/JPL/MSSS
