Looking backwards, using fossil evidence from nearby galaxies provides a plausible picture of how galaxies have formed over cosmic time. Also, going forwards, the present quite definite cosmological model, shows how perturbations grew from low amplitude fluctuations via standard physical processes to the present world. Finally, we can employ large telescopes as a time-machines – directly observing the past history of our light-cone. While none of these approaches gives results accurate to more than 5-10%, a plausible picture emerges. Massive galaxies form in two phases.
A field of physics that is growing in interest worldwide that tackles such astrophysical phenomena as the source of violent space weather and the formation of stars.
Princeton University and the Max Planck Society of Germany have joined forces in a scientific collaboration that is designed to accelerate progress in cutting-edge research ranging from harnessing fusion to understanding solar storms.
