“The fields of Cosmology and Astrophysics are at a Golden Age;  groundbreaking discoveries are made frequently — from dark matter to the accelerated expansion of the Universe, to supermassive black holes, to planets around other stars. Our Cosmic horizon of discovery is opening wider and deeper.  Yet, the nature of dark matter, and the newly discovered dark energy that causes the cosmic acceleration, remain a puzzle."
