This resource gives an impression of how immense our Universe is by employing a method used many times in "Power of 10" films - that is, starting with an image of the Earth and then zooming out towards the furthest visible reaches of our Universe. This is not, however, an exercise in "powers of 10" - on the contrary, the goal is to show astronomical distances without scientific notation. It focuses ... Full description.

This product illustrates how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. The Dawn spacecraft contains three instruments -- the Gamma Ray and Neutro Detector (GRaND), the Visible Infrared Spectrometer, and the Framing Camera -- that will provide answers to questions about the formation and evolution of the early solar system.
