"The beautiful and mysterious auroras are spectacular to watch, but they are actually a manifestation of violent space weather. This weather can create big problems here on Earth by disrupting power grids, satellites, air travel and even GPS signals.... While auroras have fascinated observers for centuries, little had been known about their origin. But NASA is aiming to resolve this mystery with a new mission called THEMIS." (02:15)

In this interactive activity adapted from NASA, learn about how X-rays are one type of electromagnetic radiation that astronomers use to study the universe. Investigate how the wavelength, frequency, and energy of an electromagnetic wave are related.... Explore X-ray images of astronomical objects, and learn about how X-ray detectors work. In addition, learn why the Chandra telescope uses barrel mirrors to collect X-rays.

As featured on the Nov. 9 2011episode of the Colbert Report!
From the Low Temperature Lab: A flux-pinning enhanced superconducting puck levitates above and is pinned to a magnetic figure-8 track. This demonstrates the quantum physical effect of supe...rconductivity and the Meissner Effect as well as magnetic flux pinning. The puck is accelerated using the motors from a toy car track set. See more at our website:http://www.ithaca.edu/hs/depts/physics/facstaff/mcsullivan/ and our paper here: http://arxiv.org/abs/0803.3090
