Event

Join Evan Lewis, a graduate student at West Virginia University for a lecture on pulsars. Pulsars are incredibly dense neutron stars formed from the collapsed cores of massive stars after supernova explosions. A single teaspoon of their material would weigh as much as Mount Everest, and they often rotate several times per second—some even hundreds of times! They also have magnetic fields far stronger than anything humans can create. Pulsars emit beams of radio waves from their poles, and as they spin, these beams sweep across space like a cosmic lighthouse. Because their pulses are so regular, pulsars can be used as precise cosmic clocks, rivaling the best human-made timekeepers.

Evan Lewis is a sixth-year graduate student at West Virginia University, where he uses radio telescopes to take observations of pulsars. He spent over a year working in the WVU Planetarium, where he gave weekly public presentations as well as tours for school field trips and other groups.

Event Report

Comments and anecdotes about the event:
This was one of our best presentations since the club's inception. The speaker, Evan Lewis, had spent over a year working in the West Virginia University Planetarium, where he gave weekly public presentations, as well as tours for school field trips and other groups. This really showed as he answered complicated questions from experienced amateur astronomers, less experienced adults, and children with equal enthusiasm and replies that matched the questioners knowledge level. The sprinkling of humor throughout his presentation created a relaxed atmosphere. One of the interesting historical facts was that pulsars were first discovered by a woman, Jocelyn Bell Burnell, while she was a post-graduate student at New Hall, England. Her academic advisor, however, won the Nobel Prize for the discovery, even though he first discouraged her investigation of what he assured her was an Earthly artifact. It was only in later years that she gained the reputation that she deserved.
