Come ponder the universe’s vast wonderland. Begin by putting everything into perspective with a grand tour from Earth to the Big Bang, then examine the lives of stars and the key role they play in the creation of the elements that comprise our world. We will also discuss the simplest yet scariest objects of all, black holes. Then we’ll look at the variable sky, especially new “movies” of the sky being made and the crazy celestial menagerie they reveal. In the final session, learn about NASA’s amazing Chandra X-ray Observatory, right here in the Boston area. Learn about the recent discoveries Chandra has made during its two decades in orbit. Specifically designed to investigate very hot regions of the universe by resolving celestial X-ray sources with unprecedented precision, Chandra has greatly advanced the field of X-ray astronomy. See how its discoveries have illuminated exploded stars, clusters of galaxies, and the doomed matter around black holes.
