In Chandra's Cosmos, Wallace Tucker, Science Spokesperson for the Smithsonian Astrophysical Observatory’s Chandra X-ray Center, uses an informal narrative along with dramatic color images to describe discoveries made by the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built.

On July 23, 1999, Chandra, the X-ray equivalent of NASA’s Hubble Space Telescope, was launched aboard the Space Shuttle Columbia into an elongated orbit that takes it as far as 86,000 miles from Earth. Chandra has given the world a view of the hot, high-energy regions of the universe that is largely hidden from telescopes sensitive only to visible light.

Wallace Tucker Chandra's CosmosThe book is organized in three parts: "The Big," covering the cosmic web, dark energy, dark matter, and clusters of galaxies, the largest bound objects in the universe; "The Bad," exploring neutron stars, stellar black holes, and supermassive black holes; and "The Beautiful," discussing stars, supernovas, exoplanets, and life.

Tucker is the author of seven previous books, five of which are for a general audience, including Revealing the Universe, co-authored with Karen Tucker, and The X-ray Universe, with Riccardo Giacconi, the 2002 recipient of the Nobel Prize in Physics. Tucker has been author or co-author of numerous scientific and popular articles on astrophysics, and has written three prize-winning stage plays, one of which was published in the anthology, Stories Of Our Way: An Anthology of American Indian Plays. He is also active in land conservation, having co-founded the Fallbrook Land Conservancy, which has preserved more than 2,000 acres of conservation land, and served as the conservancy's chairman for 24 years.

Tucker’s presentation will include a showing of some of the latest images made by Chandra, followed by Q&A with the audience. The evening concludes with book sales and signing.
