Two events that may be of interest to DC Geology Events subscribers, both from the Carnegie’s “Capital Science Lectures” series:
A presentation by author and Washington Post science writer Marc Kaufman, followed by a discussion with Carnegie planet-hunter Paul Butler.
Recent discoveries have convinced many astronomers that our galaxy is home to billions of exoplanets and that other galaxies have hundreds of billions more. The search is now on for distant planets in “habitable zones,” where water is sometimes liquid and the possibilities for life are greatest. With a scientific consensus forming that these potentially life-sustaining planets also number in the billions, the logic for the existence of extraterrestrial life grows stronger all the time.

In 1998 two teams traced back the expansion of the Cosmos over billions of years and discovered that the Universe was accelerating, a startling discovery that indicated more than 70% of the Cosmos was some previously undetected form of matter, known as Dark Energy. Brian Schmidt, leader of the High-Redshift Supernova Search Team, will describe this discovery and explain how astronomers have used observations to trace our Universe’s history back more than 13 billion years, leading them to ponder the ultimate fate of the Cosmos.
