Blue Dot: Cosmic mysteries: dark matter and dark energy

ESA Euclid Mission to explore dark matter and dark energy.

ESA Euclid Mission to explore dark matter and dark energy.

Host Dave Schlom investigates two of the components that make up most of the universe -- dark matter and dark energy. While their effects are measurable, their nature remains essentially a mystery.

Dave is joined by one of the world's foremost astronomers, Dr. Wendy Freedman, from the University of Chicago, for a primer on dark matter and dark energy. Then Jet Propulsion Laboratory scientist Eric Huff, a member of the European Space Agency's Euclid Mission US/NASA team, joins us to talk about the upcoming mission.

Set to launch this summer, Euclid will attempt to unravel the mysteries of these two elusive threads in the fabric of space and time. It's a probe into the real dark side of the cosmos!

Dave Schlom is the longtime host and creator of Blue Dot. From surfing to Voyager in interstellar space, rock guitar to orcas in our imperiled oceans, the topics on Blue Dot are as varied as the host’s interests and connections -- which are pretty limitless! An internationally respected space history journalist, Dave is also deeply fascinated by all aspects of the grand workings of nature’s awesome machinery on scales ranging from galactic to subatomic. And topics take in all aspects of the arts and sciences.
