Astrophysicists use the intrinsic brightness of certain kinds of stars to determine the age of the universe. Dave Schlom talks with Don Neil, a scientific analyst with Galaxy Evolution Explorer, about the rich data that project has yielded — especially regarding these benchmark stars.
Blue Dot, named after Carl Sagan's famous speech about our place in the universe, features interviews with guests from all over the regional, national and worldwide scientific communities. Host Dave Schlom leads discussions about the issues science is helping us address with experts who shed light on climate change, space exploration, astronomy, technology and much more. Dave asks us to remember: from deep space, we all live on a pale, blue dot. Blue Dot is engineered, co-produced and co-hosted by Matt Shilts. It airs Thursdays at 10:30 a.m. and Fridays at 6:30 p.m.
