A red dwarf star with seven Earth sized planets? Sound like science fiction? No, it is the Trappist-1 system recently discovered – and it rocked the science world because these are rocky worlds – maybe like Earth! Find out what we know and how we know it on this week’s show.

Blue Dot 47: Trappist-1 System

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.
