Follow Dr. Alex Fillippenko and his High-Z Supernova Search Team to Mauna Kea volcano in Hawaii, where they will study space phenomena and look for supernovae, dying stars that explode with the power of billions of hydrogen bombs. Dr. Fillippenko looks for black holes--areas in space with such a strong gravitational pull that no matter or energy can escape from them--with his robotic telescope. And they study the effects of dark energy, the mysterious...

In July of 2015 a robotic spacecraft reached Pluto after a nine-and-half-year journey. New Horizons is the first spacecraft mission to Pluto and revealed its five moons as never before seen. Images from the mission show a reddish surface covered in ice-water mountains, moving glaciers, and hints of possible ice volcanoes and an underground ocean. Pluto is geologically alive and changing! This addition to the Scientists in the Field series goes...
