In this video from NOVA’s Sun Lab, learn about the Sun’s composition and structure. The Sun is a plasma, primarily made of hydrogen with smaller amounts of other elements. Animations and images illustrate the physical and behavioral properties of the Sun’s six regions: the core, radiative zone, conv
Exploring melting under microgravity conditions – improving industrial casting processes One of the focal points of research onboard the International Space Station (ISS) is the investigation of crystal growth in metal alloys. Under microgravity conditions, differences in density in the molten mate
In this video we will learn how Alfred Wegener proposed a theory in 1912 that the great continents of the Earth had drifted over geological time and were once all joined together in a giant land mass we now call Pangaea. His idea was based on the way present day continents fit neatly together, and
