Spectroscopy - Splitting the Starlight

How do we know what stars are made of? Starlight contains millions of fingerprints - spectral lines, which are produced by chemical compounds in the form of molecules, atoms, which are present in the atmospheres of stars and planets. The films shows how scientists decode stellar light and

Building a star from bits and bytes

How large is the Sun, how hot and how old is it? Much of what we know about stars comes from the models built upon fundamental laws of physics. Building stars in the terrestrial laboratories is impossible, buiding stars in a computer is. But computer models allow us to “see” below the surf
