All you need to know about astrophysics without the equations.

Andrew Williams presents:
There's an awful lot of science fiction featuring stars, but usually as
a static backdrop to the story. That's because usually, stars transform
over time scales much longer than human lifetimes. They do change
though, from their birth in dense, cold gas clouds through to their
death as supernovae, or more likely, a slow fade into oblivion. This
presentation will explain how and why stars form, change, and die. There
will be lots of pretty pictures and videos, but no equations.

If you ever wondered how close Jupiter _really_ is to being a star
instead of a planet, exactly why heavy stars burn faster and die quicker
than light ones, or how Cepheid Variable stars expand and contract like
a beating heart, come along and find out.
