How the Universe Works, Supernovas

The greatest story ever told is the creation of everything, including us, out of nothing. The universe came into existence 13.7 billion years ago, growing from a minuscule point to the vast cosmos we see today.

We're taking a look at how stars are created and the dynamic role they play in both shaping and changing our universe.

Black holes are the most powerful and mysterious phenomena in the universe. For years, their existence was only speculation, but modern astronomy is proving them frighteningly real and showing that they shape everything we see.

Galaxies are home to stars, planets and us, and come in all shapes and sizes. From clouds of cold gas floating in the voids of space 13 billion years ago, galaxies evolved into the magnificent spirals that fill our night sky.

We get a better understanding of our planet's turbulent origins by studying how moons are born, how they live and die.

The study of supernovas helps humankind get a better understanding of our history as well as where we're going in the future.
