Where can I find the awesome music from this video?

I heard today that Einstein’s prediction about gravitational waves is turning out to be true.

So I looked up this video about the topic and the music started out really good and then suddenly it became orgasmic – at least, IMO.

I MUST know the name of the track they used and how to find it. I assume it’s something in the public domain? Like in one of those sites where people compose free music just like there are stock photos? It’s just SO EPIC I must find an mp3 of it or at least a way to rip this video into an mp3.
