Sounds like from the wonderful composer & cellist Phillip Sheppard https://soundcloud.com/radiomovies/across-the-milky-way for the documentary "Inside the Milky Way" https://www.youtube.com/watch?v=xwSQVSlccCg
Here is another place that clarify it was him behind the contemporay music https://philipsheppard.bandcamp.com/track/across-the-milky-way "(This piece is a development of the title track of my score for 'Inside the Milky Way')"
