Secrets of Our Universe with Tim Peake sees British astronaut Tim Peake take us on an out of this world journey — literally — as he searches for answers to some of the Universe's BIG questions.

Having spent six months orbiting Earth, Tim has a rather different perspective on space from the rest of us. And the 51-year-old puts his knowledge to good use in Channel 5 series, in which he looks at space missions, stars, black holes and the solar system.  

Tim Peake said of presenting the new show: “Space is a lifelong passion for me and to be able to share my personal experiences and the knowledge I have gained with the Channel 5 audience is beyond exciting!

"There is always so much more to learn and uncover — we will never truly know all there is to know about the Universe — but it is endlessly fascinating to me and to people worldwide, and I am delighted to continue my journey into uncovering its mysteries.”
