The Final Frontier: A Horizon Guide to the Universe 2012 BBC 60min

Seven segments of less than ten minutes look at the subject using clips from the Horizon series of science documentaries which started in 1964:

1 - The laws of gravity as revealed by Newton and Einstein.
2 - Hubble's discovery that the universe is expanding from the red shift of light from distant galaxies.
3 - The Hubble space Telescope, its repair and its discoveries.
4 - The search for life on mars, the meteorite "microfossils" and the Curiosity rover
5 - The discovery of Exoplanets detected using star wobbles with ultrasensitive spectroscopes.
6 - The Higgs Boson and its discovery using the Large Hadron Collider.
7 - Before the big bang - speculation and theories about the ultimate question.

The segments are too short to develop any real interest in the themes although if you are coming fresh to any of it you may have your curiosity piqued to find out more - there are decent books available that explore these subjects in more depth.
