Shocking Exposures

Part 1 Looks at man's exploration of outer space. In 1923, astronomer Edwin Hubble took a photo that provided the first clue in calculating the size of the universe by showing that the Andromeda galaxy is not part of our Milky Way but lies far more distant. The film covers this and many other amazing images, including the Apollo photos from the Moon's surface and Copernicus' diagram of the solar system with the Sun, rather than the Earth, in the centre.

Part 2 Looks at the world of micro-imagery. Neuroscientist Joseph Altman's images from the early 1960s proved that new brain cells are created, even in adult brains. Other groundbreaking images in this episode include Andreas Vesalius' detailed drawings of the inside of the human body and Raymond Gosling and Rosalind Franklin's X-ray diffraction image that became a vital piece of the puzzle in the search for the structure of the DNA molecule.
