Supermoon Lunar Eclipse
The montage shows the progression of the September 2015 lunar eclipse over a period of about two hours, as Earth's curved shadow passes across it. Unusually, this eclipse coincided with a so-called supermoon, where the full moon is at the closest point in its orbit and appears slightly larger to the eye - such an event will not occur again until 2033. At totality the Moon is still visible as some sunlight still reaches it by passing through the Earth's atmosphere. However, it appears much dimmer and redder than normal - at a second the final exposure in the sequence is 1,000 times longer than the first. The deep red colour is caused by the same phenomena that makes our sky blue - our atmosphere scatters blue light more readily so that more red light reaches the Moon's surface, and is reflected back to Earth.
