New 'Blue Marble' picture delights

A new, full snapshot of our planet has been captured by a US satellite.

Such images, which show the Earth in its entirety, are known as "Blue Marbles".

The latest of these was captured by the US DSCOVR Earth observation satellite, which was launched in February this year.

The original Blue Marble, taken by the crew of Apollo 17, is thought by some to be the most reproduced photo of all time.
