  The Northern Lights are amazing, in so many ways. How they come about is not fully understood, but it goes something like this: The Earth has a core made of molten iron. This creates a magnetic field and is why we have North and South Poles. The...

There is a story that originated back in the 1950s and 1960s, during the Space Race between Russia and the USA. I think it may have featured in an episode of The West Wing. I’m not big on political dramas, in fact I’m not really into...

This photograph is amazing. It was taken from 6 billion km away, beyond the orbit of Pluto. Earth has never been photographed from further away before or since. The photo is known as “Pale Blue Dot” and was taken by the Voyager space probe in 1990....
