Ancient Earth hammered by double space impact

We've all seen the films where an asteroid hurtles towards our planet, threatening civilisation.

What's less well known is that menacing space rocks sometimes come in twos.

Researchers have outlined some of the best evidence yet for a double space impact, where an asteroid and its moon apparently struck Earth in tandem.

Using tiny, plankton-like fossils, they established that neighbouring craters in Sweden are the same age - 458 million years old.

The researchers make it sound like the idea of a simultaneous asteroids impacting a planet or a moon is some kind of mind blowing concept. They were clearly looking for the evidence. It's not as if they stumbled on a site and said "Whoa!".

It is interesting and unusual though. How often do you hear about an asteroid with a moon, let alone both of the hitting the Earth?

It's not as unusual as you might think. It's estimated that 10% of asteroids have moons.
