Hollywood may have got it right after all.

Nasa and the National Nuclear Security Administration have announced they are now working together on the possibility of destroying hazardous asteroids using nuclear weapons.

And like the film Armageddon - where Bruce Willis flies a space shuttle to an oncoming asteroid to drill a warhead into its core - the nuclear payload could be delivered by rocket.

'Often, these agencies focus on their own pieces of the puzzle, so anything that brings them together is a good thing,' said Bruce Betts, director of science and technology at the Planetary Society told the New York Times.

Scientists believe there are around one million near-Earth asteroids that could pose a threat to our planet – but only a tiny fraction have so far been detected.

Dramatic proof that any of these can strike Earth came on 15 February last year, when an unknown object exploded high above Chelyabinsk, Russia, with 20 - 30 times the energy of the Hiroshima atomic bomb.

The resulting shock wave caused widespread damage and injuries, making it the largest known natural object to have entered the atmosphere since the 1908 Tunguska event, which destroyed a forest area of Siberia.

Using a nuclear weapons to blow up asteroids may work particularly well on medium-sized asteroids and comets between 164 and 492 feet in diameter.

Some experts, however, claim that the resulting rock fragments could make the situation worse, and that deflecting an asteroid may prove to be a better solution.

Blowing up an asteroid with nuclear weapons has been proposed in the past.

Last year, an Iowa team outlined a similar vision at a Nasa conference, and say they would need just a weeks' notice to launch if the system were developed.

Called the Hypervelocity Asteroid Intercept Vehicle, or HAIV, the craft would rendezvous with an asteroid in deep space.

It consists of a leader spacecraft, which would hit the comet and create blast crater.

THERE IS AN ASTEROID WITH OUR NAME ON IT, SAYS BRIAN COX 'There is an asteroid with our name on it and it will hit us,' Professor Brian Cox told MailOnline While the latest claims of a killer asteroid are unfounded, scientists have long said that these space rocks pose a major threat to Earth. In September, Brian Cox said we are at risk of being wiped out by asteroids – and we're not taking the threat seriously. 'There is an asteroid with our name on it and it will hit us,' Professor Cox told MailOnline. In fact, the Earth had a 'near-miss' only a few months ago. 'We didn't see it,' says the 46-year-old. 'We saw it on the way out, but if it had just been a bit further over it would have probably wiped us out. These things happen.' The bus-sized asteroid, named 2014 EC, came within 38,300 (61,637km) miles of Earth in March - around a sixth of the distance between the moon and our planet. And it wasn't the only one threatening Earth. Nasa is currently tracking 1,400 'potentially hazardous asteroids' and predicting their future approaches and impact probabilities. The threat is so serious that former astronaut Ed Lu has described it as 'cosmic roulette' and said that only 'blind luck' has so far saved humanity from a serious impact. Advertisement

Around a millisecond later, a follower spacecraft carrying nuclear explosives would hit inside the crater - which increases its effectiveness by up to 20 times.

Over the past two decades, Nasa has been looking for dangerous near-Earth asteroids larger than 1km in size, and claims to have found 98 per cent of them.

But existing asteroid detection systems can only track one per cent of the estimated objects that orbit the sun, according to asteroid mining firm Planetary Resources, who is partnering with Nasa on the project.

In a session at the SXSW conference in Texas last year, Nasa scientist Jason Kessler said: 'The likelihood of something hitting us in the future is pretty guaranteed, although we're not freaking out that there is an imminent threat.'
