A NASA scientist believes he has discovered an alien life form which may explain how life on earth started and has called on any scientist worldwide to try and prove him wrong.

The extraordinary claim by Dr Richard Hoover, an astrobiologist with NASA’s Marshall Space Flight Center, comes after ten years of studying tiny bacteria in meteorites that have fallen in remote areas across the globe.

He explains that travelling to Antarctica, Siberia and Alaska he has studied an extremely rare form of meteorites – CI1 carbonaceous chondrites – of which only nine are known to exist on earth.

Research claims fossilised bacteria from meteors, like this one which is similar to Titanospirillum velox which is found on earth, suggests life is more widespreadIs this what an alien looks like? Research claims fossilised bacteria from meteors appear similar to bacteriafound on earth – like Titanospirillum velox, above. That suggests life is more widespread than we think.

Looking at these meteorites under microscopes he said he has found numerous different fossils of bacteria – some which are similar to ones on earth and others which are complete, um, alien.

He suggests that meteors spread organisms around the universe and that life on earth could have been planted by bacteria in an asteroid hitting the planet in its infancy.

In one case he found on a meteorite an organism similar in size and overall structure to the giant bacterium Titanospirillum velox, an organism found here on planet Earth.

He suggests this proves life is more widespread than we first thought.

Discovery: Dr. Richard B. Hoover has challenged anyone to prove to him his findings are wrongDiscovery: Dr. Richard B. Hoover has challenged anyone to prove to him his findings are wrong.

He told Fox News:

“I interpret it as indicating that life is more broadly distributed than restricted strictly to the planet earth. This field of study has just barely been touched — because quite frankly, a great many scientists would say that this is impossible.

The exciting thing is that they [the bacteria] are in many cases recognisable and can be associated very closely with the generic species here on earth.

There are some that are just very strange and don’t look like anything that I’ve been able to identify, and I’ve shown them to many other experts that have also come up stumped.”

Dr Hoover would collect each meteorite stones and break them in laboratory conditions, scanning for fossilised remains.

It was then he made his discovery, identifying one biological remain as having no nitrogen – something that, until now, is found in all living organisms.
