Astrobiologist Dr. Richard Hoover works with NASA’s Marshall Space Flight Center and has been studying the tiny bacteria that is found within meteorites. Having travelled the globe while studying these bacteria for ten years, he now believes that he has discovered a foreign life form that could explain the beginning of the life on Earth.
A close up of a meteorite that came from far, far away...
While in places such as Antarctica, Alaska, and Siberia, he has had the chance to observe rare forms of meteorites known as CI1 carbonaceous chondrites. There are only nine of these known to exist around the world. These meteorites contain a variety of bacteria fossils. Some of these are similar to bacteria found here, such as one that looks like a variety known as Titanospirillum; others are completely alien and look like nothing found here before.
Hoover’s theory suggests that organisms were spread throughout the universe by the meteors. It also states that life on our planet could possibly have been due bacteria living in a meteorite and falling to Earth. he data he has collected could possibly be interpreted to show that life is not solely restricted to one planet, but that it is possible for it to have existed elsewhere in the universe. Many scientists would disagree, however, believing that the entire idea is impossible.
The discovery was made while he was researching the insides of meteorites he had collected and found that one contained biological remains that had no nitrogen, an element that is found in every living thing. This find has stumped many, and Hoover has challenged others to explain how such a remain without even a traceable amount of nitrogen is possible.
If Hoover’s theory is proven to be true, it would suggest that life began outside of Earth and came here during the planet’s infancy. Many are hesitant to believe in the possibility, and many of the tests are likely to be highly scrutinized by the scientific community.
