Here is the story. A NASA scientist, Dr. Richard B. Hoover, astrobiologist, believes that he has discovered an alien life form, closer that we could imagine. This discovery may also explain how life on earth started. He is so sure for his discovery, that he challenges anyone to prove to him his findings are wrong. This strange claim is a result of ten years of research with extremely rare form of meteorites, that have fallen in areas across the globe, such as Antarctica, Siberia and Alaska. These meteorites (CI1 carbonaceous chondrites) are actually so rare, that only 9 of them are known to exist on earth. So, after looking with microscopes, he said that he found many different fossils of bacteria. Some of them are similar to the ones that are found here on earth... some others are... not similar at all (thus alien). Read the complete article here.
