Is There Life Out There?

 For as long as we can remember, humans have wondered if we are alone in the universe.In fact, in September 2013, a team of British scientists claimed a cell fragment found by a balloon flight in the upper atmosphere may be proof of life from space. While individuals and conspiracy theorists often come forward with new "proof" of alien visitations, even scientists have claimed to find evidence for extraterrestrial life.

While individuals and conspiracy theorists often come forward with new "proof" of alien visitations, even scientists have claimed to find evidence for extraterrestrial life. Here are our top five scientific claims for aliens. FIRST STOP: Microbes in Meteorites Microbes in Meteorites Credit: Hoover/Journal of Cosmology NASA scientist Richard Hoover published a paper March 4, 2011, claiming to have found fossil evidence for cyanobacteria in carbonaceous meteorites from outer space. Hoover observed slices of meteorites through scanning electron microscopes, and identified filaments and structures that he said resemble the tiny single-celled algae. Reaction from some scientists was skeptical, in part because the study was published in the questionable Journal of Cosmology. Other researchers said the study was conducted thoroughly, but it was too soon to say for sure whether the claim would hold up.
