NASA scientists had been searching everywhere over a year for any proof of life in the neighborhood and distant planets that might indicate alien life. Scientists though believe they will be found in 20 years if they really do exist. Life forms that were recently found had shown no sophisticated development that supports alien existence. The new study that involved 100,000 galaxies came out negative of any alien life. There are at least one hundred billion galaxies in the universe according to research. The number investigated can be considered as a drop in the bucket.
Data of a space-based infrared telescope from NASA’s WISE observatory were examined by researchers at Penn State University. They tried finding any proof that might indicate alien life which resulted with no certain evidences.
