Researchers from the University of Washington believe that a new study may help with the search for alien life on far away planets. In the past, research found that some planets create oxygen without the presence of biological organism, causing experts to believe that other worlds can sustain life. But it is believed that new findings will help determine the difference between life and the illusion of life, by identifying ‘biosignatures’ in the atmosphere of exoplanets. Researchers say this can be determined by studying the spectra features of light that is seen in the planet’s atmosphere as it transits. Funded by the NASA Astrobiology Institute, the research was published in Astrophysical Journal Letters. RT reports: But just because a planet has oxygen does not mean life is sustainable or present there. For example, Venus contains both oxygen and carbon dioxide, but its atmosphere is too hot and acidic to sustain life – so the oxygen is a ‘false positive.’ Ruling out such false positives is essential for scientists searching for life, and the researchers claim they have a found a way to do so easily. That process hinges on the process of spectroscopy, the study of spectral features of light [...]
