This finding has provided a novel method to detect life on an exoplanet. For a long time, the presence of oxygen in the atmosphere of a planet has been believed to be evidence of possible life existence. With the James Webb Space Telescope set to be launched in 2019, David Catling, co-...

An exoplanet census Of the more than 5,000 exoplanets that have been detected since, more than 4,000 of them were discovered through the transit method. Most of those observations were made by the exoplanet-huntingKepler space telescope, which for four consecutive years kept an eye on a sma...
Two prominent scientists update our view of the history of life on Earth, featuring the prominent roles of oxygen and carbon dioxide, and question claims that it is fairly easy to initiate life—even on a planet such as ours
