New way of detecting oxygen on exoplanets could help find life n The search for oxygen on other planets outside of our solar system,called 肖 exoplanets,is thought to be an aid in the search for life outside of Earth.Now, astronomers (1)(develop)a new method for detecting oxygen on exoplanets, 烟 according to a new study published Monday. The scientists believe their new method could speed up the search for life by making (2)easier to tell if individual exoplanets could host life on their surfaces by looking at their atmospheres. For example,if an alien species was searching for life outside of their planet,one n of the ways they (3)tell Earth hosted life is because of the presence of biosignatures,such as oxygen.Individual organisms like plants on Earth produce oxygen(4)_photosynthesis. The new method will rely on detecting the strong signal(5)(create)when oxygen molecules collide in the atmospheres of exoplanets.The method will be used by NASA's James Webb Space Telescope,(6)will be able to peer into the atmospheres of exoplanets and search for this signal.The telescope will launch later and take a closer look at mysterious exoplanet targets already identified by previous planet-hunting missions such as NASA's Kepler and TESS. This unique signal produced by oxygen molecule collisions could actually help astronomers decide (7)the planet hosts life or not.Once this determination (8)(make),they can quickly move on in the search. "Before our work,oxygen at similar levels as on Earth was thought(9)(be) undetectable with Webb,"said Thomas Fauchez,lead study author at NASA's Goddard Space Flight Center."This oxygen signal is known since the early 1980s from Earth's atmospheric studies but has never been studied for exoplanet research." The collision of the oxygen molecules is key (10)they block infrared
