Question

Quizplus · Accepted Answer

Oxygen has not yet been detected in the atmospheres of exoplanets. While scientists have detected other molecules such as methane, carbon dioxide, and water in the atmospheres of some exoplanets, oxygen is a challenging molecule to detect because it is highly reactive and can easily bond with other elements to form different compounds. Therefore, the absence of oxygen in the atmosphere of an exoplanet does not necessarily mean that the planet cannot support life. Methane, carbon dioxide, and water have all been detected in the atmospheres of exoplanets, but there has not been a confirmed detection of oxygen. This is likely because oxygen is highly reactive and tends to form compounds with other elements, making it more difficult to detect on its own.
