What Is A Biosignature In Astrobiology? Have you ever wondered how scientists identify signs of life on other planets and moons? In this informative video, we'll explain everything you need to know about biosignatures in astrobiology. We'll start by defining what a biosignature is and what types of signals or clues scientists look for when searching for extraterrestrial life. You'll learn about different forms of biosignatures, including chemical markers like organic molecules and isotopic ratios, as well as physical features such as fossils and microbial mats. We'll also discuss the significance of atmospheric gases like oxygen and methane, which can suggest biological activity.

The video will cover how space missions, like rovers on Mars or telescopic observations of distant planets, are designed to detect these signs. We'll explain the challenges scientists face in distinguishing between biological and non-biological sources and the methods they use to confirm potential signs of life. Whether you're interested in space exploration, planetary science, or the search for life beyond Earth, this video provides a clear overview of how biosignatures guide scientists in their quest to answer one of humanity’s biggest questions: Are we alone in the universe?
