Is there life beyond Earth?

Caleb Scharf works in the fields of exoplanetary science and astrobiology, and writes extensively about science for a popular audience. Exoplanetary science is devoted to the discovery and characterization of planets around other stars, and understanding the formation, histories, and properties of these planets. One ultimate goal of this research is to find planets that could harbor recognizable life, and to detect the presence of that life—an effort that falls under the banner of astrobiology.
