The Quest for Habitable Worlds: Astrobiology, Exoplanets, and the Challenge of Detecting Life

To the point

Scientists look for life beyond Earth by studying exoplanets with telescopes such as Hubble and Webb, focusing on worlds in the habitable zone where liquid water could exist, while recognizing that diverse planets and potential biosignatures must be interpreted cautiously with context and models using indirect, multidisciplinary approaches since we cannot visit nearby planets.

Life on exoplanets?

The question ‘Are we alone in the Universe?’ has been asked by humankind for centuries. The field of astrobiology seeks to answer this question. By studying the origin, evolution and distribution of life in the Universe, astrobiologists hope to better understand the nature of life and whether it could exist on planets other than Earth.
