Abstract

"Are we alone in the universe?" is the fundamental question of mankind. To search for the life signatures in the universe, there have been a lot of researches and space explorations, especially in our solar system. In this review paper, we introduce the definition and characteristics of the "biosignature". The current situations and future plans for searching for biosignatures in our solar system are reviewed, especially at Venus, Mars, and Ocean Worlds such as Europa and Enceladus where life signatures are more likely to exist than in other places in the solar system. Finally, we discuss the opportunities and strategies for the Korean scientific society to participate in searching for biosignatures in the solar system.
