Searching for Life, Mindful of Lyfe's Possibilities

Area of Science:

• Astrobiology and the search for extraterrestrial life.
• Interplanetary missions and telescope development.
• Scientific standards for biosignature detection.

Background:

• The search for life beyond Earth is advancing rapidly.
• Interpreting evidence for extraterrestrial life requires caution.
• Current biosignature detection standards need refinement.

Purpose of the Study:

• To emphasize the interconnectedness of life detection with definitions of life, its origins, and habitability.
• To advocate for integrated research across astrobiological frontiers.
• To propose a new framework for assessing habitability, termed 'genesity'.

Main Methods:

• This perspective piece reviews current astrobiological research and proposes a conceptual framework.
• It highlights the need to integrate studies on the definition of life, origin of life, and habitability.
• Introduces the concept of 'genesity' as an expanded measure of habitability.

Main Results:

• Life detection is intrinsically linked to our understanding of life, its origins, and habitability.
• These foundational questions are often undervalued in biosignature research.
• A more inclusive approach to habitability, 'genesity,' is proposed.

Conclusions:

• Astrobiological research must advance interconnected questions of life, origins, and habitability in unison.
• The proposed concept of 'genesity' offers a broader perspective on habitability for detecting diverse life forms.
• Adopting an integrated approach will enhance the rigor and inclusivity of the search for extraterrestrial life.
