How did life originate and diversify on Earth?
How does life co-evolve with a planet?
Does life exist beyond Earth?
What is the future of life on Earth and its capacity to move beyond the home planet?

However, astrobiology is merely a way to think about living things in their astronomical or cosmic context, to address questions such as the origin of life or the existence of life elsewhere that requires linking
biology with other fields such as planetary sciences or astronomy.
