The Astrobiology Strategy
Astrobiology research sponsored by NASA focuses on three basic questions: How does life begin and evolve? Does life exist elsewhere in the Universe? How do we search for life in the Universe? Over the past 50 years, astrobiologists have uncovered myriad clues to answering these Big Questions.

The cover shows a series of planet-like objects representing disciplines of astrobiology (geology, icy ocean worlds, cellular biology, chemistry molecular biology, etc.) The biology pages feature organisms from bacteria to multicelluar life (humans, trees, etc.). A scientist looks in a microscope while others gather samples from a bubbling hot spring. An underwater vehicle looks at hydrothermal vents beneath the ocean. Stromatolites and fossils of ediacaran biota are also present, as well as molecules like DNA and proteins.](https://science.nasa.gov/wp-content/uploads/2023/07/cover-biology.png?w=4096&format=png)
