Ever since early humans first looked skyward and imagined the stars as distant campfires, humanity has wondered if we are alone in the Universe. The ancient Greeks argued against our home planet being the only cradle for life, but lacked the technology to prove their beliefs. In the late 20th century, the near-simultaneous discoveries of the possible remains of bacterial life in a Martian meteorite, and the first planets orbiting other stars, brought the question of the existence of life beyond the Earth to the forefront of scientific endeavor. In the 21st century, the new field of Astrobiology harnesses the required technological and scientific capability to seriously address this ancient and fundamental question.

Astrobiology is the study of life in the universe. The search for life beyond the Earth requires an understanding of life, and the nature of the environments that support it, as well as planetary, planetary system and stellar processes.   To provide this understanding, astrobiology combines the knowledge and techniques from many fields, including astronomy, biology, chemistry, geology, atmospheric science, oceanography and aeronautical engineering. Astrobiologists can work alone on particular scientific questions, but often astrobiologists from different scientific disciplines work together to examine complex questions that no one field can answer alone. These questions cover topics such as: Graduate student Michael Kipp speaking to Lakewood High School students.

What is Happening in the Field of Astrobiology?

While astrobiology is a relatively young field, it has a secure and promising future. Astrobiology research has a significant impact on how agencies such as the National Aeronautics and Space Administration (NASA) and the European Space Agency plan for current and future space missions. For example, many recent missions have focused on exploring worlds in our own solar system for signs of past, present or the precursors of life, including Mars (Phoenix , Pathfinder , Global Surveyor, and others) and Titan (Cassini-Huygens ). At the same time, significant advances and investments in telescope technology (Kepler,  James Webb Space Telescope) have allowed researchers to begin planning and searching for habitable planets outside our solar system.

In the United States, NASA and the NASA Astrobiology Institute (NAI) are leading policy makers and funders in astrobiology. An overview of the research goals and objectives they have articulated can be found in the NASA Astrobiology Roadmap. Internationally, astrobiology networks and institutes have been established in Europe, Australia, Canada, Mexico and South America, including the Centro de Astrobiologia  in Spain, the Nordic Network of Astrobiology Graduate Schools, and the Australian Center for Astrobiology.

The University of Washington and Astrobiology

As the field of astrobiology has grown, there has been an increased need to train the next generation of astrobiology researchers and educators. This is why, in 1999, the University of Washington established its Astrobiology Program (UWAB) – an interdisciplinary education and research program dedicated to advancing our understanding of current astrobiology issues and training the astrobiologists of tomorrow. UWAB is home to many cutting edge research projects, an internationally recognized graduate program, and an ever-growing collection of teaching-and-learning resources for astrobiologists and astrobiology enthusiasts of all levels.

How Can I Learn More about Astrobiology?

Here at UWAB, our dedicated Education & Outreach team continues to develop a library of materials for audiences of all ages and experience levels, ranging from curious amateurs to university-level instructors and students.
