I will discuss the
question "Are We Alone?" and review progress in trying
to figure out what this question means. Who is "we"?
Homo sapiens? "intelligent life"? Life in general? What
is life? And what does life have to do with astronomy?
As we learn more about the origin and evolution of the
universe and about the prerequisites for the emergence
of life, the connections between cosmology and biology
are becoming more obvious and more quantifiable. Where
and when in the universe did the first molecules form?
Where and when did the first stars and terrestrial
planets form? Where is the liquid water in the universe?
Since life emerged early in the history of the Earth,
does that mean that life is common in the universe? I
will focus on the big picture and summarize our
knowledge and speculations about cosmobiology and the
astronomical origin(s?) of life in the universe.
Charles H. Lineweaver is the coordinator of the
Australian National University’s Planetary Science
Institute and holds a joint appointment as an associate
professor in the Research School of Astronomy and
Astrophysics and the Research School of Earth Sciences.
He obtained an undergraduate degree in physics from
Ludwig Maximillians Universitat, Munich, Germany and a
PhD in astrophysics from the University of California at
Berkeley.
He was a member of the COBE satellite team, led by
George Smoot (2006 Physics Nobel Prize), that discovered
the temperature fluctuations in the cosmic microwave
background. Before his appointment at ANU, he held
post-doctoral positions at Strasbourg Observatory and
the University of New South Wales where he taught one of
the most popular general studies courses "Are We Alone?"
His research areas include cosmology (determination
of the age and composition of the universe)
exoplanetology (the statistical analysis of exoplanets)
and astrobiology ( using our new knowledge of cosmology
to constrain life in the Universe). His research has
been published in Science, Nature, the Astrophysical
Journal, Astrobiology, Scientific American, American
Journal of Physics, and Microbiology Australia.
He is the son of a high school biology teacher and
has lived in or travelled through 65 countries, has
spoken 4 languages semi-fluently at one time or another,
and was a semi-professional soccer player in Germany
