Developments in artificial intelligence may help us to predict the probability of life on other planets, according to new work by a team based at Plymouth University.

The selection of optimal targets in the search for life represents a highly important strategic issue. In this paper, we evaluate the relative benefits of searching for life around a potentially habitable planet orbiting a star of arbitrary mass relative to a Sun-like star.

SETI is Part of Astrobiology

"Traditional SETI is not part of astrobiology" declares the NASA Astrobiology Strategy 2015 document. This is incorrect.

Astrobiology is a scientific discipline that studies life in the Universe. We call it a discipline and not a science because some authors have cast doubts over its epistemological status by calling it 'a science without an object of study'.

Was this the earliest TV mention of "astrobiology"? A scene from the original Star Trek episode "Return To Tomorrow" which first aired on 9 February 1968:

KIRK: "Who are you?"
MULHALL: "Doctor Ann Mulhall, Astrobiology"

Contrary to what NASA may want you to think, the word "Astrobiology" was used decades before NASA began using it to describe the study of extraterrestrial life.

This book "Astrobiology" - "Aстробиология" was published (in Russian) in 1953 in the USSR.

The photos below illustrate the topics that the book covered.

I am currently attending the Astrobiology Science Conference where the world's astrobiologists all meet to showcase their results and share ideas. There was a time, barely 20 years ago, when there were no astrobiologists. I was one of the lucky people to be present as this amazing 21st century discipline came into existence.

Understanding the limits on what microbial life can endure is important for preventing contamination of the Red Planet with terrestrial microbes when our human and robotic explorers arrive.

Why are we now? We know that the universe is roughly 14 billion years old, and that someday it is likely to end -- perhaps because of a Big Freeze, Big Rip or Big Crunch.

Astrobiology Primer v2.0 Released

The long awaited second edition of the Astrobiology Primer is now published in the journal Astrobiology.

If the origin of life is common on other worlds, the universe should be a cosmic zoo full of complex multicellular organisms.

On The Habitability of Our Universe

Is life most likely to emerge at the present cosmic time near a star like the Sun? We consider the habitability of the Universe throughout cosmic history, and conservatively restrict our attention to the context of "life as we know it" and the standard cosmological model, LCDM.

The Astrobiology Program of NASA's Science Mission Directorate (SMD) is joining with the Directorate for Biological Sciences (BIO) and the Directorate of Geosciences (GEO) of the National Science Foundation to sponsor an "Ideas Lab" activity on the Origins of Life.

Are humans unique and alone in the vast universe? This question-- summed up in the famous Drake equation--has for a half-century been one of the most intractable and uncertain in science.

The first scientific Roadmap for European Astrobiology was published on March 21st. This strategic landmark for European astrobiology has been produced through the European Commission-funded AstRoMap project (2013-2015).

In a harsh environment with very little water and intense ultraviolet radiation, most life in the extreme Atacama Desert in Chile exists as microbial colonies underground or inside rocks.

The Baruch S. Blumberg NASA/Library of Congress Astrobiology Program establishes a focus in the nation's capital for the exploration of issues surrounding life's future in the universe, for humans and other species, on Earth and beyond.

If you were looking for the signatures of life on another world, you would want to take something small and portable with you.

Over the past two years 800 members of the astrobiology community have contributed, through in person meetings, white papers, a series of webinars and reviews, to define a new strategy for the next decade of astrobiology research. Mary Voytek, the Senior Scientist for Astrobiology, and Michael New, the Astrobiology Discipline Scientist, described the goal of the endeavor to create an "inspirational and aspirational" document. The strategy will replace the 2008 Astrobiology Roadmap.
