A Multiverse - where our Universe is only one of many - might not be as inhospitable to life as previously thought, according to new research.

The third annual Breakthrough Discuss scientific conference, which will bring together leading astrobiologists, astronomers, engineers, and astrophysicists to advance discussion around recent discoveries of potential life in the Universe and novel ideas for space exploration, will be held on Thursday, April 12 and Friday, April 13, and full sessions will be available for live viewing on YouTube.

The two days of discussions will focus on "Alien Life: Diversity in the Universe," with sessions discussing the search for life in our solar system, possibilities for non-terrain life in the Universe, as well as progress in novel space propulsion. The conference will be live streamed on the Breakthrough Prize's YouTube page. Viewers are encouraged to participate virtually via a chat feature, which will be monitored by a facilitator who will feed questions into the panel discussion sessions.

Arizona State University's School of Earth and Space Exploration recently released new research on its flagship Smart Course, Habitable Worlds, published in the peer-reviewed journal, Astrobiology.

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.
