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.

Keith's note: This coming week I will be at the Astrobiology Science Conference (AbSciCon). I will be tweeting about the meeting from @NASAWatch and @Astrobiology and posting updates at astrobiology.com. AbSciCon Sessions will be streamed live at http://astrobiology.nasa.gov/livestream

Day Two of Breakthrough Discuss opened with Michaël Gillon describing the discovery of TRAPPIST-1, which has seven temperate planets, including three in the habitable zone.

The first day of Breakthrough Discuss 2017 explored planets around nearby stars and their potential for life. Charles Alcock opened the conference with the statement that, "The far-fetched ideas of today are the discoveries of tomorrow," and Peter Michelson emphasized that the last century of scientific investigation has transformed questions about origins from the realm of metaphysics to a place where they can be investigated observationally.

Breakthrough Listen - the initiative to find signs of intelligent life in the universe - has released its 11 events ranked highest for significance as well as summary data analysis results.

A new method for analyzing the chemical composition of stars may help scientists winnow the search for Earth 2.0.

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.

The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other planets could be billions of years older than ours.

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