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"

Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself.

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.

The search for habitable exoplanets and life beyond the Solar System is one of the most compelling scientific opportunities of our time.

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 AbSciCon Sessions will be streamed live at

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.
