Exoplanet Radio Ep. 42: How Long Will Life on Earth Last?

From October 9, 2013.


Nothing lasts forever, stars live and die over the course of
hundreds of millions to billions, and in the case of red dwarf
stars, trillions of years. Planets are born from the remnants of
their parent stars and die over a shorter timescale. Life on
those planets, if it exists, is presumed to be shorter still,
governed entirely by the environments provided by the combination
of the star and planetary characteristics. How long life lasts
there ultimately depends on how long the star lives and how it
dies.


 


Using our solar system as an example, since we know life arose
here, how long will it last?  Astronomers think they have an
answer.
