Even within our solar system, life elsewhere can't be ruled out. It's clear
that Mars at one time might have been able to support it. There is also some
evidence of appropriate conditions on some of the moons of Jupiter & Saturn.

The Universe is almost entirely devoid of anything! It is very empty. That does
not mean to say that life is uncommon in the universe where life can be
supported - who knows.
I too would recommend this series to those that can see it.[ Reply to This | Parent | # ]

Actually in "Ep 1. What Is Life?" I think he shows
that "the
emergence
of life might be an inevitable consequence
of the laws of physics".
Ep 1. What Is Life?
In this episode Brian Cox visits
South East
Asia's 'Ring of Fire'. In the world's most volcanic region
he
explores the thin line that separates the living from the
dead and poses that
most enduring of questions: what is
life? The traditional answer is one that
invokes the
supernatural, as seen at the annual Day of the Dead
celebrations
in the Philippine highlands. Brian sets out to
offer an alternative answer: one
bound up in the flow of
energy through the universe.
On the edge of
Taal Volcano lake, Brian demonstrates how the
first spark of life may have
arisen. Here, heat energy from
the inner Earth forces its way to the surface
and changes
its chemistry, just as it did in our planet's infancy. It is
now
believed that these chemical changes set up a source of
energy from which life
first emerged.
Today, virtually all derives its energy from the Sun.
But
there's a paradox to this as according to the laws of
physics energy can
neither be created nor destroyed. So life
doesn't 'use' energy up. It can't
remove it from the
universe. So how does energy enable living things to
live?
Brian reveals life to be a conduit through which energy in
the
universe passes, just one part in a process that governs
the lifecycle of the
entire Universe. By diverting energy in
the cosmos living things are able to
grow and thrive.
But whilst the flow of energy can explain living
things, it
can't explain how life has endured for more than three
billion
years. So Brian meets an animal in the Borneo
rainforest that holds the key to
how life persists - the
orangutan. Ninety seven per cent of our DNA is shared
with
orangutans. That shared heritage reveals a profound
conclusion: that DNA
is a record of the evolution of life on
Earth, one that connects us to
everything alive today and
that has ever lived.
So life isn't really a
thing. It's a chemical process, a way
of tapping into the energy flowing
through the Universe and
transmitting it from generation to generation through
the
elegant chemistry of DNA. Far from demanding a mystical
explanation, the
emergence of life might be an inevitable
consequence of the laws of physics.
