One of our space probes has found that Titan, Saturn's largest moon, looks just like Earth.

It's got lakes and rivers. And rain.

The Times says that no other "planet" in our solar system looks as similar to our humble home.

Except that the blissful precipitation on Titan, bigger than Mercury, that Cassini found is, well, methane. That's cos it's bastard freezing.

So not like Earth at all, really. More like earth. On Saturn.

An unlikely home for life today, as it is too cold, but this could change in four billion years, when the Sun swells to become a red giant. Conditions could then become just right for the emergence of life.

Just when the neighbourhood is about to go up in a galactic blaze of hydrogen. You can just imagine the first words of the things that just limped out of the oceans: Bugger.
