Subject: Solar Systems More Habitable Than Ours


Hello List,

Looks like the odds given by Drake Equation are increasing yet
again:

[Quotation Begins]

"Search for life suggests solar systems more habitable than ours
Of the eight solar twins they've studied so far, seven appear to
contain much more thorium than our sun - which suggests that any
planets orbiting those stars probably contain more thorium, too.
That, in turn, means that the interior of the planets are
probably warmer than ours."

[Quotation Ends]

It's worth recalling, as reminded by Sagan and others, if it
weren't for carbon dioxide and other greenhouse gases, Earth
would be solid ice from pole to pole - 'Snowball Earth'  -
because we're actually just outside of the local Goldilocks
zone.


Cheers
