Subject: Anyone Care To Re-Work The Drake Equation?


Hello List,

Just happened to notice that several factors in the famous
equation seem to have increased, sometimes ten times or more, in
last decade or so - here's three instances -

Exactly how many stars are in the Milky Way?

Most likely mass is 700 billion... divide this by the average
mass of a star... say 0.3 solar masses, to get an estimate for
the number of stars - which is well into the trillions!"

"Meyer and his colleagues found that at least 20 percent, and
possibly as many as 60 percent, of stars similar to the sun are
candidates for forming rocky planets."

Like Our Own

"You could call it luck, but I think it might just mean that
these systems are common throughout our galaxy."

Anyone got a copy of the equation who'd like to re-do the
arithmetic?


Cheers
