More Planets Could Harbour Life

The important thing is not to get too excited at this time. Just because the model predicts that somewhere is capable of supporting life doesn't mean that any of it is developed and synchronised with this globe's life to such an extent that a signal can be received, interpreted correctly and a reply sent in a meaningful timescale given the distances involved. What any model does do, though, is narrow the possibilities and increase the chances.

It is probable that our close neighbour Mars was capable of supporting life at some time in its past. The search for evidence to support the conjecture continues with some supporting images and video coming from there recently with a quality that would have been unimaginable four decades ago.

The search for intelligent life on this planet is also underway, however it has only had enough in the way of long-range emissions itself for, oh, say a century or so - a tiny part of the time that life has existed here - and it hasn't knowingly responded to any incoming traffic. What if the other planet's life had been scanning this one a couple of hundred years ago, had drawn a blank, and since moved off to look elsewhere <rhetorical question> _{(conceptulaised populated UFOs are to be disregarded in this illustration)}?

There. That's better.

Yeah very improbable....he he he

"The search for intelligent life on this planet is also underway,"

Yep. It is. I am still looking.

(Suddenly I feel lonely now.)
