90 light years is so close

By now you may have heard of the discovery of a new planetary system that looks a whole lot like our own. It’s 90 light years away, but as a wise man once said, “that’s peanuts to space.” Seriously, 90 light years is the kind of distance we’ll be able to travel in a few months (relative) once we get the basics of interstellar flight taken care of.

Even better, seeing a solar system like our own so close to home makes it even more likely that we’ll find one with Earth-like life sometime fairly soon. That’s why I like reading this:

ESA is leading the way with its Darwin mission to analyse the atmospheric composition of Earth-like planets. This flotilla of six space telescopes will launch in around 2014.

How very 21st century!

A Pale Blue Blob

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors, so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light.”
