Pale Blue Dot

Last weekend the boys and I went to a planetarium and attended several of the shows offered. One of the presentations, Extreme Planets, explored the possible environments of planets that have already been discovered outside of our solar system.



This and the Live Star Talk by the Planetarium's astronomer were pretty spectacular.

The Rationalist said afterwards,"Watching those shows made me realize how small Earth is and how easily it could be destroyed."

I concurred. Imagining the immensity of space, the vastness of our galaxy and the prospect of billions of other galaxies, it does make a person seem pretty insignificant.  It also makes me think that somewhere out there there has to be at least one other planet with life.

Functionally, it doesn't really matter.  Even if there are thousands of planets with life, they are so far from us that they may as well not exist.  Theoretically, though, how amazing would that be?

My younger brother designs the super versions of these for Skyskan. Very cool job, and I envy him this.
