A lunar eclipse and a cosmic perspective

February 20, 2008

lunareclipse.jpgThe moon is in totality as I write. It’s beautiful, a fleeting mask on a face that has looked down on Earth for billions of years.

I can’t help but think of the words of one of my heroes, Carolyn Porco, who currently leads the imaging team for Cassini:

To know that we can know so much about our Solar System and about our cosmos, for me, makes life meaningful. It’s very much like being in love. It’s very much that kind of relationship where you want to know more and you want to be one with the person you’re in love with or topic you’re studying. It’s a connection… it’s really a connection, and for me it’s… it’s like being allowed a glimpse of the miraculous.

Link: How Big Are We? (Updated 8/29/06)

Here are a series of pictures that show the relative sizes of our local planets and stars. If you’ve ever considered yourself an infinitesimal dot in a vast universe, this will give you some small idea how right you are! Keep in mind when viewing the images that you’re seeing only objects from our local galactic neighborhood, and that it would be even more mind-blowing if we included some sense of relative distances!

Update 8/29/06: Here is another page with the same theme, but limited to the solar system. There are three wonderful photographs, and some thoughtful writing and reader comments as well.
