A Sense of Perspective

Every now and then, usually when something like politics or racism or injustice or terrorism or whatever else gets nasty, I find it helpful to get a dose of perspective. Thanks to ESO’s VISTA telescope, we have THIS:

It may not look like much at first, until you realize that those points of light are not stars, but whole galaxies. Process that for a minute: you’re looking at over 200,000 galaxies, each one with anywhere from 100,000,000,000 to 300,000,000,000 stars.

Oh, and according to BadAstronomer’s post about this deep-field image, this is only a 1.2 x 1.5 degree patch of sky. That means those 60,000,000,000,000,000 (sixty quadrillion) suns are in just approximately 0.004% of the observable area of the sky. And that’s just what we can see with our current instruments and given where we are in the universe. (You can get the full image from ESO.)


Feeling humble yet? This is really why we do science and exploration.

By expanding the frontiers of what is possible, we move beyond present constraints to worldly solutions. By exploring, we discover more about ourselves, where we came from, and where we could be going. In doing the hardest things imaginable, we develop systems and methods and materials and technologies that rain down into all areas of human life.

And by always striving to look upward at the immensity of the beauty around us, we are constantly humbled into looking inward at how we can make our speck of the universe a better place for our fellow human beings.

If I ever find myself caught up in the mundane, wound up about something petty, or angry at someone or something else, despairing for humanity, or wondering why I should keep striving against something difficult… this is among the set of pictures I look at.

It’s good to keep a sense of perspective.
