Teaching Science with iOS — From Macro to Micro — Part I

When we peer out at the night sky on a clear, moonless night, we see thousands of individual stars — millions if you count galaxies mixed into the field of view. Look at your finger and you'll see the intricate swirls and folds that make up your fingerprint. In both cases, we only see the surface of vast processes that bend light and time, or those that create and sustain life. Our human senses aren’t sufficient to perceive the magnitude of the activity, nor the structure, that defines the universe.

To paraphrase Carl Sagan's famous remark, there are billions upon billions of stars and other sparkly things out there in the night skies. Gazing into the heavens on a clear night can be a mystical experience, but the real magic occurs when you understand what you're looking at.


Astronomy began thousands of years ago when shepherds in the field gazed up at the sky and saw the outlines of objects and mythical beings traced by patterns of stars. As time passed and technology evolved, our knowledge of the sky improved. But to this day, we still cling to the same 88 constellations envisioned by those ancient shepherds on long ago sleepless nights.
