Our Cosmic Ancestors
Week of Dec. 21-27, 2014
We are made of star stuff.
How many times over the years have we read or heard this phrase, but never stopped long enough to consider its true significance?
Well, let's do so now.
When the universe we know came into being some 14 billion years ago, there existed little more than hydrogen. But look around you; today we see everything from silicon in our computer chips, aluminum in our baking pans and chlorine in our swimming pools. So where did it all come from?
Amazingly, it came from the stars; for these are the chemical factories in which everything we know was created eons ago.
And not only the external world, but our internal selves as well. The oxygen we breathe, the calcium in our bones, the carbon in our DNA, all were forged deep within distant and ancient stars and blasted into space during a final act of stellar death. In fact, the very iron in our blood was the trigger for at least one supermassive star's explosion somewhere and sometime in the distant past.
After wafting through the cosmos for who knows how long, this stellar ash loaded with heavy elements merged with and enriched the already-existing hydrogen clouds, where it spurred the birth of new stars and planetary systems. And, in at least one place, life itself.
Yes we are made of star stuff — a truly remarkable concept to ponder while standing under the starry night.
In our case, it all came together billions of years ago, but it's not difficult to find places where similar activity is occurring today.
We can now see Orion making its grand entrance onto the stellar stage in the east after dark. Two stars — Betelgeuse and Bellatrix — mark the shoulders of the celestial hunter. Saiph and Rigel form his knees. In his mid-section appear three stars in a nearly straight line — Alnitak, Alnilam and Mintaka — that trace his belt. And below hangs a sword that appears as a smudge of light known to astronomers as M42: the Great Orion Nebula.
Even a small backyard telescope under a dark night sky can show us the delicate structure of this stellar nursery, and the four tightly-packed young stars near its center that illuminate it from within.
It is from a similar place that we can trace our own origins. Exactly where that was, of course, we cannot say, but we know that the materials out of which we are made came from somewhere "out there." Perhaps even more profound is that our species has evolved the intelligence and technology to ponder this remarkable fact.
When we gaze upon the stars at night we are viewing our ancient ancestors and, to me, this makes the starry heavens — and the phenomenon we call life — even more remarkable and precious.
It is from under this canopy of glittering stars that I wish all of my readers a happy and safe holiday season — in whichever way you wish to celebrate — and an exciting and star-filled 2015.
I promise there will be much to see!
