Musings on a Patch of Sunlight

We are creatures of the sun. We seek out solar spaces — places of warmth and light, though they are fleeting in Minnesota’s late October days. I share my spot of radiance with lady bugs, a meadow hawk dragonfly, a butterfly, bumblebees and a hardy green bee. They soak up energy to power their flight muscles, and I to relax sore back muscles. I revel in this gentle warmth and comfort of a sort I won’t feel again until next spring. 

These solar rays travel 93 million miles (150 million kms) in approximately eight minutes and fuel most of life on Earth. Specialized green plant cells called chloroplasts capture sunlight and transform it into glucose to power a plant’s existence. This converted solar energy is transferred to all creatures who eat the plants, and, in turn, to all who eat the creatures.

We are the stuff of stars, our atoms born in the fusion furnace of some sun, who knows where or when. Scientists believe that most hydrogen and helium atoms were produced during the Big Bang about 13.8 billion years ago. As stars began to “burn” and move through their life cycle, the hotter, denser stars produced heavier elements needed for life, such as carbon, nitrogen and oxygen. The heaviest elements (anything greater than iron) were generated during supernovae, when old, very large, heavy burning stars collapsed and exploded, spewing out elements into the universe to be used again.

I like to ponder these mysteries of creation and connection, of where our atoms have been and will someday be after my time. What better place to reflect than within a warm pocket of sunlight shared with a few earthly companions?

November Moonrise

I miss the long, light days of summer with their extended periods of predawn and dusky twilight.  But, if there’s an advantage to the lengthy winter nights, it is the beauty and greater visibility of the moon and constellations.  The sun’s lower angle allows the moon to be visible during some daylight hours of the winter months.  The planet Venus also is visible high on the southern horizon in the late afternoon and early evening, and is referred to as the “evening star”.

The November moon rises in mid-afternoon.
