A recent study found anecdotal evidence that our increased exposure to political strife is having a negative effect on our mental health, resulting in “frayed personal relationships, compromised emotional stability, and even physical problems.” So what else is new? I, for one, am getting sick and tired of writing about politics. I see it as a service, and personally cathartic. But still a stressful task.
So for once I’ll skip a political column and try something completely different. Pretty much lost in Donald Trump’s post-acquittal victory lap, NASA gave us all a Valentine’s gift. It reprocessed and re-released an image recorded thirty years ago, February 14, 1990, by Voyager 1, at the time 3.7 billion miles from the Sun.
On that date Voyager 1 was headed out of our solar system on a flight that began in 1977. It had already imaged Jupiter and Saturn and was now exploring Neptune. Carl Sagan, the great scientist and science evangelist was a member of the Voyager imaging team at NASA’s Jet Propulsion Laboratory. The plan, following the Neptune encounter, was to turn off Voyager’s cameras to save power for its other instruments as it traveled beyond the outermost planets. Sagan suggested before they did that, that they turn the spacecraft around, point it toward Earth, and see what it saw.
The newly released image has been reprocessed and is sharper and brighter than the version released thirty years ago. Still as you can see, Earth is the tiniest dot within a scattered ray of sunlight.
For everyone who is stressed by humanity’s current state of affairs I suggest you take a break, stop, look and contemplate how insignificant these problems should be in the grand scheme of the universe. Sagan said it best:
Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there–on a mote of dust suspended in a sunbeam.The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.
