The Pale Blue Dot

May 7, 2025

To us Earth is home. Home to 7 continents, 5 oceans, over 8 billion humans, and almost 8 million other species of plants, animals and other organisms. But when Voyager I looked back at Earth from a distance of 6 billion kilometres, it saw a "pale blue dot" suspended in a sunbeam!

We know that Earth is just a small planet among 8 others, revolving around a small star, which itself is just one among billions of others in our galaxy. And yet, it is both fascinating, and to some extent alarming to realise that everything that we have ever known, every person who ever lived, every civilization which appeared and ended, every event, every emotion, all the history that we know of, all of our present developments, and sociopolitical drama, occurrs on this single pixel in an image, and that too for a small instant of time in its long history of existence.

That is the power of Astronomy.

It is not just another subject of sciences. Astronomy not just links various fields of science, mathematics and technology, but is a medium to take us back to our roots and help us connect with the universe. It reminds us of our fragile existence, and provides an opportunity to get rid of our egoes and rise above our false façade. This realisation, which comes naturally to astronomy enthusiasts makes them humble, empathetic, and socially responsible towards their fellow humans and natural environment alike. And as Carl Sagan rightly said, "Astronomy is a humbling and character building experience. There is perhaps no better demonstration of the folly of human conceits."
