Pale Blue Dot
Yesterday,
NASA released this compelling photo of our own
planet, taken two weeks ago by the Mars Global
Surveyor probe currently circling the Red Planet.
The space agency billed the photo as "the first
portrait of Earth taken from Mars." It certainly is
awe-inspiring to see just how tiny we are in the
grand scheme. But for such perspective, there has
been no greater image than Voyager's last long look
back at our planet, four billion miles out, before
it turned its back on us and left the solar system
in 1990. This famous image (see below), showing
Earth as a mere speck caught in a beam of sunlight,
illustrates just how fragile and alone we really
are. The image inspired astronomer-philosopher Carl
Sagan to write his book "Pale Blue Dot," and to
give the speech excerpted below at Cornell
University in 1994. His powerful words brilliantly
encapsulate the humbling power of this image.
- We
succeeded in taking that picture [from deep
space], and, if you look at it, you see a
dot. That's here. That's home. That's us. On it,
everyone you ever heard of, every human being
who ever lived, lived out their lives. The
aggregate of all our joys and sufferings,
thousands of confident religions, ideologies and
economic doctrines, every hunter and forager,
every hero and coward, every creator and
destroyer of civilizations, every king and
peasant, every young couple in love, every
hopeful child, every mother and father, every
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 in
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 the dot on scarcely distinguishable
inhabitants of some other corner of the dot. 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 obscurityin all this
vastnessthere is no hint that help will
come from elsewhere to save us from ourselves.
It is up to us. It's been said that astronomy is
a humbling, and I might add, a
character-building experience. To my mind, 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 and
compassionately with one another and to preserve
and cherish that pale blue dot, the only home
we've ever known.
