During its 221st meeting, the American Astronomical Society
announced the identification of 17,000,000,000 Earth-sized planets in our
galaxy. That means that 17% of the stars in our galaxy have a planet up to 1.25
times the size of Earth in an orbit lasting 85 days or less. Ours, of course is
not the only galaxy. Since even the most powerful of our instruments can view
only a fraction of the universe, no one knows how many galaxies exist.
Astronomers and cosmologists estimate that there are 100 to 200 billion
galaxies, but a German supercomputer simulation recently posited the existence
of 500 billion. There may be a galaxy out there for every star in the Milky
Way, and each galaxy contains hundreds of billions of stars.
In other words, we're just a speck of dust in our 13.8
billion years old universe. Yet, what a wonderful speck we are and how precious
is the glimmering blue orb we inhabit. Nothing could be rarer than our
planetary home, and each one of its inhabitants is unique. Do we need more
motivation to receive the gift of life with gratitude and pursue it with
courage? On the worst of days, despite the odds, we exist. None of us knows how
long we will live, but whether for a moment or a century, life is miraculous.
How can we know that and not feel grateful and not want to revere, protect,
sustain, and preserve the miracle that we are and have?
Add this to the pondering. On April 18, NASA announced that
its Kepler space telescope had discovered three exoplanets (An exoplanet is a
planet outside our solar system.) that may have the capacity to support life.
One of them, Kepler-62f, is 1.4 times bigger than Earth and circles a star
smaller and dimmer than our sun. The neighboring Kepler-62e is 1.6 times larger
than Earth. Both of them orbit their star in the "habitable zone,"
the appropriate range of distances where liquid water can exist on an
exo/planet's surface. William Borucki, Principal Investigator at NASA's Ames
Research Center, declared that these orbs "look very good as possibilities
for looking for life."
We may never have the ability to meet them face-to-face, but
we may have kissing-cousin creatures somewhere in the vastness of all that is.
Only 4.9% of all that is consists of ordinary matter. The rest is dark matter
and dark energy. Yet, that 4.9% suffices for our extraordinary world and lives
and possibly other worlds and lives as well. Far from making us less unique,
that makes us more extraordinary and deepens my sense of awe. Despite the odds,
life finds a way. Not everyone calls the reason for that God, but we do. God's
reach extends far beyond us. As a part of God, our capacity for relationships
exceeds our imaginations.
There may be a galaxy out there for every star in the Milky Way,
and each galaxy contains hundreds of billions of stars. We inhabit a planet
just the right distance from one of those hundreds of billions of stars to make
life possible. That ought to make us feel profoundly grateful for our lives and
fill us with desire to do something worthwhile with our lives. In Paul's words,
"Rejoice always." In the words of our baptismal liturgy, "Obey
Jesus' word and show his love."
