“Heaven is under our feet as well as over our heads.”
—Henry David Thoreau
NASA has been engaged for many years in the search for exoplanets, with a wide variety of highly sophisticated and expensive instruments. If you care to do a bit of reading, check out these links:
Exoplanets orbit stars outside our solar system. Scientists have discovered thousands of them to date, and the numbers continue to grow. Perhaps the biggest question is how many are actually out there, and more importantly, how many have life, or could sustain life?
Although it is guesstimated that there are trillions of exoplanets, and that the sheer number of them adds to the potential that they could harbor life, they are all too far away to visit – even in multiple lifetimes.
How and in what ways can and will you honor and cherish our beautiful planet? What can you do to leave it far better than you found it, for the sake of the earthlings and space travelers of the future?
