Here's some food for thought: The distance between Tahiti, where the explorer James Cook observed the Transit of Venus in June, 1769 and Hawaii, where +NASA telescopes on Hawaii's Mauna Loa will observe the same phenomenon later today, can be measured by years and miles, or by humanity’s quest for knowledge of the universe. Where will that quest lead us to by 2117, the next time our neighboring planet passes directly between our +Fragile Oasis and the face of our shared Sun?
