Many of us on Earth live in a home with a street address, city, and zip code. But we have another address, which astronomers and astrophysicists refer to as our "cosmic address": Earth, Solar System, Milky Way, Local Group, Virgo Supercluster, the Universe. Consider the vast scales that our cosmic address spans. Understandably, it's hard for our brains to truly imagine it. Our galaxy, The Milky Way, is populated with somewhere between 100-400 billion stars, one of which is our Sun, an average, run-of-the-mill star.

The Apollo space program is the most famous and celebrated in American history, but the first successful landing of men on the moon, during Apollo 11, had complicated roots dating back over a decade; it also involved one of NASA's most infamous tragedies.
