The more we learn, the more we realise we have yet to learn.  For years, astronomers speculated about planets outside our own solar system, called exoplanets, but none had been discovered.  Then in 1992, two planets were discovered orbiting the pulsar PSR 1257+12.  Once the first were found, there was an explosion of discovery, and since that time over 3,400 have been confirmed.  The unknown became known, opening the door for new discoveries, theories and understanding about our physical universe.  Still today, previously unknown species or insects, birds and mammals are being discovered, though they knew about themselves all along…

PS:  And speaking of the exploration of space:  On this day in 1969, the Apollo 11 crew returned from the moon to Earth… and had to fill out a customs declaration form just like all the rest of us!
