Recently, there's been a spike in UFO sightings — officially UAP, or Unidentified Aerial Phenomena — all over the world and nobody seems to know why or what the objects we're seeing might be.
What most people remember about Apollo 14 is Alan Shepard hitting golf balls on the moon. But on the same mission, command module pilot Stuart Roosa took seeds to space and back and now they're beautiful trees on Earth.
