June: First Recorded Lunar Eclipse in North America
A lunar eclipse occurs when a full moon passes through the Earth's shadow. Lunar eclipses, visible to the naked eye, gave astronomers information about the solar system long before telescopes existed. Aristotle even used a lunar eclipse to determine that the Earth is round. The first astronomical event recorded in North America was a lunar eclipse on June 25, 1638.
