Julius Berkowski captured the first-ever useful image of a solar eclipse at Prussia’s Royal Observatory. Nevertheless, eclipses have always happened on Earth—even before there were any humans. Humans have reacted to and understood these amazing astronomical phenomena in diverse ways over time.

The eclipse that is oldest in human history occurred on November 30, 3340 B.C.E. The last one happened in 2017. A total eclipse is when the moon completely obscures the Sun’s face as it moves between the Earth and the Sun. During an eclipse, the sky darkens, appearing as though it is dawning or dusk, but you should never stare straight at it.
