Most of our lives, we are focused on what is in front of us. When we gaze at the stars, we reflect on our place in the universe. An eclipse event brings that reflection into more concrete terms.

Two types of eclipses are visible from Earth, an eclipse of the moon and an eclipse of the sun. A lunar eclipse occurs when the Earth moves between the sun and the moon, blocking the sunlight that is normally reflected by the moon. A solar eclipse occurs when the moon is directly between the sun and the Earth, casting a shadow on the Earth.

Learn more about the different types of lunar and solar eclipses and how they occur.

    People in the past carved petroglyphs and painted pictographs to mark the cycle of the sun, moon, and stars; solstices; and the changing seasons. They tracked time by creating solar calendars that interacted with light and shadow as the sun moved across the sky. When unique astronomical events took place, they documented the moment in stone. Learn more about the purpose for these images.
