Eclipses have inspired myths, predictions and scientific discoveries. The total solar eclipse occurring on April 8 provides a once-in-a-lifetime opportunity to engage with science and the cosmos.
Solar eclipses happen because of a few factors, including the Moon’s size and distance from the Sun.

Many people will see a dazzling eclipse this April, but these events are possible only because of the sizes and precise distances between Earth, the Moon and the Sun.
The surface of Mars is cold, dry and rocky.
