Adding to the excitement on eclipse night … this eclipse will happen on the same night that Earth is passing between the sun and Mars, placing Mars at opposition in our sky. In one of the sky’s wonderful coincidences, the Mars oppositionhappens on July 27, too. It’s not just any Mars opposition, but the best Mars opposition since 2003. Mars is very bright and red throughout July and August, 2018. But eclipse night will be a very special night. On July 27, the sun, Earth and moon are aligned – placing the moon opposite the sun in our sky – producing an eclipse as Earth’s shadow falls on the moon’s face. On the same night, the sun, Earth and Mars are also aligned, bringing Mars also opposite the sun in our sky, just like the full moon. That’s fun to think about, but there’s more for those who plan to observe the eclipse.
