On Sept. 18, 1977, NASA's Voyager 1 spacecraft took a photo of Earth and the moon. It was the first time both the Earth and the moon were captured in a single frame. At the time, Voyager 1 was more than 7 million miles away from Earth.

An asteroid has a slight chance of hitting the moon in 2032. Here's what to know about 2024 YR4 and a way to stop that.
