What’s so important about a solar eclipse?

Today, NASA scientists still study eclipses to make new discoveries about the Sun, Earth, and our space environment.

The moon is fully in Earth’s shadow. At the same time, a little bit of light from Earth’s sunrises and sunsets (on the disk of the planet) falls on the surface of the moon. Because the light waves are stretched out, they look red. When this red light strikes the moon’s surface, it also appears red.

Is there any oxygen on the moon?

The Moon’s top layer of rocks, known as regolith, has abundant oxygen, and can be extracted to support human life. This oxygen on the Moon’s surface, however, is not in gaseous form yet, but researchers are exploring ways to extract usable oxygen from the regolith.
