A supermoon occurs when a full moon coincides with perigee, its closest approach to Earth.

Are solar eclipses safe to view with the naked eye?

No, viewing a solar eclipse without proper protection can cause serious eye damage.

Why does the Moon appear red during a lunar eclipse?

The Moon appears red during a lunar eclipse due to Rayleigh scattering of sunlight through the Earth's atmosphere.
