Full Moon 2019 calendar: When is the next Full Moon? What is the Super Blood Wolf Moon?

The Moon transforms into a brooding bloody shade of red during the Eclipse.

The Moon normally illuminates the night sky because it reflects the Sun’s rays.

And the Moon is in total shadow, some light still passes from the Sun through Earth’s atmosphere.

This light is bent toward the moon – an effect called Rayleigh scattering.

Other colours in the spectrum are blocked by our atmosphere, but red wave length tends to make it through.

“The two eclipses I am most looking forward to are the Jan 21 total lunar eclipse, and the July 2 total solar eclipse visible from Chile and Argentina,” said Fred Espenak, retired NASA astrophysicist and eclipse expert.
