Total Lunar Eclipse of September 27, 2015


This next Friday, 27 of July, we could enjoy the longest lunar eclipse of the XXI century, this is a total lunar eclipse, and it will be visible for South America, Europe, Africa, Asia, Australia. The eclipse will have a duration of de 01h 43m or 103 minutes. This is a total lunar eclipse, where the moon becomes red, and might look quite dark, it is the first one for two years, and in six months’ time we will be able to enjoy another one, on January 21 of 2019.

Anatomy of the Eclipse 

The red colour that we see in the eclipse happens because the Earth blocks all direct sunlight from the umbra, the planet's atmosphere filters, attenuates and bends some of the Sun's rays into the shadow. The molecules in Earth's atmosphere scatter short wavelength light such yellow, green or blue, more than long wavelength light such the orange and red. This process, which is responsible for making sunsets red, also gives total eclipses their characteristic red-orange color. However, the exact color can vary considerably in both hue and brightness.
