Here's how to see the 'blood moon' tomorrow

The lunar eclipse happening this weekend will be a special event! With a duration of 1 hour and 43 minutes, it's the longest one of the 21st century.

According to Vogue, the blood moon will be fully visible from Africa, Central Asia, and the Middle East, but only partially visible from North and South America.

The eclipse will not be visible in Greenland and Canada either. Read more on Twitter, @amomama_usa.

Slooh, an astronomy education website, will be live-streaming the eclipse for those who won't be able to view it. Netizens can tune in from 1 pm EST on July 27.

The moon will have an orange or 'reddish-brown' hue, also known as a blood moon, and will pass through the earth's shadow when the sun and moon line up with the planet.

Because the light from the moon is passing through the earth's atmosphere, the longer red light wavelengths are reflected on the moon's surface.

The next eclipse will be in January 2019.

This process is called refraction because the red light waves from the sun bend around the earth, almost like a camera lens bends light.

If the earth had no atmosphere, the moon would be black because the color of the moon during an eclipse depends on the atmospheric conditions on that specific date.

A lunar eclipse is safe to look at with the naked eye. However, viewers should never look directly at a solar eclipse as looking directly at the sun can be dangerous.

According to the Guardian, no special filters or protective glasses are needed, and most people will be observing from the comfort of their gardens.

There will be more than 200 lunar eclipses during this century, but only 85 of them will be total lunar eclipses.
