The longest lunar eclipse of the 21st century

Next Friday, July 27, we will be able to witness the longest lunar eclipse of this century, which will last more than 102 minutes. The Moon, without disappearing, will turn a reddish hue.

Unlike solar eclipses, lunar can be seen from anywhere in the world, from the moment the Moon appears above the horizon. On this occasion, it can be fully appreciated in the Indian Ocean as communicated by the Instituto de Astrofísica de Canarias with information from NASA

The entire astronomical event will last up to 3 hours and 55 minutes: The shadow of our planet will completely block the rays of the Sun that the Moon reflects every night, making it look colors that will go from brown to red. Because of this tonality it is called "Blood Moon" and it will be the longest lasting event of this type between 2001 and 2100.

The longest lunar eclipses of the last century were two: one on July 16, 2000 that lasted approximately 107 minutes and another in July 1982.

How does a lunar eclipse occur?

The Moon must pass through the shadow of the Earth. Among the astronomical community, this phenomenon is known as umbra.

For there to be a lunar eclipse, bothour planet like the Moon and the Sun have to align, so that the natural satellite of the Earth darkens, but before our eyes it leaves its usual light color to adopt a red one.

This is due to the solar reflection, which is similar to when we see sunsets or sunrises of pink, orange, ocher or brown tones.

A video on YouTube produced by NASA helps to better understand how the Earth, the Moon and the Sun behave during the phenomenon known as the lunar eclipse.

Where you can look better

The astronomical spectacle can be seen in Africa, the Middle East, India, Australia and some areas of Europe, from where you will have a privileged and unique view of the longest lunar eclipse of this century.

The phenomenon, however, cannot be appreciated in North America or South America, reported IFL Science, a portal specialized in scientific topics.
