This November, the skies of various parts of the planet will witness the longest lunar eclipse of the 21st century since, according to astronomical data from NASA, it will last 3 hours, 28 minutes and 23 seconds, longer than any other phenomenon. of its kind between 2001 and 2100.
In fact, it will be the longest lunar eclipse in more than a millennium, since the last one that lasted that long occurred in 1440 and there will not be another similar one until 2669.
On this occasion, the shadow of the Earth will cover up to 97% of the full moon. Therefore, it will almost entirely acquire a reddish color from the scattered light of our atmosphere, which will result in a ‘blood Moon‘.
While it will technically be a partial eclipse, the magnitude of the shadow will make it look like a total eclipse, like the one seen in May of this year.
The lunar eclipse will take place on November 19 between 7.18 and 10.47 UTC, reported Timeanddate.com, a portal specialized in time zones and dates of astronomical events.
The maximum phase of the eclipse will occur in the middle of this period, when the reddish color will be appreciated almost in the entirety of the satellite: a blood moon.
On North America (Canada, the United States and Mexico), people will be able to witness the phenomenon for as long as possible: from when the Moon enters the Earth’s shadow until it leaves it
In Central America, the Caribbean and the western part of South America (Peru, Ecuador, Colombia and Venezuela), you can see the peak of the eclipse in a high sector of the sky, which is ideal. However, during the last moments of the eclipse, the Moon will have already moved below the western horizon.
In Chile, Bolivia, Paraguay, Uruguay, Argentina and western Brazil, the almost complete ‘blood moon’ will also be visible, but for less time and closer to the horizon.
In eastern Brazil, people can only hope to see a smaller shadow cast on the Moon, as it will dawn there before it becomes a ‘blood moon’.
Meanwhile, other parts of the Pacific will also witness the event, such as New Zealand, Japan, northeast China and eastern Russia. In these places, the clock will mark the first hours of the night of November 19.
A lunar eclipse occurs when the Earth is opposed between the Sun and the Moon. Consequently, the shadow or umbra of our planet is projected on the satellite.
However, instead of completely darkening, the Moon takes on a color that can be gold, coppery, or blood red. This happens because a part of the sun’s rays pass through the earth’s atmosphere and reach the lunar surface.
In this process, white sunlight — which travels in various wavelengths, some of which are visible colors — is scattered. Thus, the atmosphere filters most of the blue light, which is the shortest wavelength, and lets through the orange and red light, the longest.
