The Moon will go through the shadow of the Earth tonight in the only total lunar eclipse of 2019, and you will not want to miss it! In this case you have to wait two years for the next one. And if you are in North America, you have to wait until 2022!
Skywatchers in North America will receive heavenly delicacies late on Sunday (January 20) and early Monday (January 21) as the moon goes into darkness and becomes blood red. While the weather will be very cold for many in North America, astronomers say they should now summarize and check the sights. This is because the next total solar eclipse will take place in 2021 and Americans will have to wait until 2022 for a blood moon to be visible from where they are located. Today's lunar eclipse takes place while the moon is near the nearest Earth's point on earth, which some refer to as the "Supermoon". Since the full moon in January is also known as Wolf Moon, this meant that the moon tonight is referred to as Super Blood Wolf Moon.

Lunar eclipses occur when the moon falls in the shadow of the earth. In a total eclipse, the moon goes so low into the shadows that all the light that reaches its surface comes only from the edge of the earth, where sunrises and sunsets take place. This light falls on the moon and turns red or sometimes appears redder, depending on how dusty your local atmosphere is (among other things).
Because of the geometry of the earth, the sun and the moon, sometimes there are periods in which no lunar eclipses occur for a long time. This situation occurs every 19 years, said David Dundee, an astronomer at the Tellus Science Museum in Cartersville, Georgia, opposite Space.com.
"There are actually more than a number of patterns that all run simultaneously," he wrote in an email. "[It all] has to do with how the moon's orbit oscillates north and south." When the orbit passes through the Earth orbit, this is a "knot," which is the case when a lunar eclipse can occur properly. " In other words, the moon does not experience a total solar eclipse for a while, because the moon's orbital nodes are not taking place at the right time for the full moon to cross the Earth's shadow.
The sun is also going through a quiet cycle for solar eclipses that occur when the moon passes in front of the sun. Solar eclipses, however, are much more complicated – not just because they need special protection for your eyes. While skywatchers in the US have had the chance of seeing a solar eclipse from coast to coast, the shadow of the moon is so small that a total lunar eclipse goes over a band that covers only 70 to 100 miles (112 to 161 kilometers) Said Dundee , Total lunar eclipses, on the other hand, are visible throughout the earth's hemisphere.
Whether you're watching the lunar eclipse this weekend via webcast or in person, Dundee has some tips to look for.
"Look for the edge of the shadow that covers the moon, it will be fuzzy or irregular," he said. "This is because of the Earth's atmosphere, [it] will cause the edge of the shadow to be poorly defined, and in the course of the solar eclipse you can see that the shape of the shadow is round, a consequence of life on a circular planet." Finally, the color of the fully occluded moon depends on the amount of dust in the Earth's atmosphere and the cloud cover in other parts of the earth. "
Lunar eclipse does not require any special equipment – just your own eyes and some warm clothing – if you have binoculars or a telescope handy, you may see a little more detail about the lunar functions, but you can usually get more red in the sky
