The last full moon of the year, often referred to as the Cold Moon in the Northern Hemisphere, officially marked the beginning of the astronomical winter, almost coinciding with last winter's winter solstice. Now astronomers will be on another treatment only a few weeks after the start of the New Year. The super moon of blood of 2019 will take place the night of January 20.
Interestingly, the super blue blood moon of 2018 occurred on January 31, marking one of the rarest celestial events related to the full moon. The moon looked quite large in the sky, hence the "super" part of the description. It also entered a total lunar eclipse and was the second full moon in the same month, which makes it a "blue" moon. The most recent total lunar eclipse occurred in July.
What happens during a lunar eclipse?
During a lunar eclipse, the moon's glow disappears slowly as it enters the earth's shadow. In a partial lunar eclipse, only a portion of the moon is covered by the Earth's shadow, while a complete lunar eclipse means that the surface of the entire moon falls into the shade. As its shape changes, the moon takes on a rusty texture, while the light creates a color similar to a sunset.
NASA scientist Noah Petro told Space.com in an interview that a lunar eclipse displays the colors of all sunrises and sunsets on Earth when light hits the moon. If one were to stay on the Moon during a total lunar eclipse, the Earth would seem to have a red ring around it.
When the lunar eclipse begins, the full moon begins to darken when it enters the outer shadow of the Earth, which is known as the penumbra. The deepest part of the Earth's shadow is called the umbra, and once the moon enters completely, it becomes a total lunar eclipse, exhibiting the recognizable reddish tint. The moon takes on the bright red color when it is totally in the shade, which is why lunar eclipses are often called the "moon of blood."
"A moon of blood is created [by] ashes of volcanoes and fires, dust storms and pollution, all filtering the sunlight as it spreads throughout the world. A gray eclipse is clear skies, "said astronomer and podcaster Pamela Gay at Space.com. "Our world can change the appearance of another world and during an eclipse the universe allows us to see this colorful game"
The 2019 super-moon will start in late January 20 in some time zones and will last one hour and two minutes, ending after midnight, NASA's Goddard Space Flight Center revealed in its lunar eclipse projections. However, all phases between the full moon and its total eclipse state last three hours and 17 minutes. It is expected to start on the East Coast at 12:16 PM Eastern on January 21.
The next total lunar eclipse after the Super Blood Moon of 2019 will not be until May 26, 2021, and is expected to be visible above the Pacific Ocean. People in North America, South America and East Asia will be able to watch the peak.
