In the early hours of Tuesday, darkness slips across the face of the moon before it turns a deep blood red. No, it is not the choice of the day of the omen – it is the one seen by all eyes in the night sky.
Anyone watching in the United States will have a front seat as the Sun, Earth and Moon line up as the Moon passes through the Earth’s shadow during the last lunar eclipse until 2025.
“To me, the most remarkable thing about a lunar eclipse is that it gives you a sense of three-dimensional geometry that you rarely get in space – one sphere passing through the shadow of another,” said Bruce Betts, chief scientist at the Planetary Society.
Here’s what you need to know about viewing the eclipse.
When and where to observe eclipses
In North America, observers on the west coast will get the best view. At 12:02 am Pacific time, the moon will enter the outer part of the Earth’s shadow and darken ever so slightly. But the total eclipse time – the star of the real show doesn’t start until 2:16 a.m. That time is called totality, when the moon enters the innermost part of the Earth’s shadow and shines a deep blood color. Totality will last for about 90 minutes until 3:41 am, and by 5:56 am the moon will be a familiar silver color.
“This will be a big issue before election day,” said Andrew Fraknoi, an astrologer at the University of San Francisco. “I joke around that a lot of people are so nervous about Election Day this year that they’ll probably stay up all night and watch it.”
Viewers on the East Coast, on the other hand, will have to move alarms first. Although they won’t be able to see the entire eclipse, they can catch totality, which will occur from 5:16 am Eastern Time to 6:41 pm, roughly when the moon will be touching the northernmost part of the United States. Early risers should look toward the horizon between the northern hemisphere to catch the red moon.
For those in the Midwest, the total red moon will be visible from 4:16 a.m. Central time until 5:41 a.m. And for those in the Rocky Mountains, it will be total one hour earlier.
Forecasters have predicted rainy conditions across the West Coast overnight, which could affect the appearance of the eclipse. Some cloudy skies or fog could appear in central parts of the United States, from Minneapolis to cities in Texas. Weather reports suggested mostly clear conditions overnight along the eastern seaboard.
Across North and Central America, sky watchers will be able to observe the eclipses in Asia and Australia, where they occur in the early evenings after the moon rises. NASA’s visible map provides more details.
No matter where you are and what part of the eclipse occurs, it is safe to watch with your eyes open.
What does the blood moon do?
It may be surprising that the moon simply does not darken when it enters the shadow of the Earth. This is usually the light of the moon and the sun. And while the lunar eclipse is mostly blocked by that sun, some of it wraps around the edges of our planet, edges that experience sunrise and sunset at the same time. Those filters filter out the shorter, bluer wavelengths and allow only the redder, longer wavelengths to hit the moon.
“It’s a romantic trip to watch because it’s like seeing all the sunsets and sunrises on Earth at one time,” said Dr. Betts.
This mind is quite different from that of some of our ancestors. “For many cultures, the waning of the moon is seen as a time of danger, of chaos,” said Shanil Virani, an astrologer at George Washington University.
Incapable, for example, thought that a jaguar attacked the moon during an eclipse. They saw an attack on their king in Mesopotamia. In ancient Hindu mythology, a demon devoured the moon.
But not all lunar eclipses result in deep red which has led to the nickname “blood moon”. that, just as the intensity of the sun or the sun cannot vary from day to day, so also the colors of an eclipse. It depends mainly on the particles in our planet’s atmosphere. A fire or the dust of a mill can deepen the red colors of a sunset, and it can also affect the color of a lunar eclipse. But if the air during a lunar eclipse is particularly bright, more light will be lost, so that the moon will be lighter red, perhaps even reddish orange.
Failure to study using exoplanets
The Moon’s color signatures from our atmosphere – therefore our – art, can be used for future observations of planets around distant stars.
Astronomers typically do not observe exoplanets directly. Instead, they wait for transits, or telltale blips, when a planet passes in front of its parent star. At such a time the light of the stars is filtered through the atmosphere of the exoplanet in the same way that, during a lunar eclipse, the light of the sun passes through the atmosphere of the Earth before it strikes the moon.
In this way, astronomers can treat a lunar eclipse as a proxy for the transit of an exoplanet. “The moon is basically used as a mirror to watch the Earth pass the sun,” said Allison Young Blood, an astronomer at NASA’s Goddard Space Flight Center in Greenbelt, Md.
In January 2019, Dr. Young Blood and his colleagues trained the Hubble Space Telescope on the moon during a total lunar eclipse. Because chemicals in the Earth’s atmosphere prevent certain wavelengths of sunlight from reaching the moon — thus leaving it submerged in the observed spectrum — the team of Dr. Young was able to detect blood ozone.
“It’s kind of like a round of practice,” Dr. Youngblood said. By treating Earth as an exoplanet, astronomers can double check that they are correctly detecting atmospheric details when observing other stars.
But Manisha Shrestha, an astrologer at the University of Arizona, has a different idea in mind. On Tuesday, the Bok Telescope at Arizona’s Kitt Peak National Observatory plans to observe a lunar eclipse with the hope of spotting not only certain chemicals in our atmosphere, but also their distribution.
This technique has never been done before on exoplanets and could mean that future detections reveal not simply whether an exoplanet has clouds, but whether those clouds cover the universe in density or are slightly uneven, like clouds on Earth. If those clouds were uneven and composed of water vapor, that exoplanet would only be Earth 2.0.
But you don’t need a scientific method to enjoy the eclipse. Astronomers agree that it’s the perfect opportunity to take a break from the politics of election season and just take stock of the world.
“From a cosmic perspective, our problems are temporary things – they pass the imaginations of the human species,” said Dr. Fraknoi. “Eclipse connects you with cycles and rhythms that are much older.”
