Have you ever watched a lunar eclipse? It’s an amazing event where the moon takes on a mysterious, reddish glow. Some people might think it’s a sign of something big, but really, it’s just a cool astronomical event!
The moon is our constant companion in space, orbiting around Earth as we orbit the sun. It’s made of dust and minerals and has lots of craters. Sometimes, the moon passes through Earth’s shadow, creating a lunar eclipse. This happens only during a full moon when the Earth is directly between the sun and the moon.
Next Monday, we’ll see the first of four lunar eclipses happening over the next two years. When four full lunar eclipses occur in a row without any partial eclipses in between, it’s called a tetrad. These are pretty special! In the 20th century, there were 81 lunar eclipses, including five tetrads. In the 21st century, we expect 85 eclipses and eight tetrads, the most since the 9th century!
During a full lunar eclipse, the moon doesn’t disappear completely. Instead, it turns a rusty red color. This happens because Earth’s atmosphere scatters sunlight. Red light, which travels in longer waves, passes through the atmosphere and lights up the moon. This is similar to why the sky looks orange or red during a sunset.
People have been naming moons for a long time. Before electric lights, everyone could see the stars, planets, and moon clearly, leading to stories and names for these celestial bodies. A “Blue Moon” is when there are two full moons in one month. The “Harvest Moon” is the full moon closest to the autumn equinox, and the “Hunter’s Moon” follows the Harvest Moon.
Some people call a total lunar eclipse a “Blood Moon” because of its red color. While it might sound spooky, it’s just a beautiful sight for astronomers. A total lunar eclipse happens when the sun, Earth, and moon align perfectly, a setup known as a syzygy.
During the upcoming eclipse on April 15th, you can also see Mars near the moon. If you’re in North or South America, you’ll have a great view without needing a telescope, but using one can make it even more exciting!
The eclipse will start around midnight Pacific time. Have you ever seen an eclipse? Are you planning to watch this one? It’s a great opportunity to witness a fascinating natural event!
If you enjoy learning about interesting topics, you might be curious about how birth control methods have changed over time. Before modern methods, people used some surprising techniques. If you want to discover more about this, check out a new show called Anyhoo. It’s packed with fascinating information!
Gather materials like a flashlight, a small ball (to represent the moon), and a larger ball (to represent Earth). Use these to create a model demonstrating how a lunar eclipse occurs. Shine the flashlight on the “Earth” and move the “moon” into Earth’s shadow. Notice how the moon changes color. This hands-on activity will help you understand the alignment of the sun, Earth, and moon during an eclipse.
Work in groups to research the concept of tetrads. Find out when the next tetrad will occur and why they are significant. Create a short presentation or poster to share your findings with the class. This will help you learn more about the frequency and importance of these rare events.
Use art supplies to create your own depiction of a “Blood Moon.” Consider using red and orange hues to capture the moon’s appearance during a total lunar eclipse. Display your artwork in the classroom and discuss why the moon appears red during an eclipse. This creative activity will reinforce your understanding of atmospheric scattering.
Research the traditional names of full moons, such as the “Harvest Moon” or “Hunter’s Moon.” Write a short story or poem inspired by one of these names. Share your work with the class to explore the cultural significance of moon names. This activity will deepen your appreciation for the historical and cultural aspects of lunar observations.
Organize a viewing party for the upcoming lunar eclipse. Plan activities like stargazing, using a telescope, and identifying Mars in the night sky. Create a checklist of what to bring and what to look for during the eclipse. This will enhance your observational skills and make the experience more memorable.

Everyone loves a good lunar eclipse! Especially those who think the moon is some kind of signal indicating the end of days.
Happy Friday! Trace here with your DNews Weekly Space update. The moon is our celestial partner, orbiting around us as we travel around our star. It’s a fascinating object, made of dust and minerals with craters on its surface. While it’s beautiful, it’s not a sign of doom.
Next Monday, we will experience the first of four lunar eclipses over the next two years. When they occur in succession like this, astronomers refer to them as a tetrad, which means a set of four. Tetrads consist of four consecutive full eclipses with no partial eclipses in between.
Lunar eclipses are more common than you might think. According to Universe Today, there were 81 lunar eclipses in the 20th century alone, including 5 tetrads! The 21st century is expected to have 85 eclipses and 8 tetrads, the most since the 9th century!
Many of these will be partial eclipses, but a full lunar eclipse occurs when the moon passes through the Earth’s shadow. This always happens during a full moon, as that’s the only time the Earth is positioned between the sun and the moon. The Earth’s shadow doesn’t completely block the moon; instead, it takes on a rusty color.
As the moon moves into the Earth’s shadow, our atmosphere scatters sunlight. Red light, which has a longer wavelength, is scattered the least and makes it through our atmosphere to illuminate the moon. This is why the moon can appear orange when it’s low in the sky, similar to the colors seen during sunsets.
Naming the moons is a tradition that dates back to ancient history. Without electric lights, the movements of the stars, planets, and the moon were observable by everyone, leading to stories that explained their movements. A Blue Moon refers to two full moons in the same calendar month, while Harvest Moons occur nearest the autumnal equinox. The Hunter’s Moon is the full moon that follows the Harvest Moon.
The internet has turned the term “Blood Moon” into something apocalyptic, but in reality, it’s just a beautiful sight for astronomers. Total lunar eclipses occur when the Sun, Earth, and Moon are in alignment, a phenomenon known as a syzygy.
Additionally, Mars will be visible to the right of the moon during this eclipse on April 15th, which will be the first of the upcoming tetrad. If you’re in Asia or Europe, you might miss it, but those in North or South America will be able to see it without a telescope. However, if you have one, it will enhance the experience!
The eclipse will start around midnight Pacific time. Have you ever seen an eclipse? Are you planning to watch this one? Share your thoughts in the comments below, and subscribe for more DNews.
Speaking of interesting topics, birth control methods have evolved significantly over time. Before the pill, many people were unsure about effective contraception methods. Some even resorted to unconventional methods. If you want to learn about some surprising ancient birth control techniques, check out this new show I’m involved with called Anyhoo. It’s fantastic!
