Archeoastronomy is the study of how ancient civilizations understood celestial phenomena. They integrated this understanding into cultural and religious frameworks. Some famous archeoastronomy sites are in the Egyptian pyramids and on Easter island. Mythological texts, ritual calendars, and religious ceremonies synchronized with planetary movements. Some examples are the Sun Temple in Mesa Verde, and the complexes at Chaco Canyon near Aztec, New Mexico.

Have you ever looked up and witnessed spectacular displays of green, white, pink and yellow lights? If you have ever visited the polar regions, or the auroral oval on Earth; then your response most likely should be a yes. The official names for these extraordinary lights are called aurora borealis, for the Northern hemisphere; and aurora australis, for the southern hemisphere.

The Sun is the star at the center of our Solar System. The Sun governs our daily lives, and energy from the Sun has been essential for nearly all life on Earth for more than 3 billion years. But what if there were two, three, four, five, or even six Suns in our sky? That question might seem ridiculous, but it turns out that more than half of the stars in our galaxy are either in double star or multiple star systems that are held together by gravity.

Nature operates on an intricate and precise schedule, guided by circadian rhythms—internal biological clocks that regulate sleep, activity, feeding, and reproduction. These rhythms are not only essential for human health but are also fundamental to the behavior of migratory birds, pollinators, and even the crops we cultivate. Understanding these natural cycles is crucial, particularly in rural communities where agriculture and wildlife conservation are deeply interconnected.

It was a beautiful summer evening in Western Colorado. The Sun had just set and our bright sister planet was just starting to pop out in the darkening sky. I quickly pointed the telescope at Venus, which was in a crescent phase, for an eagerly awaiting crowd. The first person squinted into the eyepiece and said, “I see the Moon, but I don’t see Venus.” I was taken back a bit, as the Moon was nowhere to be seen in the sky. Assuring the crowd that I was not deceiving them, I responded, “That IS Venus! Venus goes through phases, just like the Moon!”

We live in a world that rarely slows down—late-night work, glowing screens, and irregular schedules have become the norm. But what if I told you that constantly ignoring your body’s natural rhythms could put you at risk for serious diseases, including heart disease and breast cancer? The key to understanding this lies in our circadian rhythm—our body’s internal 24-hour clock that regulates sleep, metabolism, and cellular repair among other bodily processes.

Do you enjoy stepping outside at night and looking up to see a sky full of stars? For much of human history, that was the norm. But today, in many places, the night sky is drowned out by artificial light. While streetlights and glowing screens may seem harmless, they’re disrupting something vital—our circadian rhythms.

On the night of March 13 to 14, the Moon will move through Earth’s shadow, creating a total lunar eclipse that is visible from Colorado.

Planetary alignment is a phenomenon where other planets in our solar system align from Earth’s perspective. It is a rare event with some alignments occurring once in 100 years.

Fermi was a Nobel Prize winning physicist famous for quickly estimating answers to questions, like how many heart beats are there in a lifetime, or how many piano tuners are there in Chicago? These types of questions are now called Fermi questions. Perhaps the most famous Fermi question is the Drake equation, which asks how many advanced civilizations exist in our galaxy.
