When you step outside on a crisp winter evening in Boulder, you’re greeted by a sky teeming with ancient myths and stories. One of the most compelling scenes unfolds in the southeast, where Orion chases the Seven Sisters (Pleiades), with Sirius shining brightly nearby. It’s a celestial love triangle — or rather, a star-studded drama — that has fascinated skywatchers for centuries.

A Tale of Pursuit: Orion and the Seven Sisters

Orion, the mighty hunter, is among the most recognizable constellations in the winter sky. Its three-star “belt” points toward a faint cluster of stars called the Pleiades, or “Seven Sisters.” According to Greek mythology, Orion developed an ardent pursuit of these sisters, who wanted nothing to do with him and begged the god Zeus for protection.

Zeus responded by placing Taurus the Bull (with its red eye Aldebaran) between Orion and the fleeing Pleiades. Each night, you can watch them race across the sky: Orion in hot pursuit, Taurus bravely defending the sisters, while Sirius and the rest of Orion’s faithful dogs give chase from behind.

Orion: The Global Icon

Orion’s bright stars — Betelgeuse (the red shoulder) and Rigel (the blue-white foot) — make it a global icon. In fact, this constellation is visible from both hemispheres, though Australians know it in an upside-down orientation sometimes called the “Saucepan” or the “Shopping Trolley.”

• The Orion Nebula: Just below Orion’s belt, the “sword” conceals a cosmic nursery known as the Orion Nebula. Through binoculars or a small telescope, you can glimpse a cloudiness revealing baby stars in the making.

Sirius: The Brightest Star at Night

Down and left from Orion’s belt (in the southern sky) is Canis Major, home to Sirius, the brightest star visible at night. Known as the “Dog Star,” Sirius has been recognized for millennia:

• Ancient Egyptians linked its rise to the flooding of the Nile, calling it a harbinger of change and renewal.
• The term “dog days” stems from the period in which Sirius aligned with the sun, causing scorching heat in midsummer (in older times and different latitudes).

Pro Tip: If you’re scanning Boulder’s sky in late winter, Sirius is that brilliant, unmistakable jewel near the horizon, shimmering through atmospheric turbulence.

The Seven Sisters (Pleiades): A Teenage Star Cluster

High above Orion is the delicate cluster of Pleiades, often mistaken for a “mini dipper.” Most people can see six bright stars here, but under dark skies (and with excellent vision), you might catch the elusive seventh. With binoculars, you’ll notice dozens more.

In star terms, the Pleiades is an “open cluster” of relatively young stars — cosmic teenagers leaving their stellar nursery in the Orion Nebula to roam the Milky Way.

Myth Meets Science

This interplay of mythology and astronomy illustrates how a single patch of sky can hold countless stories:

• Orion’s Belt leads us to star-forming nebulae.
• Sirius ties us to ancient Egyptian culture and the “dog days” of summer.
• Taurus signals the bull’s protective stance, and
• The Pleiades remind us of cosmic youth and wide-eyed wonder.

It’s proof that what we see overhead isn’t just a bunch of random lights but a living tapestry of folklore, culture, and scientific inquiry.
