May’s night sky is putting on a show, and personally, I think it’s one of the most underrated celestial events of the year. Sure, everyone gets excited about meteor showers or eclipses, but this month’s lineup feels like a quiet masterpiece for those who bother to look up. Let’s start with the so-called ‘blue moon’ on May 31st. What many people don’t realize is that the term has almost nothing to do with the moon’s color—unless you’re talking about the rare instances when volcanic ash or wildfires turn it blue, like after Krakatoa’s eruption in 1883. But those are exceptions, not the rule. The phrase ‘once in a blue moon’ is more about rarity than hue, and its origins are surprisingly mundane. It’s not tied to ancient folklore or astronomy but rather to a 19th-century British journalist, Pierce Egan, who likely picked it up from London slang. If you take a step back and think about it, it’s fascinating how a phrase born out of linguistic whimsy became a global astronomical ‘tradition.’
What makes this particularly fascinating is how the term evolved. In the 1930s, an editor of the Maine Farmers’ Almanac decided to label the third full moon in a season with four as a ‘blue moon.’ Then, in 1946, an astronomer misread that definition and declared that any second full moon in a single month was a blue moon. This version stuck, thanks in part to Trivial Pursuit, and now it’s what most people think of. But here’s the kicker: the ‘traditional’ definition is barely a century old, and the popular one is even younger. It’s a reminder that even our most cherished traditions can have surprisingly recent origins.
Now, let’s talk about Venus. This month, it’s the undisputed star of the evening sky, blazing as the Evening Star. What this really suggests is that even in our light-polluted world, there’s still magic to be found if you know where to look. If you’re far from city lights, you might even see shadows cast by Venus’s glow—a rare sight that feels almost otherworldly. And then there’s Jupiter, hanging out near Castor and Pollux, adding to the spectacle. From my perspective, what’s most captivating is how these planets and the Moon will play tag in the western sky around mid-month. On May 18th, the crescent Moon cozies up to Venus; the next night, it’s sandwiched between Venus and Jupiter. It’s like a celestial ballet, and it’s free to watch.
One thing that immediately stands out is how these events connect us to something larger. The constellations we see this month—Leo, Virgo, Hydra—are the same ones our ancestors observed thousands of years ago. Hydra, for instance, is not just the largest constellation but also one of the oldest, dating back to a time when its shape marked the celestial equator. It’s a humbling reminder of how small we are in the grand scheme of things. Yet, at the same time, it’s empowering to think that we can still find meaning and wonder in these ancient patterns.
If you’re new to stargazing, May is a perfect month to start. The Plough (or Big Dipper) is easy to spot and acts as a guidepost to other stars like Arcturus and Spica. What many people don’t realize is that these constellations aren’t just random dots—they’re stories, myths, and navigational tools passed down through millennia. Personally, I think that’s what makes stargazing so special. It’s not just about seeing stars; it’s about connecting with history, science, and our place in the universe.
This raises a deeper question: Why do we find these events so captivating? Is it the rarity, the beauty, or the sense of connection to something greater? In my opinion, it’s all of the above. May’s night sky isn’t just a collection of celestial events—it’s an invitation to pause, reflect, and marvel at the world beyond our own. So, whether you’re watching for the blue moon, Venus’s glow, or the ancient constellations, take a moment to appreciate the show. After all, it’s not every month that the universe puts on such a performance.
