Picture this: the night sky transformed into a breathtaking canvas of luminous wonder, courtesy of the final supermoon of 2025. This celestial event isn't just another pretty sight—it's a reminder of how our world and the heavens above can collide in spectacular ways. But here's where it gets intriguing: is this 'supermoon' truly super, or is it all an optical illusion fueled by our perceptions? Let's dive into the details and uncover what made this lunar display so captivating, and maybe along the way, we'll challenge a few assumptions about astronomy.
From Thursday evening through the early hours of Friday, the last supermoon of 2025 captivated stargazers worldwide, casting an enchanting glow across the heavens and illuminating landscapes in ways that felt almost otherworldly. As reported by the Beijing Planetarium, this magnificent moon reached its peak fullness at precisely 07:14 Beijing time on Friday morning. If you missed it, don't fret—there's more to explore in our related piece on the supermoon lunar eclipse, where we break down exactly what viewers witnessed (link: https://www.pbs.org/newshour/science/catch-the-supermoon-lunar-eclipse-heres-what-you-saw).
About 12 hours earlier, our lunar companion hit its perigee, the point where it's closest to Earth, with the Earth-moon distance shrinking to under 360,000 kilometers. This configuration fits the classic criteria for a supermoon, making it the second most sizable full moon of the year. Dubbed the Cold Moon—aptly named for the chilly December nights it adorned—the event stood out even more against the backdrop of recent lunar spectacles.
Just a few weeks prior, in November, we were treated to an even more impressive supermoon that peaked nine hours before perigee, while October brought a subtler one. This progression highlights how supermoons can vary in intensity, depending on precise orbital timings. For beginners in astronomy, think of perigee as the moon's 'close-up' moment in its elliptical dance around Earth—it's when we get the best view, even if the difference in size is subtle and not always noticeable to the naked eye.
Astronomers reveal that the key to savoring a supermoon at its absolute best boils down to perfect timing and vantage points. They emphasize catching the 'golden hour' right after sunset, when the moon first ascends on the horizon. Against the silhouettes of trees, buildings, or even ships on the water, it can look dramatically enlarged and plump, creating an illusion that's nothing short of mesmerizing.
Take, for instance, the way it lit up the sky over Warsaw, Poland, or Porto Alegre, Brazil, or even as it framed a vessel gliding through the Strait of Magellan in Punta Arenas, Chile. Rising majestically over Panama City, Panama, the Cold Moon turned ordinary nightscapes into postcard-worthy scenes. But here's the part most people miss—and it's where the controversy kicks in: that perceived bigness isn't always real.
As Kou Wen, a senior engineer at the Beijing Planetarium, explains, 'When the moon just rises, it may appear larger against terrestrial scenery. By midnight on the same day, when it’s high in the sky with no contrasting objects around, it seems smaller. This isn’t an actual change in size, but an illusion.' This phenomenon, known as the Moon Illusion, has sparked debates among astronomy enthusiasts and skeptics alike. Some argue it's just a psychological trick, a way our brains compare the moon to nearby objects, much like how a coin held at arm's length looks huge against a distant mountain. Others claim supermoons are overhyped, a modern label that turns natural events into buzzworthy spectacles. What do you think—is this illusion a harmless fun fact, or does it undermine the 'wow' factor of real astronomical wonders? Share your take in the comments below!
Looking ahead, the next supermoon won't grace our skies until December of next year, but Kou hints it could be even more remarkable. 'The next such supermoon will occur in December of next year. That time, the interval between passing perigee and the full moon will be only about six or seven hours, making it even closer than both occurrences this year,' he notes. This promises an even tighter alignment, potentially offering sharper contrasts and brighter illumination for future observers.
