August is bringing the first of four supermoons, delighting stargazers as the full moon draws closer to Earth than usual. This cosmic event offers enchanting views of our planet's constant companion, kicking off months of lunar spectacles.
The supermoon phenomenon occurs when the full moon aligns with its closest approach to Earth, making it appear both larger and brighter. Noah Petro, project scientist for NASA's Lunar Reconnaissance Orbiter, notes, “I like to think of the supermoon as a good excuse to start looking at the moon more regularly.”
While it's known as the 'supermoon,' the differences can be subtle. The anticipated moon on August 19 will be roughly 224,917 miles from our planet, only 3,000 miles farther than its next closest occurrence.
During supermoons, the moon can shine up to 30% brighter than when it is at its usual distance. This brightness can be more noticeable than the size difference, according to Petro.
For those hoping to witness the event firsthand, the moon will rise around 8:19 p.m. local time. While this supermoon brings excitement, it's not particularly rare; these events often occur three to four times each year.
What's interesting to note is the dual nature of this specific supermoon. Although many are captivated by its size or brightness, the term 'supermoon' doesn't have universally agreed-upon standards, lending to some confusion about its definition.
Supermoons can also coincide with eclipses, adding to their allure. September’s supermoon aligns with a partial lunar eclipse, promising even more spectacle for skywatchers.
Even when the moon doesn’t appear extraordinarily different, enthusiasts are reminded of its beautiful nature. “It certainly makes it more fun to stare at,” Petro adds, highlighting the surge of renewed interest with upcoming lunar missions.
Looking beyond supermoons, August also holds potential moon-related phenomena. The long-anticipated full moon is the first of the month and not to be confused with past or future blue moons, which have specific calendar definitions.
Interestingly enough, the excitement for this supermoon stretches beyond just amateur astronomers. Recent lunar exploration projects, including NASA's Artemis missions, are reigniting fascination with the moon as we gear up for more missions.
While the term 'blue moon' typically refers to the second full moon of the month, this August's event doesn’t fit this description. Many define it as this month’s singular full moon, as only 19 days have passed.
What's more exciting is the previous scientific discoveries made about our moon and its surrounding environment. Notably, scientists recently received samples from the moon's far side, brought back by the Chang'e 4 mission, providing valuable new insights.
Meanwhile, Mars is stepping up as another hot topic with new findings about its geological past coming to light. Data gathered from NASA's Insight lander indicates the presence of liquid water trapped deep under the Martian surface.
Even newer technological advancements are allowing scientists to peer even farther afield. NASA's James Webb Space Telescope has recently revealed large quantities of carbon-based molecules surrounding distant stars, painting broader pictures of atmospheres existing light-years away.
Even without distinguishing features, the moon remains breathtaking. Though the supermoon of August might not be groundbreaking scientifically, it's sure to inspire awe and spark curiosity among both casual and dedicated observers.
People around the world anticipate this extravaganza to witness one of nature's beautiful displays. Whether it’s beach bonfires, sky-gazing parties, or solo contemplation, there’s always something mesmerizing about the moon hanging high above.
So as August rolls on, take the chance to look up and perhaps appreciate the cosmos as twin events blend. It promises to be both visually delightful and reflective for those who ponder beyond the moon's surface.
