Cows graze as the near-full Harvest Moon rises over a hilltop pasture in Massena, Iowa, on Thursday, Sept. 28, 2023. It was the fourth and final supermoon of 2023, capping off a summer full of big, bright full moons. A supermoon happens when the moon is at or near its closest point to Earth in its orbit. During those times, the moon can appear larger and to shine brighter than at other points in its cycle. 📸: @bryon_houlgrave @dmregister
