Why the Moon Appears Larger Near the Horizon
Is the Moon Really Bigger Near the Horizon? The short answer is no. The Moon’s physical size does not change during the night. In fact, when the Moon is near the horizon, it is actually slightly farther away from you than when it is overhead. That’s because when it’s overhead, you are about one Earth radius (roughly 6,371 kilometers) closer to it than when it’s on the horizon.

What Causes Meteor Showers at Specific Times of Year?
What Is a Meteor Shower? A meteor shower occurs when Earth passes through a stream of debris left behind by a comet or, in some cases, an asteroid. As tiny particles of rock and dust enter Earth’s atmosphere at high speed, they burn up due to friction with air molecules. This creates bright streaks of light known as meteors.

The Forgotten Half: Why We Teach Everything Except How to Be Human. AI-Generated.
There is a curriculum we teach, and there is a curriculum we ignore. The first is written in standards and textbooks, measured by tests and grades, celebrated in awards and acceptances. It includes mathematics and literature, science and history, the accumulated knowledge of centuries passed from one generation to the next. This curriculum is important. It opens doors, builds skills, creates the foundation for careers and contributions. We have become very good at teaching it.
