Week of May 18-24, 2025Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it's the brightest star in the heavens, and they are disappointed when they see it. It's faint. Really faint. If you listed the brightest stars in the sky, you'd discover that Polaris isn't even in the top 10. It's not in the top 20, the top 30 or the top 40.

Gaze skyward on any spring and summer night and you’ll surely see what appears to be a star drifting slowly across the night sky. This is probably an Earth-orbiting satellite. I should remind you that if it’s got red and green blinking lights, don’t get too excited. That’s an airplane!Keep watch for an hour or so and you’re sure to see quite a few satellites. I recall watching for satellites outside with my dad back in the early 1960s.

Week of May 4-10, 2025OK, I admit I may not remember where my car is parked, but I sure recall my grade school planetarium field trips like they just occurred. These were some of the highlights of my youth, and they played a huge role in my decadeslong career as a planetarium astronomer. It was great fun seeing the stars and constellations projected onto the overhead dome while the lecturer pointed them out and told stories about those visible that night.
