Week of April 27-May 3, 2025If you've been following my column for a while, you know that there are many kinds of constellations in the sky. You also know that most of these look nothing like their namesakes but are simply celestial representations of objects, animals and people. We in the Western Hemisphere know of 88 constellations distributed around the heavens, passed down to us by ancient skywatchers.

When I was in grade school I was fascinated by the world’s largest telescope: the 200-inch-diameter Hale Reflector on Palomar Mountain near San Diego. What a behemoth!At the time I enjoyed using a 4.25-inch telescope in my backyard, and it’s stunning to realize that I would have needed more than 2,200 similar telescopes all working in synch to match the light-gathering power of the giant telescope at Palomar Observatory.

Spring has sprung in the Earth’s Northern Hemisphere, and with it come some pleasant evenings perfect for stargazing. And front and center right now appears one of the most familiar and easy-to-find star groupings: the Big Dipper. We in North America call it the Big Dipper, but those in Great Britain know it as the Plough. Stargazers in Germany and Scandinavian countries recognize it as a wagon.

Make plans now to step outside just before sunset on Saturday, April 12. If you do, and if the sky is clear, you’ll be able to watch the beautiful full moon rising over the eastern horizon. Now you may say that it looks close enough to touch, but much of what you’ll see that night isn’t real. It’s an optical trick known as the “moon illusion” that our brains play on us to make the moon appear larger than it really is.
