How to see the Milky Way's core — and why it's harder than it used to be

Every thirteen months, Earth laps Jupiter in their orbits around the Sun, bringing the giant planet to opposition — closest approach, fully illuminated, visible all night.

Saturn's rings appear to open and close as the planet orbits the Sun, presenting a full face every fifteen years or so — and then nearly vanishing as they tilt edge-on. We are approaching one of those disappearing acts. Understanding the geometry, and how to watch it unfold, makes an ordinary telescope into a front-row seat for orbital mechanics.
