The universe isn’t just something to read about or see in photographs. It’s something you can explore.

From watching our ever-changing Sun through specialized solar telescopes to discovering the Moon, planets, and distant objects in the night sky, public observing events offer opportunities to experience astronomy up close.

You don’t need your own telescope or any previous experience. Just bring your curiosity, ask questions, and see what you discover.

Your world is bigger than today.


Ready to look up? The Colorado Springs Astronomical Society (CSASTRO) hosts public astronomy events throughout the year, offering opportunities to explore the Sun, Moon, planets, and more.

Public events are open to curious visitors of all experience levels. Observing opportunities depend on weather, sky conditions, and the equipment available at each event.

Check the calendar for upcoming events, locations, and details before heading out.


Our closest star is constantly changing. At daytime observing events, you may have the opportunity to safely view sunspots, solar prominences, and other features through specially equipped solar telescopes.

As darkness falls, the universe reveals a different set of wonders. Depending on the season and observing conditions, you might explore the Moon’s craters, planets, star clusters, nebulae, or distant galaxies.
