Dark Skies & Stargazing

Clubs, observatories & star parties

You don't have to figure this out alone, and you don't have to buy anything first. Missouri's astronomy clubs run free public nights where you can look through real telescopes — the friendliest, fastest way in.

The fastest, friendliest way into stargazing is a free public star party or an observatory: show up, look through big telescopes, and ask all the questions you want — before you spend a dime on gear. The people who run these nights love nothing more than handing a beginner their first look at Saturn's rings. Find a club near you below.

St. Louis Astronomical Society (SLAS)

Founded in 1936; free public meetings (third Friday at Washington University) and star parties, including at Babler State Park and the Jefferson College Observatory.

Astronomical Society of Eastern Missouri (ASEM)

Free Friday-night open houses at the Broemmelsiek Park Astronomy Site (St. Charles County — 10 telescope pads with power), plus beginner nights and an astrophotography group.

Astronomical Society of Kansas City (ASKC)

Runs Powell Observatory, which is in Louisburg, Kansas — a KC-metro resource, not in Missouri — with seasonal public nights (donations may be requested), plus KC-area star parties.

Central Missouri Astronomical Association (CMAA)

Wednesday open houses at the University of Missouri's Laws Observatory in Columbia, and mid-Missouri star parties.

Public observatories

Laws Observatory (Columbia) and the historic Morrison Observatory (Central Methodist University, Fayette — built 1875, with free public sessions on select evenings).

Planetariums

The James S. McDonnell Planetarium (St. Louis Science Center) and Science City's Arvin Gottlieb Planetarium (Union Station, Kansas City) — great for a cloudy night or a first taste.

Library telescope loans

Some Missouri library systems lend telescopes free with a library card (for example, St. Louis County Library, about a 21-day loan).

Most of these are free or low-cost, but schedules and donations vary, and weather cancels — always check the calendar before you drive.

The festival

The Missouri DarkSky Festival at Big Spring (Ozark National Scenic Riverways), held with the NPS. DarkSky Missouri lists a 2026 festival on October 9–10, but the dates change every year — check before you plan.
