Chicago's Best Stargazing Spots

Chicago’s celestial landscape is bright and beautiful, but it’s virtually invisible because it’s obscured behind the orange glow that emerges from the city’s streetlights and buildings each night. This obscured sky has hundreds of thousands of stars, dotted with bright travelling planets, crisscrossed by satellites and burning meteors. To see that sky, you need a dark sky, and in Chicago — a city of stage-lit skyscrapers, sprawl and sodium streetlights — it just doesn’t get dark enough to see more than a handful of the brightest stars and planets.

According to Larry Ciupik, an astronomer at Adler Planetarium, Chicago is one of the most light-polluted cities in the world. One of the many potential consequences of that is clear, he says:

As the night sky fills up with more artificial light from increasing development and glare from unshielded streetlights, more people are forgetting what darkness even looks like. Or, worse, they never experience it at all.

“I think we gradually become used to not seeing the sky,” Ciupik says. “But it’s a whole kind of primal feeling when you see a very dark sky. A black sky with thousands of stars … you can’t duplicate [that] even inside of a planetarium. Artificial doesn’t compare to reality.”

That reality hit our questioner, Paula de los Angeles, between the eyes when she moved to Chicago a few years ago. Having grown up in a small town in Connecticut, she missed seeing the stars when she looked up at Chicago’s night sky. And she asked for help finding them:

What are the best spots in Chicago or the suburbs to stargaze?

To Paula, moving to Chicago not only meant she had to give up seeing stars, but also the feeling that goes along with it: She misses the part of herself that had been filled with wonder just by looking up at night.

“You kind of have to pick when you’re in Chicago what kind of experience you want,” she says. “It’s too bad we can’t see the night sky and also be around technology and a lot of lights, too.”

We asked astronomers and stargazers to tell us where Chicago’s good stargazing spots are. They all told us the same thing: nowhere. Not in the city or in Chicago’s near suburbs. But, some spots are better than others, and you’re better off getting as far from the city as possible. Adler astronomers and members of the Chicago Astronomical Society promised visiting a few of their favorites is worth your time. (Assuming there are no clouds, of course!) We’ve listed their suggestions below, from least-worst to OK. Consider the list your invitation to catch a bustling display of stars, constellations, meteors, and galaxies you’re denied each evening!

Before you leave

Bad timing can break a stargazing trip, so plan for both cloudless, moonless nights. Consult this handy clear skies chart for 3-day forecasts. Bring plenty of warm layers, a seat cushion or foam mat, water and snacks. Also, consider loading your phone with a neat stargazing app. (Options: Google Play store: http://wbez.is/1LrJcvo)

*Note: Our recommended stargazing spots fall on the Bortle Scale, which measures a sky’s darkness and light pollution. In this scale, a 1 is the darkest theoretical sky, and a 10 would render stars invisible.

In the city

Where: Northerly Island

Why: It’s slightly east of the Loop, and that slightly cuts down the light pollution.

How: Point your eyes or telescope east over Lake Michigan. The sky will be a tad darker than it would if you were facing the glow of downtown.

Bortle Scale: 8-9

Other suggestions: Adler Planetarium staff and other volunteers organize stargazing meetups through their  ‘Scopes in the City program, where you can gaze at Chicago’s night sky through telescopes in various places around the city. For indoor stargazing, Adler’s Doane observatory has the largest telescope in Chicago. (It’s becoming more accessible to the public as renovations are completed.) The University of Chicago’s Ryerson Observatory is another option, but call in advance.

The suburbs

Where: Openlands Lakeshore Preserve, Highland Park

Why: It has few lights! This 77-acre nature preserve lies along the Lake Michigan shoreline, 25 miles north of Chicago. It officially closes at sunset, but the Chicago Astronomical Society sometimes gains permission to host stargazing meetups there.

Bortle Scale: 6-7

Where: The Little Red School House, Willow Springs

Bortle Scale: 6-7

Where: Cantigny Park, Wheaton

Bortle Scale: 7

Other options: For indoor stargazing, Northwestern University’s Dearborn Observatory is open to the public on Fridays.

Beyond the suburbs

Where: Indiana Dunes State Park

Why: This park promises some of the metro region’s darkest skies; its 21,000  acres of wetlands and dunes are mostly unlit, and the darkness of Lake Michigan lies just north. It’s within an hour’s drive of Chicago and is accessible by public transportation, too, though a commuter train trip can take twice as long as a car ride. Under the right conditions, many stars are visible and you can clearly see the hazy patch of the Milky Way above the horizon.

How: The park is open until 11 p.m. To stay later, consider camping, which is possible year round. The park holds special stargazing events, some of which involve sleep-overs on the beach.

Bortle Scale: 4-5

Where: Silver Springs State Park, Yorkville (about 90 minutes southwest of Chicago)

Bortle Scale: 5

Where: Coral Woods Conservation Area, Marengo (about 90 minutes northwest of Chicago),

Bortle Scale: 4.5-5

Lake Michigan!

Where: Ferries start from Milwaukee or Manitowoc, Wisconsin. From Milwaukee, catch a night ride with the Lake Express that cuts right across Lake Michigan to Muskegon. The S.S. Badger departs from Manitowoc.

Why: The trips can take approximately 3 ½ hours. About halfway through, you’ll see the best stargazing in the area! The Milky Way is bright enough to cast shadows onto lighter objects. Some stars appear red or yellow, others blue, while others are white.

How: Head to the top deck about 90 minutes into the voyage. The ferries move quickly, so be warned that the pinnacle of darkness doesn’t last long. Bring layers because it gets windy!

Bortle Scale: 2-3.

Can we suggest a sailboat?

If you have a boat (or have a friend with one), you’ll be surprised to find how many stars you can see even just 10 miles due east of the city and northern suburbs. While looking back at the view of Chicago’s skyline could be tempting, give yourself about 15-20 minutes to gaze out into the darkness to adjust your eyes, too. Here’s a look at our own trip, and be sure to listen to our audio story which takes place on board!
