The exhibition gives stargazing tips for any location—such as getting near water, finding open spaces and seeking high ground—along with prompts for features to look for in the night sky. It also features gorgeous images of protected dark-sky sites around the world and a map so visitors can discover where they, too, can experience such starry nights.

Every day, the world’s largest migration takes place in the ocean, cycling nutrients and carbon. Across the globe, a diverse group of organisms come up to the ocean’s surface at night to feed, then move down to darker waters during the daytime to escape predators. Vertical migrators represent a wide array of marine life, but the dominant groups include fishes, jellies, shrimp and squid. Artificial lights at the ocean’s surface attract some organisms and repel others, potentially altering food webs and disrupting the carbon cycle that the planet depends on.

The bright, unshielded lights along this street can make it hard for drivers to notice pedestrians amid the light clutter. Lights are often associated with safety because they are meant to help see and assess risks. But sometimes lighting only makes people feel safer. Poor lighting design can actually reduce safety by making people and objects more difficult to spot. “Lights Out” will examine the many ways that artificial light associated with human activity—from city lights to energy production to roadways—can have unintended consequences.

The Birth of the DarkSky Chicago Chapter By Adam Kreuzer The four of us started this chapter of DarkSky International with the shared goal of restoring and protecting dark skies. We all cherish memories of dark skies from the past. For me, there were dark nights with high school friends in fields of corn, and nights laying on cool sand, barefooted, with my son, Ben. Rippling waves washing the shore. Moonshine on the water. The occasional shooting star. Memories that will live with me forever. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/aec96686-6276-456e-b677-df765c75f400/starry-night-print-by-vincent-van-gogh-vincent-van-gogh.jpg Memories - Make it stand out Vincent van Gogh painted Starry Night in 1889 during his stay at the asylum of Saint-Paul-de-Mausole near Saint-Rémy-de-Provence. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/d80280ae-a3a9-42fa-b5d8-d330dd5b24b2/Screen+Shot+2023-04-20+at+10.53.28+AM.png https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/e10bd94d-dc96-4877-9a3c-f25498815d01/download+%283%29.jpg https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/bb5d40a0-e13e-4439-8902-3f9e6850015b/nprlogo_rgb_whiteborder_custom-7c06f2837fb5d2e65e44de702968d1fdce0ce748.png https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/7687a148-cf17-45cc-9570-768db9f5af92/jerry-zhang-lH40asdVljs-unsplash.jpg Memories - Remember Lightning Bugs? Much like the stars and planets, fireflies are dwindling due to night-time light pollution. During the last couple of years during the pandemic, IDA delegate Adam Kreuzer sent his neighbors a series of letters about how they can help these little sparks of joy and other creatures return to our backyards. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/7c931861-9433-471d-a22f-9f48909dfc0f/Screen%2BShot%2B2023-02-16%2Bat%2B2.27.05%2BPM.png Memories - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/2f4bd4b1-791c-4bec-ac33-00ac9304a444/IDA%2Blove%2Bsky.jpeg Memories - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/724b56e5-b0b7-441e-adda-76f23f333341/IMG-7031.jpg Memories - Make it stand out Read Valerie Blaine’s blog post: Kill the Lights, Save the Birds https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/3c6956ce-ccf1-41a9-96f0-74e540a19d5c/max-kleinen-9Xmr8baomb0-unsplash.jpg Memories - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/869f38c7-d89a-444d-b314-9b9d135b16bd/Screen%2BShot%2B2023-02-16%2Bat%2B2.26.54%2BPM.png Memories - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/a207649a-807b-4559-8188-c6b5bf2a54e1/Fireflies.jpg Memories - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.idachicago.org/make-a-donation daily 0.75 2023-08-21 https://images.squarespace-cdn.com/content/v1/608327c820d2470c7807f11b/a9ce5def-9b34-427a-8513-fa17f3ae4af8/donate-hero.jpg Make a Donation - Our ability to observe and comprehend the universe allows us to marvel at its wonders, unravel its secrets, and seek our own purpose within its boundless expanse.
