How to Spot the International Space Station
Every summer, Michelle Larson, President and CEO of the Adler Planetarium, loves to attend a star party (or two!) with her family. Star parties are one of those scenarios where groups of people get together and camp out in a place where the night sky is highly visible. People bring tents, blankets, hot chocolate… and […]

We are made of starstuff.” ― Carl Sagan Even if you’re just a novice space enthusiast, I’m sure you’ve heard some variation of […]
Keep Looking Up
If you receive a letter from me, it will likely end with my favorite call-to-action, “Keep Looking Up.” And, while some have interpreted this phrase to have optimism as its intention, I have a much more literal request in mind. Look Up. Yes, you. Right now. I’ll wait… Chances are you noticed something you hadn’t […]

Meet Spacesuit Designer Bob Davidson
Imagine you are called into a meeting about a job. The job is completely different from any job you’ve ever had. It’s not an anxiety dream—this is really happening!—so you do what any responsible, awake person would do: You tell the other people in the meeting you have no idea how to do this job. […]
All Over Earth, Collecting Rocks from Space
Header Image: This is probably the first Moon rock picked up by Neil Armstrong as part of the “contingency sample.” Because the collection was so hurried and the documentation sparse, NASA scientists are not completely sure of the identification.

Building Community Under the Stars
In September 2016, we—the Adler’s ’Scopes in the City team—brought a telescope to the Wrightwood-Ashburn library branch on Chicago’s southwest side and set it up in front of the library. This branch has a beautifully clear view of the sky with no tall buildings in the way. A teen involved in other library programs came […]

Setting: Tuesday, June 30, 1908, around 7:15 am. A remote forest near the Podkamennaya Tunguska River in Siberia. A large fireball streaks through the sky followed by an intense wave of heat felt up to 40 miles away. A loud explosion. The ground shakes. Silence. If the playwrights of today were to write a theatrical […]
