Sky Day Project FAQs

When is Sky Day? 
Sky Day is September 21st (each year) and this is when most people take part in Sky Day Project. But that doesn't mean you need to limit your participation to just that day. Sky Day Project is open 24/7 and 365 days a year and many organizations use the weeks before (or after) to take part.  Whatever works for you 

Who takes part?  
Chicago's Adler Planetarium/The Staerkel Planetarium/ Delaware Contemporary/Cloud Appreciation Society (UK)/Lycee Claudel (Canada)/Northwestern University/Jeddah Astronomy Society/American Montessori Society/Institute of Environmental Science for Social Change (Philippines)/Australian Meteorological and Oceanographic Society/The Chicago Botanic Garden to name a few.

Talking of the Adler Planetarium, Annie Vedder and her team created a beautiful installation there last year over Sky Day weekend!  See below:

How does participation work? 

Simply sign up with us (its free) and inviting your community to take part.  Posting of photos is done via Twitter or by posting directly to the website

Heres how we invite people to take part:

Grab a phone (or any device with a camera) and find a place where you can really experience our sky!  Use your creativity and your vision to document its dynamic changes in photography while you reflect on what our sky means to you. Make it your own!  No-one sees the sky quite like you do. Just remember our ONE golden rule:

Golden Rule #1 - Make it ALL about the sky. The challenge is to take yourself somewhere where you can photograph just sky - NOTHING else. Not always so easy nowadays, right?  Clouds?  Yes!  Sun, moon and stars? You bet!  Is it ok if there is a little plane up there or a flock of birds? Sure!  If you can see it when you look up, that's what we're interested in!  But pictures with twigs, lamp posts, buildings, people... etc., those photos will get snagged in our filters and won't get in.  So crop those elements out!   

How do we view SkyDayProject?
SkyDayProject is live on-line at and is interactive check out the 'Refine Gallery' menu 

How do we exhibit Sky Day Project?
It's as easy as connecting a screen/projector up to the url.  See above installation at the Adler Planetarium.

How many photos can we tweet? 
As many as you like!  And everyone you tell your group's tags to can tweet their sky photos from any device 

Our Organization
Artist Ben Whitehouse created Sky Day and Sky Day Project to bring people of all ages together to learn about our sky, how it functions and what it's vulnerabilities are and come together across cultures and borders in a new spirit of ecological citizenship.  He is joined in this effort by amazing astronaut and artist Nicole Stott, Northwestern University's awesome climate scientist Daniel Horton and University of Illinois superstar climate scientist and lead IPCC author Don Wuebbles. With the input of artists and scientists we are building an interactive educational platform to offer schools, parents and kids inspiring ideas, innovative projects and exciting opportunities for international collaboration.
