Dear Curator....

We invite your arts organization to join schools, art museums and educational organizations all around the world by taking part in SkyDayProject
SkyDayProject is an evolving experience. It begins as a citizen artwork in which people contribute their vision of the sky to the global SkyDayProject mosaic and then it becomes an interactive educational platform about the science of all things sky.

SkyDayProject is interactive. Within it viewers can find their own group's gallery, click on any photo to enlarge it and filter it by country, mood (blue sky, grey sky, night sky etc.) and number of images. Soon we will be linking educational content to it for all ages grade school through college. (For example, this short video for middle schoolers about Why is the sky blue? created for us by a student of Daniel Horton's in the Department of Earth and Planetary Sciences at Northwestern University.

So have your community join in!  Its free and easy to take part. Exhibiting the project is easy too. Just connect any screen to and we encourage creativity in the sharing of it!  To set up your own group in the mosaic please just fill out our form and we will get back to shortly with details on how/when to tweet your sky photos.

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 for tweeting 24/7 and 365 days a year and many organizations use the weeks running up to Sky Day and after to participate.  Whatever works for you!

How does participation work? 

Participation is free. Simply sign your group up with us and inviting your community to take part.  Heres how we invite groups 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 it's 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 three golden rules:

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 plabene 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!   

Golden Rule #2 - Remember to tweet your sky photos using BOTH hashtags given to you

Golden Rule #3  Have a great time doing it :)  

How do we view Sky Day Project?
Sky Day Project is live at and is interactive. You can view the entire world's participation or find your own group and even filter it by different sky 'states':

Blue Skies - can offer amazing transitions of light!  Can you catch them?                                     Clouds - amazing possibilities!
Transitions - Day to night. Night to day.
Storms - Here's a creative challenge. Can you convey the idea of a storm without showing its impact on objects (like trees, people, etc.)?
Night time - stars, moons, eclipses - spectacular!

All skies are welcome!  (Why wouldn't they be?)  

How do we exhibit Sky Day Project?
It's as easy as connecting a screen/projector up to the url. 

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 our Sky Team - NASA astronaut and artist Nicole Stott, Northwestern University climate scientist Daniel Horton, University of Illinois climate scientist and lead IPCC author Don Wuebbles and a team of super talented volunteers.
