There are five simple steps to participate: 

1. Choose a group in another country by zone:

Using geographical longitude as a reference the Earth is divided into ten equal segments, each one spanning 36 degrees of longitude.  Countries in each of these 10 segments will have a period of three days to collaborate and plan an event together. Often times it is impossible to arrange an event due to weather so astronomers are welcomed to join another time zone to achieve the StarPeace goal.  In some cases, groups have participated in all three nights with various and different people each night.

Starting at 180 degrees longitude – also known as the International Dateline, StarPeace will proceed westward in 3-day increments.  So, countries located between 180 and 144 degrees east longitude will pick a night from April 1st to April 3rd for their public star party.  Countries located in the next zone between 144 and 108 degrees east will have the April 4th through 6th dates and continue to proceed around the globe.  When it is all said and done, the whole month of April will have countries crossing their borders and sharing their night time sky with each other. Listed below are the dates and zones for the countries moving westward from 180 degrees from the International Dateline.

2. Make a Connection - Find a StarPeace group in another country:

You can view the zones below to gather the information you will need for the form.
You MUST be logged in, and be the administrator of an Affiliate Group to complete the form.
Once approved, you will be paired up by the 30NSP team. If you have additional question, please contact [email protected]

3. StarPeace Communication Planning:

Hot spots, laptops, cell phones, mobile devices, webcasts, video cameras, Skype and Google Hangouts, are ways that groups can connect. If live sessions cannot be done, groups can tweet, or post pictures and comments on Facebook.  Some groups have talked on cell phones during their events, which is also a great way to reach over a border. In some countries, they do not have reliable Internet or cell phone coverage, so in some cases it's okay not to have live communication, but you could post photos on social media after the star party. Be creative! 

4. The star parties happen with lots of communication between groups! 

5. Reporting Results: Stay tuned for instructions on reporting.

Helpful Hints:

1. Make sure (some) astronomy club members have binoculars and telescopes.

2. Secure a dark spot for your event – the darker the better.

3. Spotlight the main objects like the moon, and planets.  Of course add in a few clusters and galaxies if you can.

4. Make sure your public knows they are going to be part of an international mission and let them know what countries they will be joining that night.

5. Have information on these objects and the countries participating, and offer the crowd some wonderful facts and information on what you are showing them.

6. Get the word out and encourage other groups and the media to join you.

7. For virtual star parties, spread the word on how to use Google Hangouts, Skype and other live connecting software.

Share your experience and your stories:

Since there is no other project like this it is important to share your experiences with the world. Share your event images with us during your zone period via Facebook or the Flickr group or Tweet using #StarPeace hashtag. Follow @gam_awb and @starpeace to keep updated on events around the world.

The Discover the COSMOS Challenge is a great opportunity, open to teachers, trainers, and students from all over the world. Read more

StarPeace began in 2009 as one of the Special Projects of the International Year of Astronomy. The goal has and will continue to be a call for peace from the four corners of the world, while sharing a song of love for the boundless and borderless sky.
