Adopt-a-Constellation 2018 Matching Gift Challenge

2018 Adopt a Constellation

We are asking you to donate now to save our night skies through our 2018 Matching Gifts Challenge by "adopting" a constellation! When you adopt a constellation through your donation to IDA, you can choose the constellation that speaks best to your interests. IDA will send you a collectible card with information about your constellation and a certificate of adoption to commemorate your gift. 

  • Noctua “The Owl” represents the preservation of the natural nighttime environment for the health of Earth’s living things. 
  • Libra “The Scales” represents nature’s fundamental balance between day and night, light and dark.
  • Orion “The Protector” represents the ongoing fight to protect the night from light pollution.
  • Eridanus “The River” represents the historical use of rivers to connect people, and our travel toward a world without light pollution.

And don’t forget! Your donation to IDA will be doubled! A circle of IDA’s most dedicated supporters has pledged $85,000 in matching gifts to help us raise $170,000 to defend the night. When you give to IDA and adopt a constellation, your donation will be matched dollar for dollar. A gift of $50 becomes $100. A gift of $1,000 becomes $2,000.  

Please contribute today to help us continue the fight against light pollution. IDA’s success depends on your generosity – fully seven cents of every dime that supports our programs comes from caring and compassionate donors like you. This is why you are an essential partner in our shared mission to protect the night sky.


Thank you for your continued and generous support of IDA. 
We could not fulfill our mission to protect the night without your help.
