Let There Be Night
Go straight to my website
Let There Be Night is a student experiment that asks, "How much of the night sky have we already lost?" Thousands of students assessed the quality of the night sky in their community concurrent with the Globe at Night program. A team of students then built a 3D model from 35,000 LEGO® blocks to share their findings with the public.
I coordinated Let There Be Night in 2009, the International Year of Astronomy, with collegue Art Klinger of the PHM Planetarium. I've built the Let There Be Night website at www.lettherebenight.com.

A community assesses how much of the night sky has been lost to light pollution.

Simple activity illustrating glare, light trespass, and sky glow shows how light pollution can be remedied by shielding outdoor lights. More at
