Globe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations. It's easy to get involved - all you need is computer or smart phone & follow these 6 Simple Steps!
Note: The Globe at Night website is currently having some technical issues that are being worked on. We realize that many of you would like to submit measurements and are frustrated by your inability to do so. Please hold onto your observations and submit them in the near future when we are able to bring the website back and accept them. Thank you for your understanding.
Join us for the December, 2022 campaign!
We are off to a great start this year with 19,234 observations so far! Help us reach our goal of 20,000 data points for 2022!
Pegasus, the winged horse ridden by Perseus to rescue Andromeda from the sea monster Cetus is easiest to find during Autumn. The easiest way to find Pegasus is to look overhead and find the great square of Pegasus found adjacent to the milky way. This great square is the body of Pegasus and the body and head extend outwards.
SciStarter and Arizona State University created a customizable citizen science kit with everything needed for patrons to engage in Globe at Night. Access all the materials and details at SciStarter.org/Library-Resources
