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!
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.
The October 2021 campaign is using the Constellation Pegasus. Check out the dates and constellations for our other campaigns during all 12 months of 2021.
