You can help measure light pollution in British Columbia’s night sky using your smartphone

The Royal Astronomical Society of Canada wants people to download the Loss of the Night app and report what they see

VANCOUVER (NEWS 1130) – The late astronomer Carl Sagan might have put it best: “The total number of stars in the universe is larger than all the grains of sand on all the beaches of Planet Earth.” And this Saturday is a great day to ponder the endless cosmos – Oct. 5 is Astronomy Day.

To celebrate, you can help measure light pollution in British Columbia’s night sky using your smartphone.

The Royal Astronomical Society of Canada is encouraging people to download the Loss of the Night app and use it to measure the brightness of stars through the first week of October.

You can then email your results to the society to help them track how much light is obscuring our night sky.

The results, from around the world, are used to demonstrate how light pollution is impacting different areas of the globe. You can see the worldwide results on the Loss of the Night website.
