Thousands of people are gazing up at the stars this month -- to help out with a science project. It's called the Great World Wide Star Count, and one of its objectives is to map worldwide light pollution.
Schoolchildren, and amateur scientists around the world are being encouraged to look for specific constellations and then post their observations online. Participants in the Northern Hemisphere will look for the constellation Cygnus, while those in the Southern Hemisphere will look for the constellation Sagittarius.

- Determine which constellation to observe.
- Find that constellation at night an hour after sunset (about 7-9pm local time)
- Match your nighttime sky with one of our magnitude charts
- Report what you see star count website
- View results of this international event.
