Globe At Night

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.

Can you find Hercules?

Hercules the hero of Greece can be best seen by looking up and to the North in the summer. Find the brightest star Vega by looking North, then by looking just west of that you can make out the keystone, or body, of Hercules. The head of Hercules will be to the South, and his kneeling legs will be pointing northward.

Can you find Scorpius?

Scorpius like Sagittarius is most easily found looking south toward the Milky Way and following it upward. It is easiest to find Scorpius by looking for what looks like a fish hooks of bright stars. At the center of this hook is what visually looks like a bright red star. This is often mistaken for Mars being visually red, but this is the Red Giant star Antares which is the heart of Scorpius. The body of Scorpius is what looks like the fish hook, with the tail as the hook and the head and pincers of Scorpius being at the opposite end making a three pronged end point away from Sagittarius.

How to report data?

Practice finding all the Globe at Night Constellations, when you are done practicing follow the 6 steps:

Go Outside

During the campaign dates, go outside more than an hour after sunset (8-10 pm local time). The Moon should not be up. Let your eyes become used to the dark for 10 minutes before your first observation.

Use App

Use a night sky app on your phone outside to find the constellation from where you are.

Open Form

Go to the Globe at Night Report page to start to enter Globe at Night measurements. Make sure you are in “Nighttime version”

Fill your location

With a smart phone, the app will put in the date, time, location (latitude/longitude) automatically. Otherwise please type them in. For your location, type the street address closest to your observation along with the city, state or province and country.

Choose the star

Choose the star chart that looks most closely to what you see toward your constellation. That is, what is the faintest star you can see in the sky and find in the chart?

Submit

Chose the amount of cloud cover at the time of observation and then click on the “SUBMIT DATA” button.
