Stars Above Horizon
iOS Universel / Education
We are interested in the visibility of stars for the naked eye. How much influence does the background brightness have? What is the exact influence of the air mass close to the horizon, its humidity and temperature on the visibility of stars? Does it dependent on the geographic latitude (i.e. the climate of the region) and how big is the range of human eyes’ visible abilities?
We do not collect personal data, we are only interested in the broad overview of the range of human eyes. So, please participate as often as you can and wish, at most various geographic places - on holidays and other travels, at home while camping, barbecuing or simply enjoying a summer evening, in big cities as well as in the country side. The app and data are not personalized, so feel free to invite your friends and family to participate in the same observational session or use the app on the same phone.
Please keep in mind that you will upload scientific data! So, feel free to take it as a challenge but please stay honest in uploading only real data!
Quoi de neuf dans la dernière version ?
- It is now possible to view the northern hemisphere of the sky from the horizon to the zenith! This can help you to recognize star patterns with greater certainty.
- You can now tell us in which color you perceive a certain star. Simply press and hold on a previously selected star and a color selection will appear. You will then see the color you selected in the star map.
