Artificial satellites around the Earth are a new form of light
pollution. Those on low-earth orbits can be especially bright.
Companies plan to launch tens of thousands of such satellites, and our
view of the night sky, constellations and the Milky Way may be entirely
lost. Please sign the following petition, and share it with your friends (and
ask them to sign and share).

IAU statement from 2020 February,
saying that "The IAU considers the consequences of satellite constellations
worrisome", and "A great deal of attention is also being given to the protection of the uncontaminated view of the night sky from dark places, which should be considered a non-renounceable world human
