The Negative Impacts of Artificial Light on the Universe

Satellite tracks sometimes appear in astronomical images which being taken you have these bright streaks going all the way across. And this is a problem that's only set to get worse not just as countries industrialised further but development into space and the satellites that orbit the earth. It has serious implications down here on earth as well. Migratory birds for example rely on visual cues of when day becomes night to trigger certain behaviours which artificial light at night can disrupt.
