"Light Pollution: Astronomers Introduce 'Skylight Grief' to Describe the Painful Loss of Dark Skies"

Astronomers have coined a new term, "noctalgia" or "sky grief," to describe the pain associated with the loss of access to the night sky due to light pollution. The excessive use of electricity for lighting, including the growing number of satellites in orbit, has contributed to the increasing brightness of the sky worldwide. This loss not only affects cultural traditions and human imagination but also disrupts the circadian rhythms of nocturnal species. Efforts to combat light pollution include creating dark-sky reserves and implementing night-friendly lighting, while addressing satellite-based pollution requires international cooperation and pressure on companies like SpaceX.
