Noctalgia (sky grief)
As human inhabitants has elevated, and as synthetic lights have unfold throughout Earth, the celebs have been disappearing. And now astronomers have proposed a brand new phrase to explain their disappointment over the lack of darkish nights. The phrase they suggest is noctalgia (sky grief), from an earlier phrase solastalgia, the lived expertise of negatively perceived environmental change (with noct being a root phrase which means evening). In a late August 2023, in an open letter to the journal Science (pdf here), astronomers Aparna Venkatesan of the College of San Francisco and John C. Barentine of Darkish Sky Consulting wrote:
Our diminishing means to view the nighttime sky as a consequence of quickly rising human-made light pollution is a part of the palpable keening [a loud wailing or lament] of all that’s passing every day …
The letter goes on to say:
We provide right here the time period noctalgia to precise ‘sky grief’ for the accelerating lack of the house surroundings of our shared skies, a disappearance felt globally and deserving its personal discipline of research of ‘nyctology’ [the study of night matters].
What are we dropping?
You might need observed for your self that you simply don’t see as many stars as you used to. A 2021 report from NPR said that 99% of individuals within the U.S. and Europe reside below light-polluted skies.

That’s been true for many years. Nevertheless it wasn’t true for tens of millions of years earlier than that. What implication does the lack of the evening sky have on our collective psyches?
Venkatesan and Baretine’s letter mentioned:
This represents way over mere lack of surroundings: we’re witnessing lack of heritage, place-based language, identification, storytelling, millennia-old sky traditions and our means to conduct conventional practices grounded within the ecological integrity of what we name house. … As most cyclical indicators involving migratory birds/animals, climate patterns, pollinators and native vegetation are more and more altered with local weather change, the skies successfully signify a final stand of heritage, calendaring, language and meals sovereignty for a lot of world communities.
What can we do?
Gentle air pollution can be reversed, by way of schooling, consciousness and a willingness to behave. The letter mentioned:
How can we invite collaborative options within the face of this unprecedented risk to the skies, when so many in 2023 are experiencing disaster fatigue and younger persons are dropping hope for the planet’s future? … A number of the subsequent steps could possibly be: increasing such protections and globally coordinated home and worldwide insurance policies for the skies; designation of the skies as intangible cultural heritage by the United Nations; and, increasing the language/protections related to Earth jurisprudence and the ‘Rights of Nature’.
