Twinkle, Twinkle Fading Stars, Hiding in Our Brighter Skies

From an AP story by Christina Larson headlined “Twinkle, twinkle fading stars: Hiding in our brighter skies”:

Every year, the night sky grows brighter, and the stars look dimmer.

A new study that analyzes data from more than 50,000 amateur stargazers finds that artificial lighting is making the night sky about 10% brighter each year.

That’s a much faster rate of change than scientists had previously estimated looking at satellite data. The research, which includes data from 2011 to 2022, is published Thursday in the journal Science.
