Wind farms and light pollution:
Medium-intensity turbine lights can be brighter than the brightest stars and planets on the night sky up to significant distances. This should be taken into account in environmental impact assessments.

🦇 New paper out in @jappliedecology.bsky.social!

🚨 Red aviation lighting contributes to attraction of bats towards wind turbines but ADLS (Aircraft Detection Lighting System) can reduce this behaviour and thus potentially collision risks

According to SpaceX, on Dec 17 one of the Group 11-30 satellites, Starlink 35956 (66629, 2025-271N), suffered a failure
with venting of the propulsion tank and release of some debris objects. This is reflected in a 3km dip in the orbit tracking seen here

"The [SpaceX] statement raises questions about whether the satellite experienced a minor explosion or was struck by something. It also suggests the satellite can no longer maneuver with its built-in propulsion, even if contact is re-established."

Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)

Minimizing aviation lighting duration reduces bat attraction to wind turbines
This study provides empirical evidence that attraction behaviour of bats towards wind turbines is driven, at least partially, by red aviation lighting. We also demonstrate that smart lighting of wind....
