The findings of a study in Nature Climate Change show that artificial light at night disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments. go.nature.com/44cCKWm 🧪

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative

Australia has so much solar that it's offering everyone free electricity
Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

The VLT lasers create artificial stars by exciting sodium atoms in the atmosphere, at about 90 km altitude.
This allows the telescope to learn how to adjust for atmospheric turbulence to obtain sharper images.
