AstronomyLots of Tatooine-like planets around binary stars may be habitable
A new simulation suggests that planets orbiting a pair of stars may be plentiful, and many of those worlds could be suitable for life.

AstronomyNew data show how quickly light pollution is obscuring the night sky
Tens of thousands of observations from citizen scientists spanning a decade show that the night sky is getting about 10 percent brighter every year.
