Dusty alien planets could be more likely to harbor life, study suggests

Dusty alien planets might have a better chance at harboring life, a new study suggests.

Scientists studying the potential habitability of alien worlds look at a number of key factors, including temperature and composition (is it a rocky planet? Is it gaseous?). But in a new paper, scientists explore one often overlooked variable that could indicate whether life could exist on an exoplanet: dust.
