Researchers have recreated the chemistry of atmospheres on distant planets for the first time in the lab, according to two new papers. They found that hazes, such as the hydrocarbons that shroud Saturn's moon Titan, can be produced on a class of exoplanets known as super-Earths and mini-Neptunes. Chemical hazes and clouds can influence surface temperature and the potential for a planet to support life. The work can help guide future studies. (BBC News)
