The researchers placed a (theoretical) duplicate of Earth inside so-called binary, or two-star, systems, and ran simulations on planetary axis tilts. The results indicate the planets would have tilts similar to Earth's, which bodes well for habitable climates that could potentially support alien life. There are a lot of multiple-star systems out there, so the study may boost the number of exoplanets that could harbor life. In addition to this CNET story, the study has also been covered in Daily Mail Online, King5 News in Seattle, and Express.co.uk. Li is an assistant professor in the School of Physics, while Quarles, the study's principal investigator, is a research scientist in Li's lab.
