There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

It seems like every day that astronomers discover another possibly habitable world, like Proxima Centauri b, our closest exoplanent neighbor, and TRAPPIST-1f, one of seven recently discovered Earth-sized planets orbiting the same star. But don't prepare for first contact just yet. It will be exceedingly complicated to figure out whether there's actually any life or potential for it on such planets, based on new research into our own evolving world. Chris Reinhard, an assistant professor in the School of Earth and Atmospheric Sciences, co-authored the study, which was published in Astrobiology.
