Titan’s atmosphere recreated in an Earth laboratory
Beyond Earth, the general scientific consensus is that the best place to search for evidence of extraterrestrial life is Mars. However, it is by no means the only place. Aside from the many extrasolar planets that have been designated as “potentially-habitable,” there are plenty of other candidates right here in our solar system. These include the many icy satellites that are…

Can super-Earth interior dynamics set the table for habitability?
New research led by Carnegie’s Yingwei Fei provides a framework for understanding the interiors of super-Earths—rocky exoplanets between 1.5 and 2 times the size of our home planet—which is a prerequisite to assess their potential for habitability. Planets of this size are among the most abundant in exoplanetary systems. The paper is published in Nature Communications.
