There are more than 200 moons in our Solar System, but their relatively small sizes make similarly sized extrasolar moons (exomoons) very hard to detect...
University of Washington researcher Baptiste Journaux and colleagues believe the newly-created substances could form at the surface and bottom of deep...
With thousands of discovered exoplanets and new missions that will explore our Solar System, the search for life in the Universe has entered a new era....
In their hunt for elusive exomoon candidates, astronomers have looked at 70 cool gas giants found by NASA’s Kepler space telescope. They’ve found only...
A team of astronomers in Japan has demonstrated that systems can form that have only one large moon, such as Titan around Saturn, around a gas giant.
