What is the maximum number of moons that Earth could have?

In a recent study published in Earth and Planetary Astrophysics, a team of researchers from the University of Texas at Arlington, Valdosta State University, Georgia Institute of Technology, and the National Radio Astronomy ...

An orbital dance may help preserve oceans on icy worlds

Heat generated by the gravitational pull of moons formed from massive collisions could extend the lifetimes of liquid water oceans beneath the surface of large icy worlds in our outer solar system, according to new NASA research. ...

Tides could be source of heat on icy moons

The icy moons in the outer solar system hold the potential for life, given that they may contain oceans of water. But life also needs a source of energy input to perform essential functions such as growth, reproduction and ...

Underground magma ocean could explain Io's 'misplaced' volcanoes

Tides flowing in a subsurface ocean of molten rock, or magma, could explain why Jupiter's moon Io appears to have its volcanoes in the "wrong" place. New NASA research implies that oceans beneath the crusts of tidally stressed ...
