"Tidal heating plays an important role in the heating and orbital evolution of celestial bodies," said Alex Hayes, professor of astronomy. "It provides the warmth necessary to form and sustain ...

What is the habitability potential on Saturn’s moon, Enceladus? This is what a recent study published in The Planetary Science Journal hopes to address as a team of researchers investigated a ...

A team of volcanologists and planetary scientists from NASA's Jet Propulsion Laboratory, California Institute of Technology, the University of Arizona, and Arizona State University has found via study ...

Tidal heating is the major source of heat in the outer Solar System. Because of its strong tidal interaction with Jupiter and the other Galilean Satellites, Io is incredibly volcanically active. We ...

Astronomers searching for rocky planets that could support life in other solar systems should look outside, as well as within, the so-called “habitable zone,” University of Arizona planetary ...
