Jupiter’s moon Europa is smaller than Earth’s moon yet may contain more than twice as much liquid water as all of Earth’s oceans combined. Scientists believe that under its icy

Press Release September 16, 2025 This is an artist’s model of an early Mars — billions of years ago — which may have had oceans and a thicker atmosphere. It

In the 1970s, the renowned physicist Victor Weisskopf famously developed a research program to qualitatively explain properties of matter in terms of the fundamental constants of physics. But there was

Deep Space Climate Observatory (DSCOVR) satellite’s EPIC maintains a constant view of the fully illuminated Earth as it rotates, providing scientific observations of ozone, vegetation, cloud height and aerosols in

Large enough to retain an atmosphere and drive geologic/hydrologic cycles, but not so massive that relocation is infeasible. This figure illustrates why planet size and escape velocity are critical factors
