A new mathematical model provides insights into what may lie under the icy surface of the most famous dwarf planet: Pluto. Sputnik Planitia, the scientific name of its heart, looks dramatically ...

During observations of Pluto, an astonishing discovery gradually emerged—there seems to be ice volcanoes on Pluto. This ...

When the NASA’s New Horizons spacecraft buzzed by Pluto last year, it revealed tantalizing clues that the dwarf planet might have — or had at one time — a liquid ocean sloshing around under its icy ...

An ocean of liquid water deep beneath the icy surface of Pluto is coming into focus thanks to new calculations by Alex Nguyen, a graduate student in earth, environmental and planetary sciences in Arts ...

At the vast edge of the solar system, Pluto has long been perceived as a cold and lonely dwarf planet. However, a recent groundbreaking study has revealed that it may have had an extraordinarily fiery ...

When NASA's New Horizons spacecraft first snapped photos of an unusual heart-shaped scar on Pluto in 2015, the new view bolstered theories that the frigid world harbored an underground ocean.

The accretion of new material during Pluto’s formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day, despite the dwarf planet’s ...

Today, the dwarf planet Pluto orbits the sun from the edge of our solar system and its surface temperature is an inhospitable negative 378 to negative 396 degrees Fahrenheit. But a new study suggests ...

Yet Pluto has some geological oddities — in particular, a large number of cracks discovered on the far side — that add support to the existence of a hidden ocean, and even shed light on how it formed.

Some scientists also believe there is a liquid ocean beneath Pluto's ice shell that is estimated to be 249 miles thick. But they thought it formed later in Pluto's history as radioactive elements were ...
