After analyzing some New Horizons images of Pluto, scientists found a supervolcano likely erupted on the planet as recently as a few million years ago.
Reference Pluto was once considered the ninth planet in the solar system, it was demoted in 2006 to dwarf planet status. We explore this icy body in more detail here.
The icy volcanism of Pluto's moon Charon may be driven by an internal frozen ocean erupted through a thin shell.
Reference Pluto, officially a dwarf planet, has surprising complexity on its surface. While certainly a world, not everyone agrees it is a planet.
For planetary scientist Alan Stern, witnessing the 20th century deep sea sarcophagus that is the Titanic serves up analogies to spaceflight.
Here's how to observe these solar system worlds overnight Wednesday (July 20) and Thursday (July 21).
The red cap on Pluto's moon Charon results when ultraviolet light and the solar wind interact with hydrocarbons and turn them into a soup of organic compounds dubbed tholins.
"Comet," "star" and "planet" are category names that immediately tell you something important about what they describe.
Pluto is lucky to exist in the orbit that it does, according to new computer simulations that show how the dwarf planet skirts near a chaotic orbit that could potentially destroy the beloved world.
