Over the past decade, researchers have been puzzling through Pluto’s mysteries. Meanwhile, the New Horizons probe heads for interstellar space.

At the far reaches of our Solar System lies Pluto, a mysterious world shrouded in shadows and icy terrain. NASA’s latest ...

New photos taken by NASA’s New Horizons spacecraft reveal a disarray of geographic features including soaring mountains, icy plains, and possible dunes.

The images also show a remarkable variety of colors across Pluto's surface, which could indicate complex organic materials or compounds reacting to the planet's weather patterns and environmental ...

New close-up images of Pluto from NASA’s New Horizons spacecraft reveal a bewildering variety of surface features that have scientists reeling because of their range and complexity. Image: This ...

The James Webb Space Telescope (JWST), operated by NASA, has uncovered intriguing new details about Charon—Pluto’s largest ...

Almost 10 years ago, a NASA spacecraft was able to take several photos of Pluto, known for decades as a planet before it was reclassified as a dwarf planet in 2006.

New images also show the most heavily cratered—and thus oldest—terrain yet seen by New Horizons on Pluto next to the youngest, most crater-free icy plains. There might even be a field of dark ...

This tells us some other type of process must be making Pluto's surface geologically active. One theory is that radiation in the planet keeps it warm and active.

Scientists expected Pluto to be heavily pocked with craters, i.e. from billions of years’ worth of pummeling by space rocks. Instead, they discovered the dwarf planet’s surface — at least,what they’ve ...
