Pluto's days, though they drag on a bit at around 153 hours, are nothing compared to its years. Pluto's orbit takes 248 Earth ...

Using the James Webb Space Telescope, astronomers have discovered carbon dioxide and hydrogen peroxide at the surface of Pluto's largest moon, Charon, potentially shedding light on its origins. When ...

Giant, ridge-like structures of methane ice, known as "bladed terrain," may be much more abundant along Pluto's equator than previously realized, a new study suggests. When you purchase through links ...

Billions of years ago, in the icy outskirts of the solar system, a dramatic collision forged the unusual pairing of Pluto and its moon, Charon. This celestial dance defied expectations, birthing a ...
