We now know Pluto much better, thanks to NASA's New Horizons mission, leaving CNET's Eric Mack to wonder how the former planet compares to our home rock. Eric Mack has been a CNET contributor since ...

Pluto's snow-capped mountains look like they belong on Earth, but researchers have discovered that the snowy tops of these features are actually made of methane frost. Pluto's snow-capped mountains ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed ...

Clyde Tombaugh noticed a speck of light that was Pluto in 1930. — -- Clyde Tombaugh is finally getting to visit the speck of light he spotted at the edge of the solar system in 1930. New Horizons ...

Pluto is an icy dwarf planet that usually lies beyond the orbit of Neptune in the Kuiper Belt. The dwarf planet is smaller than Earth's Moon, with red snow-capped mountains as tall as the Rockies.

Pluto landed its largest moon, Charon, with a 'kiss'—overturning decades of scientific assumptions about how planetary bodies form and evolve. This is the conclusion of a new study, conducted at the ...

Hubble spots white dwarf star 'snacking' on chunk of Pluto-like object. The NASA/ESA Hubble Space Telescope has spotted a ...

Using advanced models, SwRI led new research that indicates that the formation of Pluto and Charon may parallel that of the Earth-Moon system. In the resulting “kiss-and-capture” regime, Pluto and ...
