New images from the New Horizons probe approaching Pluto indicate it might have a polar cap of nitrogen ice, NASA says. The observation came in a series of pixilated images taken April 12-19 as ...

The first surface details start to come into view as NASA's New Horizons space probe speeds toward its summer rendezvous with Pluto and its moons. Freelancer Michael Franco writes about the ...

Here’s how it works. Scientists have figured out why Pluto's moon Charon wears a red cap. New laboratory work shows that the color results when ultraviolet light and the solar wind interact with ...

including one bright area that may be a polar ice cap, NASA said. Also seen in the images is Pluto's largest moon, Charon, rotating in its 6.4-day orbit. The photos were captured within 70 million ...

NASA's Pluto-bound New Horizons spacecraft has spotted surface features on the icy world, including a possible polar cap. With 97 million kilometres (60 million miles) left to go before its ...

Pluto may have a polar ice cap. This is the tantalising prospect revealed in the latest images to come down from the New Horizons spacecraft. The US space agency probe is en route to the dwarf ...

Charon, Pluto’s largest moon, wears a red cap. Charon’s north pole has a dark red color, starkly different from its otherwise gray-white surface, and scientists have finally found out why.

For the north pole of Pluto's largest moon, Charon, winter is always coming. And when it does, the dark polar night can last more than a century, with temperatures dropping toward absolute zero.

Scientists believe Pluto could have a polar ice cap, after analysing the first images received from the New Horizons spacecraft. Although the dwarf planet appears as little much more than a ...
