Hal Weaver, the mission project scientist, said even at Pluto's vast distance from the sun, very slight temperature variations can produce polar caps. "The polar cap is a region that's normally a ...

NASA’s New Horizons probe has picked up a bright spot on Pluto's surface that may indicate a polar ice cap, as it zooms towards its close flyby this summer. The latest images from the almost ...

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 ...

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 ...

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 ...

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 ...

Pluto and Charon with Pluto's rotation axis shown. The bright spot at the right is a possible polar cap. Credit: Besides those dark and bright regions, there's a bright area at one of Pluto's poles.

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

New Horizons scientists interpreted the data to reveal the dwarf planet has broad surface markings – some bright, some dark – including a bright area at one pole that may be a polar cap. “As we ...
