As NASA’s New Horizons mission heads to Pluto, scientists could get an idea of what to expect by studying Triton, Neptune's strange icy moon.

Since Pluto, Titan and Triton are all icy worlds with atmospheres rich in nitrogen, methane and carbon monoxide, researchers had thought they might all possess similar kinds of hazes.

A proposed "Neptune Odyssey" mission to explore the ‘other’ blue planet and its weird moon Triton is “shovel ready,” say scientists. It could be NASA’s next flagship mission.

Pluto and Triton, Neptune’s largest moon, have been considered siblings or cousins–both are small worlds with thin, nitrogen-based atmospheres and icy surfaces.

NASA's new Voyager 2 map and video of Neptune's moon Triton celebrate 25-year anniversary, as New Horizons heads to Pluto.

Unresolved debates about these bodies have gone on for decades. How do we square the apparent wind-blown features on Triton's and Pluto's surfaces with their thin, tenuous atmospheres?

Pluto is a Kuiper Belt object, just like Triton. The best images we have of Pluto so far – though they’re just blurry pixels – reveal that the frosty features on the world’s surface are ...

NASA's New Horizons mission is kicking off its climactic month of July with amazing views that clearly show Pluto's black spots and Charon's dark pole.

We present a 3D general circulation model of Pluto and Triton’s atmospheres, which uses radiative-conductive-convective forcing. In both the Pluto and Triton models, an easterly (prograde) jet ...

Triton is only slightly larger than Pluto (1,700 miles [2,700 kilometers] in diameter compared to Pluto’s 1,500 miles [2,400 kilometers]). Both objects have atmospheres primarily composed of ...
