The Dark Side of Pluto

During its departure from Pluto, New Horizons used its LORRI camera to image a portion of Pluto's southern hemisphere that was in a decades-long seasonal winter darkness, but still very faintly illuminated by sunlight reflected by Charon.

Existence of subsurface oceans on the satellites of the giant planets and Trans-Neptunian objects has been predicted for some time.

When Pluto passed in front of a star on the night of August 15, 2018, a Southwest Research Institute-led team of astronomers had deployed telescopes at numerous sites in the U.S. and Mexico.

SOFIA observed the occultation by Pluto of a bright star on 29 June 2015, enabling scientists to measure pressure, density, and temperature profiles of the atmosphere of the dwarf planet.

Beyond the orbit of Neptune, a diverse collection of thousands of dwarf planets and other relatively small objects dwells in a region called the Kuiper Belt.

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth.

The accretion of new material during Pluto's formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day, despite the dwarf planet's orbit far from the sun in the cold outer reaches of the solar system.

Observations made with the Stratospheric Observatory for Infrared Astronomy (SOFIA) -- a Boeing 747SP jetliner modified to carry a 106-inch diameter telescope -- help explain how Pluto's haze is formed and how the distant Sun affects the dwarf planet from 3.7 billion miles away.

Pluto's Icy Heart Makes Winds Blow

A "beating heart" of frozen nitrogen controls Pluto's winds and may give rise to features on its surface, according to a new study.

A gassy insulating layer beneath the icy surfaces of distant celestial objects could mean there are more oceans in the universe than previously thought.

Evidence for Ancient Glaciation on Pluto

A letter authored by SETI Institute scientist Oliver White was published by Nature Astronomy today. Co-authors included researchers Jeff Moore, Tanguy Bertrand and Kimberly Ennico at NASA's Ames Research Center in Silicon Valley.

Heat generated by the gravitational pull of moons formed from massive collisions could extend the lifetimes of liquid water oceans beneath the surface of large icy worlds in our outer solar system, according to new NASA research.

The gas composition of a planet's atmosphere generally determines how much heat gets trapped in the atmosphere.

Video Depicts Flyover Of Pluto

In July 2015, NASA's New Horizons spacecraft sent home the first close-up pictures of Pluto and its moons - amazing imagery that inspired many to wonder what a flight over the distant worlds' icy terrain might be like.

New Insight Into Pluto's Bladed Terrain

Using a model similar to what meteorologists use to forecast weather and a computer simulation of the physics of evaporating ices, scientists have found evidence of snow and ice features on Pluto that, until now, had only been seen on Earth.

Modeling Pluto's Icy Heart

Pluto's "icy heart" is a bright, two-lobed feature on its surface that has attracted researchers ever since its discovery by the NASA New Horizons team in 2015

Pluto's Icy Slushy Heart

Beneath Pluto's "heart" lies a cold, slushy ocean of water ice, according to data from NASA's New Horizons mission.

The next target for NASA's New Horizons mission -- which made a historic flight past Pluto in July 2015 -- apparently bears a colorful resemblance to its famous, main destination.

Explaining The Red Color On Charon

In June 2015, the cameras on NASA's approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto's largest moon, Charon.

Pluto's Methane Snowcaps

The southernmost part of Pluto that NASA's New Horizons spacecraft could "see" during closest approach in July 2015 contains a range of fascinating geological features, and offers clues into what might lurk in the regions shrouded in darkness during the flyby.
