Planetary scientists at the University of Arizona say they have discovered an entirely new type of cosmic collision.
Pluto and Charon are the largest binary...
Using data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide...
Planetary researchers from Washington University in St. Louis and the Lunar and Planetary Institute have used mathematical models and unprecedented high-resolution...
Pluto’s surface is dominated by the huge, pear-shaped basin Sputnik Planitia. It appears to be of impact origin, but modeling has not yet explained its...
When ocean-bearing moons begin to cool down, their oceans can freeze. As new ice accretes to the bottom of the existing ice shell, the added volume of...
Cryovolcanoes (ice volcanoes) are similar to normal volcanoes but instead of being formed from molten rock, they are made by frozen liquids like ammonia...
University of Exeter’s Dr. Adrien Morison and colleagues have shown how vast ice forms have been shaped in Sputnik Planitia, a nitrogen-ice-filled basin...
The surface pressure on the dwarf planet Pluto is decreasing and that its nitrogen atmosphere is condensing, forming ice on the dwarf planet’s surface,...
1I/‘Oumuamua, a strange object of extrasolar origin discovered on October 19, 2017 by the Pan-STARRS 1 telescope, was small, about half as long as a...
The bright frosts observed in 2015 in the equatorial region of Cthulhu on Pluto are mostly made of methane-rich ice, according to new research.
This image,...
Using data from the PACS photometer onboard ESA’s Herschel Space Observatory, astronomers have found that thermal properties of the five major moons...
Pluto is thought to possess a subsurface ocean beneath its thick ice shell. It has generally been assumed that the dwarf planet formed out of cold material...
Pluto’s famous heart-shaped structure, named Tombaugh Regio, controls winds in the atmosphere of the dwarf planet and may give rise to features on its...
Many icy bodies in our Solar System have underground oceans. On the dwarf planet Pluto, an area called Sputnik Planitia suggests the presence of a subsurface...
The tenuous nitrogen atmosphere of the dwarf planet Pluto is predicted to ultimately collapse and freeze over.
This high-resolution image of Pluto was...
Collisions between bodies in our Solar System produce impact craters on large objects at a rate that depends on the population of impacting small bodies....
In 2006, the International Astronomical Union (IAU) established a definition of a planet that required it to clear its orbit, or in other words, be the...
Marking the anniversary of New Horizons’ historic flight through the Pluto system on July 14, 2015, NASA released high-resolution natural-color images...
