Nearly two years after its historic encounter with the dwarf planet Pluto, NASA's New Horizons spacecraft is getting ready for its next big adventure in the icy outskirts of the solar system.
Pluto, once considered the ninth and most distant planet from the sun, is now the largest known dwarf planet in the solar system. It is also one of the largest known members of the Kuiper Belt, a shadowy zone beyond the orbit of Neptune thought to be populated by hundreds of thousands of rocky, icy bodies each larger than 62 miles (100 kilometers) across, along with 1 trillion or more comets.
NASA's New Horizons team is hosting a live webcast today at 4 p.m. EST (2100 GMT) to discuss the historic Pluto flyby and tantalizing adventures that lie ahead.
NASA's New Horizons mission has revealed, for the first time, evidence of ice features known as "penitentes" beyond Earth.
Lacking a strong magnetic shield, Pluto's thin atmosphere is being eroded into space — but Charon is doing its bit to protect its dwarf planet buddy.
Pluto's strange "snakeskin" terrain is composed of ice ridges similar to, but much larger than, those found on Earth, a new study suggests.
The huge icy plain on Pluto known as Sputnik Planitia may not overlie an impact crater, as many researchers had assumed, a new study reports.
Pluto's famous heart-shaped feature made the dwarf planet roll over the eons, and this reorientation probably wouldn't have been possible without a subsurface ocean, new research suggests.
The rings of Saturn, Neptune and Uranus are composed of pieces of Pluto-like dwarf planets that strayed too close to the giant worlds long ago, a new study suggests.
The northwestern chamber of Pluto's "heart" has had its name changed from Sputnik Planum to Sputnik Planitia, to better reflect the characteristics of the region.
The last piece of New Horizons flyby data reached mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, early Tuesday morning (Oct. 25), NASA officials said.
On Pluto's moon Charon, scientists have found evidence of landslides. This is the first time this geologic feature has been discovered in the Kuiper Belt, according to New Horizons scientists.
More than a half dozen clouds may have been seen in Pluto's hazy atmosphere, researchers announced today (Oct. 18).
The tiny, faraway object that NASA's New Horizons spacecraft will fly by in 2019 is even redder than Pluto, new observations by the Hubble Space Telescope suggest.
A new face has been added to the solar system's family portrait: Scientists have discovered a new dwarf planet looping around the sun in the region beyond Pluto.
A new simulation of how Pluto got its "heart" reveals that the dwarf planet most likely has a deep ocean beneath its surface.
A pair of newfound planet-size objects may be the first binary worlds spotted outside our solar system, and their stellar neighbors might be pushing them ever closer.
