Explainer: Why Pluto Lost Planet Status As NASA Chief Urges Reconsideration
NASA Administrator Jared Isaacman has reignited the two-decade-old debate over Pluto's classification by publicly backing its reinstatement as a full planet, while NASA prepares scientific papers to challenge the International Astronomical Union's 20

White Dwarf Gobbles Up Nitrogen-Rich Ices of Pluto-Like World
Astronomers have observed a white dwarf, a highly compact stellar ember, that appears to have gobbled up an icy world akin to dwarf planet Pluto, a finding with implications regarding the likelihood of habitable planets beyond our solar system

NASA Data Shows Pluto’s Equator Is Lined with Towering Methane Ice Spires
New research based on New Horizons’ decade-old data has uncovered extensive bladed terrain made of methane ice on Pluto. These towering spires, arranged in spaced-out, parallel rows, are likely shaped by seasonal condensation and sublimation cycles. While the terrain spans over half the planet’s midsection, five times the width of continental U...

New Dwarf Planet Discovered Beyond Pluto, Hinting At Hidden 'Planet X'
The discovery of 2017 OF201 is significant, as it challenges the hypothesis of Planet Nine, a hypothetical planet thought to exist in the outer Solar System.

Dwarf Planet Ceres Once Hosted a Muddy Ocean Below Its Icy Surface
Recent research indicates that Ceres, the largest object in the asteroid belt, likely harboured a muddy ocean beneath its icy crust. Advanced computer simulations suggest that its surface features and gravity measurements point to a past rich in ice. With its proximity to Earth, Ceres presents a promising target for further exploration, making it t...

Scientists Discover An Unexpected Ring Around Dwarf Planet 'Quaoar'
Researchers discover a dwarf planet with a "impossible" ring and wonder how it could possibly exist.

First Giant Exoplanet Found Orbiting Extinguished Star
Astronomers have discovered a planet the size of Jupiter closely orbiting the smouldering remains of a dead star, the first time that an intact exoplanet has been discovered travelling around a white dwarf, according to research published Wednesday.

Ceres Dwarf Planet Is an ‘Ocean World’ With Salty Water Underground, NASA Data Suggest
Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an "ocean world" with a big reservoir of salty water under its frigid surface, scientists said in findings based on data obtained by NASA’s Dawn spacecraft.

Dwarf Planet Ceres An "Ocean World" In Astroid Belt Between Mars, Jupiter
Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an "ocean world" with a big reservoir of salty water under its frigid surface, scientists said in findings that raise interest in this dwarf planet as a possible outpost for life.

"Farout" Pink Dwarf Planet Is Solar System's Most Distant Object
Scientists have discovered the most distant object known in our solar system, so remote and unusual they chose the nickname "Farout" for the slow-moving, icy, pinkish dwarf planet about 120 to 130 times further from the sun than Earth.

New Distant Object With Orbit Found During Hunt For Planet X
In their search for unknown dwarf planets and Planet X and for distant Solar System objects, a team of scientists have discovered a new extremely distant object far beyond Pluto with an orbit.

New Dwarf Planet Spotted At The Very Fringe Of Solar System
A previously unknown dwarf planet circles through the far reaches of our solar system, the International Astronomical Union's Minor Planet Center announced Tuesday.

Pluto Gets A Buddy: A New Dwarf Planet Is Discovered In Our Solar System
Out beyond Neptune, past Pluto, through the chaos of the Kuiper belt to a point some 8.5 billion miles from the sun, a new dwarf planet has just joined our solar system.

Dwarf Planet Ceres May Hold A Towering Ice Volcano
Lots of folks may still be salty over Pluto's "demotion" from planet to dwarf planet, but it's becoming apparent that the little worlds with this designation are anything but boring. In a set of six studies published Thursday in Science, researchers report that Ceres - a dwarf planet in the asteroid belt between Mars and Jupiter - plays host to man...
