Hubble Sees Neptune's Mysterious Shrinking Storm

Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm -- once big enough to stretch across the Atlantic Ocean from Boston to Portugal -- is shrinking ... read more

Pluto's Hydrocarbon Haze Keeps Dwarf Planet Colder Than Expected

The gas composition of a planet's atmosphere generally determines how much heat gets trapped in the atmosphere. For the dwarf planet Pluto, however, the predicted temperature based on the ... read more

NASA Investigates Invisible Magnetic Bubbles in Outer Solar System

Forty years ago, the twin Voyagers spacecraft were launched to explore the frontiers of our solar system, and have since made countless discoveries, including finding magnetic bubbles around two of ... read more

Haumea, the Most Peculiar of Pluto Companions, Has a Ring Around It

The trans-neptunian belt contains four dwarf planets, among which Haumea stands out for its extremely elongated shape and rapid rotation. A stellar occultation makes it possible to establish the main ... read more

The Super-Earth That Came Home for Dinner

It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even ... read more

Brown Dwarf Weather Forecasts Improved

Dim objects called brown dwarfs, less massive than the Sun but more massive than Jupiter, have powerful winds and clouds -- specifically, hot patchy clouds made of iron droplets and silicate dust. ... read more

Neptune: Neutralizer-Free Plasma Propulsion

Plasma propulsion concepts are gridded-ion thrusters that accelerate and emit more positively charged particles than negatively charged ones. To enable the spacecraft to remain charge-neutral, a ... read more

Primitive Atmosphere Discovered Around 'Warm Neptune'

A pioneering new study uncovering the 'primitive atmosphere' surrounding a distant world could provide a pivotal breakthrough in the search to how planets form and develop in far-flung ... read more

Neptune's Journey During Early Planet Formation Was 'Smooth and Calm'

A major discovery has been made on the formation of icy bodies within the Kuiper Belt, unlocking unique evidence that Neptune's movement during early planet formation was a 'smooth and ... read more

Astronomers Discover Dark Past of Planet-Eating 'Death Star'

Scientists have made the rare discovery of a planetary system with a host star similar to Earth's sun. Especially intriguing is the star's unusual composition, which indicates it ingested ... read more

Microlensing Study Suggests Most Common Outer Planets Likely Neptune-Mass

A new statistical study of planets found by a technique called gravitational microlensing suggests that Neptune-mass worlds are likely the most common type of planet to form in the icy outer realms ... read more

Mystery Solved Behind Birth of Saturn’s Rings

A team of researchers has presented a new model for the origin of Saturn's rings based on results of computer simulations. The results of the simulations are also applicable to rings of other ... read more
