Scientists using NASA's Chandra X-ray Observatory have made the first detections of X-rays from Pluto. These observations offer new insight into the space environment surrounding the largest and best-known object in the solar system's outermost regions.

In June 2015, when the cameras on NASA's approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto's largest moon, Charon, mission scientists knew two things: they'd never seen anything like it elsewhere in our solar system, and they couldn't wait to get the story behind it. Over the past year, the scientists think they've solved the mystery.

Astronomers found signs of a growing planet around TW Hydra, a nearby young star, using the Atacama Large Millimeter/submillimeter Array (ALMA). Based on the distance from the central star and the distribution of tiny dust grains, the baby planet is thought to be an icy giant, similar to Uranus and Neptune in our Solar System. This result is another step towards understanding the origins of various types of planets.

For the first time, scientists have directly mapped Earth's fluctuating magnetic field and resulting electrical currents to aurora, thanks to northern lights observations from NASA's THEMIS mission.

Scientists have discovered that the depths of Uranus, Neptune and their satellites may contain extraordinary compounds, such as carbonic and orthocarbonic acids. It is no accident researchers have chosen these planets as a subject for their research. These gas giants consist mainly of hydrogen, carbon and oxygen, which are the three cornerstones of organic chemistry.

Research suggests that virtually all of Earth's life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to Mercury.

The solar system could be thrown into disaster when the sun dies if the mysterious 'Planet Nine' exists, according to new research.

In the race to discover a proposed ninth planet in our Solar System, researchers have observed several never-before-seen objects at extreme distances from the Sun in our Solar System.

Saturn, with its alluring rings and numerous moons, has long fascinated stargazers and scientists. After an initial flyby of Pioneer 11 in 1979, humanity got a second, much closer look at this complex planetary system in the early 1980s through the eyes of NASA's twin Voyager spacecraft.

Ancient hieroglyphic texts reveal Mayans made major discovery in math and astronomy, a researcher suggests. This study blends the study of Mayan hieroglyphics (epigraphy), archaeology and astronomy to present a new interpretation of the Venus Table, which tracks the observable phases of the second planet from the Sun.

Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to two billion years of its early history, according to NASA computer modeling of the planet's ancient climate.

New research finds that major volcanic activity on the planet Mercury most likely ended about 3.5 billion years ago. These findings add insight into the geological evolution of Mercury in particular, and what happens when rocky planets cool and contract in general.

Astronomers have discovered a new dwarf planet orbiting in the disk of small icy worlds beyond Neptune. The new object is about 700 km in diameter and has one of the largest orbits for a dwarf planet. Designated 2015 RR245 by the International Astronomical Union's Minor Planet Center, it was found using the Canada-France-Hawaii Telescope on Maunakea, Hawaii, as part of the ongoing Outer Solar System Origins Survey (OSSOS).

Scientists with NASA's Dawn mission have identified permanently shadowed regions on the dwarf planet Ceres where ice deposits could exist now.

Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras -- stunning light shows in a planet's atmosphere -- on the poles of the largest planet in the Solar System, Jupiter.

Astronomers have found an explanation for the chaotic behavior of the orbit of Halley's Comet.

Researchers have found that several volcanic deposits on Mercury's surface require mantle melting to have started close to the planet's core-mantle boundary, which lies only 400 km below the planets surface and making it unique in the solar system.

Scientists have discovered an elusive, dark moon orbiting Makemake, one of the 'big four' dwarf planets populating the Kuiper Belt region at the edge of our solar system.

Geologists trace Mercury's origins to weird, rare meteorite, and find planet cooled dramatically shortly after it formed.

An updated thermal model for Pluto suggests that a liquid water ocean beneath the dwarf planet's ice shell is a fairly likely scenario, and that the ocean is probably still there today.
