Scientists have identified a new dwarf planet in our Solar System, and it's lurking way out in the edges, some 13.6 billion km from the Sun.
NASA's Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter. Out of ten observations, Hubble saw what may be water vapor plumes on three of the images.
A prior study demonstrated that Pluto's center is sufficiently warm to bolster a fluid water sea, and now we've discovered that it may be immense - no less than 100 km (62 miles) profound.
A new study proves that the Earth and other planetary objects formed in the early years of the Solar System share similar chemical origins – a finding at odds with accepted wisdom held by scientists for decades.
Scientists believe Venus was once Earth-like. How is this possible and what caused the planet to turn toxic?
Research by Rice University Earth scientists 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.
NASA's Juno spacecraft has sent back the first-ever images of Jupiter's north pole, taken during the spacecraft's first flyby of the planet with its instruments switched on.
Earlier in its history, the second planet from the sun may have had a liquid water ocean and temperatures suitable for life, a new study shows.
Saturn's exotic moon Titan, with its thick atmosphere and large, methane lakes, continues to beguile planetary scientists. Now, using data collected by an altimeter aboard NASA's Cassini spacecraft, scientists have found liquid methane flowing through deep gorges on the moon's surface.
Using the Pan-STARRS telescope in Hawaii, astronomers detected a mysterious trans-Neptunian object (TNO) moving backwards around the sun.
The new data indicates that while Ceres, which is the largest body in the asteroid belt, was once warm enough for water to have shifted internally, those temperatures were never high enough for an iron core to separate from the rest of the dwarf planet's interior.
Mineral veins found in Mars's Gale Crater were formed by the evaporation of ancient Martian lakes, a new study has shown.
A NASA news release describes a recently published study which has found that Jupiter’s Great Red Spot appears to act as a heat source and is likely the reason behind the planet’s surprisingly high upper atmospheric temperatures.
Icy world 2015 RR245 has been classified a dwarf planet by the International Astronomical Union's Minor Planet Center. It was found using the Canada-France-Hawaii Telescope on Maunakea, Hawaii.
Scientists have uncovered a chemical trail that suggests prebiotic conditions may exist on Saturn's largest moon Titan. This moon features terrain with Earthlike attributes.
