Superionic ice is strangely different, and yet it may be among the most abundant forms of water in the Universe – presumed to fill not only the interiors of Uranus, Neptune, but also similar exoplanets.
Researchers were caught by surprise when they observed what they believe to be the aftermath of two giant planets colliding.
A distant lump of space rock may have a surprising amount in common with the core of our own planet.
Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth by NASA show evidence of high-carbon content and water.
The densest naturally occurring element on the periodic table is the metal osmium. But there are some objects out there in the Solar System that seem to be way more dense than osmium.
A new method for scanning telescope images for the faintest signs of rock far beyond Pluto has uncovered evidence that our Solar System's disc of material extends far further into interstellar space than we thought.
Researchers note a "synchronicity" of geochemical signals suggesting that fragments of a comet struck Earth approximately 13,000 years ago.
Among the most striking geologic features on the surface of Arrokoth is the ensemble of large, broadly similarly sized mound-like features seen on the larger lobe.
A very rare, strange burst of extraordinarily bright light in the universe just got even stranger. The phenomenon, called a Luminous Fast Blue Optical Transient (LFBOT), flashed onto the scene where it wasn't expected to be found.
Sunlight on Mars interacts with iron-rich dust that hangs in the atmosphere. This ultimately scatters lower-frequency red light through the sky during the day. At twilight, however, the red light is filtered away and the sky glows a cool blue.
Resent studies question the evolution of the Moon magnetic field thanks to its demonstration of the existence of the inner core.
in the Trapezium cluster, scientists have found dozens of planet-like objects roughly the mass of Jupiter untethered to any star, drifting through the galaxy in gravitationally-bound pairs.
Solving the mystery of how planets like Earth were formed is an important question for understanding the origin of life.
A Spanish company launched the country's first private rocket on Saturday in a step towards bringing Spain into the exclusive club of space-faring nations.
The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light.
