With input from more than 2,000 members of the public, team members on NASA's Cassini mission to Saturn have chosen a name for the final phase of the mission: the Cassini Grand Finale.
In just over a year, the New Horizons spacecraft will fly past Pluto, giving us our first detailed look at the dwarf planet.
June 30 marks the 10th anniversary of the Cassini spacecraft’s arrival in the Saturn system, beginning a four-year primary mission that was extended on three occasions and ultimately led to the collection of more than 500 GB of data and the publication of well over 3,000 scientific papers.
A joint research effort between NASA and the European Space Agency has found proof that nitrogen within the atmosphere of Saturn's moon Titan came from conditions very similar to those that formed most of the ancient comets in the Oort cloud.
A mysterious “island” that suddenly appeared and then disappeared on one of Saturn’s moons, as seen in NASA images, has scientists baffled.
Patent recognizes IO's distinct research and development of software-defined data centers PHOENIX, June 19, 2014 /PRNewswire/ -- IO, a
Astronauts looking to lay the groundwork for a future settlement on the Moon may want to save some time by not looking for water on the side of the Moon that is always exposed to the Sun.
NASA scientists have created a new recipe that captures key flavors of the brownish-orange atmosphere around Saturn’s largest moon, Titan.
If there are cracks on the ice-covered surface of Charon, an upcoming analysis of those fractures could help determine whether or not the interior of Pluto’s moon was warm enough to have been home to a subterranean ocean of liquid water.
Despite being the nearest astronomical object to Earth, and the only extraterrestrial site of human visitors, the Moon still contains mysteries that have puzzled scientists for the better part of a century. Perhaps the greatest question surrounding lunar history is its two-faced nature.
Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...
Saturn's moon Hyperion -- Hyperion is a moon of Saturn discovered by Bond and Lassell in 1848. It is the largest highly irregular (non-spherical) body in the solar system (Proteus is quite a bit larger but is almost spherical). It seems likely that Hyperion is a fragment of a larger body that was broken by a large impact in the distant past. The largest crater on its surface is approximately 120 kilometers in diameter and 10 kilometers deep. Like most of Saturn's moons, Hyperion's low...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
Jupiter's Moon Europa -- Europa is a puzzle. The sixth largest moon in our Solar System, Europa confounds and intrigues scientists. Few bodies in the Solar System have attracted as much scientific attention as this moon of Jupiter because of its possible subsurface ocean of water. The more we learn about this icy moon, the more questions we have. Because the nature of science is to ask questions, we cannot resist the mystery of Europa and its potential for possessing an ocean. Early...

- The state or condition of numbness of a part due to pressure on a nerve: as, the obdormition of a limb.
