    Chalk up one more moon for Neptune. NASA announced the discovery of Neptune’s 14th moon Monday. The Hubble Space Telescope captured the moon as a white dot in photos of Neptune on the outskirts of our solar system. The new moon—Neptune’s tiniest at just 12 miles across—is designated S/2004 N 1. …

    PASADENA, Calif. – Scientists on the Cassini mission to Saturn are poring through hundreds of images returned from the Sept. 10 flyby of Saturn's two-toned moon Iapetus. Pictures returned late Tuesday and early Wednesday show the moon's yin and yang--a white hemisphere resembling snow, and the other as black as tar. Images show a surface that is heavily cratered, along with the mountain ridge that runs along the moon's equator. Many of the close-up observations focused on studying the strange 20-kilometer high (12 mile) mountain ridge that gives the moon a walnut-shaped appearance. "The images are really stunning," said Tilmann...

    The new moon could be related to Methone and Pallene A new moon has been discovered orbiting Saturn - bringing the planet's latest moon tally up to 60.The body was spotted in a series of images taken by cameras onboard the Cassini spacecraft. Initial calculations suggest the moon is about 2km-wide (1.2 miles) and its orbit sits between those of two other Saturnian moons, Methone and Pallene. The Cassini Imaging Team, who found the object, said Saturn's moon count could rise further still. New family The moon appears as a dim speck in images taken by the Cassini probe's...

    For the first time, astronomers have glimpsed one of Uranus's 27 moons passing in front of one of its siblings – a fleeting alignment that can reveal information about the moons, such as their mass, that cannot be gleaned in any other way. Researchers hope this will be the first in a bonanza of data returned from Uranus in the next year. That is because Uranus, which orbits the Sun every 84 years, is in an ideal geometry to view its moons. Such periods come around only once every 42 years, and the next will not occur until 2049.This series...

    The Cassini radar image (left) shows one of Titan's seas is larger than Lake Superior (right) Nasa's Cassini probe has found evidence for seas, probably filled with liquid hydrocarbons, at the high northern latitudes of Saturn's moon Titan.The dark features, detected by Cassini's radar, are much bigger than any lakes already detected on Titan. The largest is some 100,000 sq km (39,000 sq miles) - greater in extent than North America's Lake Superior. It covers a greater fraction of Titan than the proportion of Earth covered by the Black Sea. The Black Sea is the Earth's largest inland sea...

    What should follow the great success of Cassini-Huygens? The European and US space agencies are moving ahead on their next major missions to explore the Solar System. Nasa has begun choosing a destination for a "flagship" robotic venture along the lines of Cassini-Huygens, which has been exploring Saturn and its moons. It is considering four targets: the Jupiter system, Jupiter's moon Europa, and Saturn's moons Enceladus and Titan. The European Space Agency has called for proposals for one flagship mission and another medium-sized mission. Europa, Titan and Enceladus are also among the destinations expected to be proposed under the...

    June 5, 2006 | Evidence continues to mount that planets can form around very-low-mass objects. In fact, planets might even form around objects that are so low in mass that they themselves could be considered "planets." The latest results, reported at this week's American Astronomical Society meeting in Calgary, Alberta, come from groups led by Ray Jayawardhana (University of Toronto, Canada) and Subhanjoy Mohanty (Harvard-Smithsonian Center for Astrophysics).

    Tiny, red-tinted Amalthea is only about 270 kilometres (168 miles) in length and half that in width. Its mass, estimated from its gravitational effect on Galileo when the spacecraft passed within about 160 kilometres (99 miles) of the moon on 5 November, is far smaller than had been predicted. Amalthea's overall density is close to the density of water ice, Dr Anderson says. But the moon is almost certainly not a solid hunk of ice... Dr Johnson adds: "This finding supports the idea that the inner moons of Jupiter have undergone intense bombardment and break-up. Amalthea may have formed originally...

    Hubble discovers new rings and moons around Uranus Washington: NASA's Hubble Space Telescope has discovered a new pair of rings around Uranus and two new small satellites orbiting the planet. The rings are very far away from the planet and the largest of them is twice the diameter of the planet's previously known rings. Astronomers are now calling them Uranus' second ring system. Also one of the new moons shares its orbit with one of the rings. The findings are to be published in the journal Science. Dr. Jennifer Wiseman, program scientist for Hubble at NASA Headquarters said that analysis...

    BALTIMORE - Pluto has three moons, not one, new images from the Hubble Space Telescope suggest. Pluto, discovered as the ninth planet in 1930, was thought to be alone until its moon Charon was spotted in 1978. The new moons, more than twice as far away as Charon and many times fainter, were spotted by Hubble in May. While the observations have to be confirmed, members of the team that discovered the satellites said Monday they felt confident about their data. "Pluto and Charon are not alone, they have two neighbors," said Hal Weaver of the Johns Hopkins University Applied...

    Astronomers have discovered 12 new moons orbiting Saturn, bringing its number of natural satellites to 46.The moons are small, irregular bodies - probably only about 3-7km in size - that are far from Saturn and take about two years to complete one orbit. All but one circles Saturn in the opposite direction to its larger moons - a characteristic of captured bodies. Jupiter is the planet with the most moons, 63 at the last count. Saturn now has 46. Uranus has 27 and Neptune 13. The latest ones were found last year using the Subaru telescope in Hawaii. Confirmation...

    PASADENA, Calif. (AP) - Northrop Grumman Space Technology has been selected to help NASA design a nuclear-powered spacecraft to orbit and explore three moons of Jupiter that may have oceans beneath their icy surfaces. The $400 million contract with the Redondo Beach, Calif.-based unit of Northrop Grumman covers work through mid-2008, NASA's Jet Propulsion Laboratory said Monday. The Prometheus Jupiter Icy Moons Orbiter spacecraft will be designed to explore Callisto, Ganymede and Europa sometime in the next decade, after launching in 2012 or later. Scientists want to know what the big moons are made of, their history and whether the...

    TINY MOONS DISCOVERED AT URANUS Astronomers using NASAs Hubble Space Telescope discovered two of the smallest moons yet found orbiting Uranus, NASA announced. The two moons, each about 12 to 16 kilometers in diameter, are so faint they were not detected by the Voyager 2 spacecraft, which discovered 10 small moons when it flew by Uranus in 1986. Uranus now has 24 known moons. Astronomers hope to learn more about the orbits of the moons and their interaction with other Uranus moons with further Hubble observations. They also want to understand what role the newly discovered moons may play in...

By Dr David Whitehouse BBC News Online science editor Astronomers have discovered the only known lunar crater to have been formed in recorded history. In 1953 a flash was seen on the Moon that was taken to be the impact of a small asteroid. But ground-based telescopes were not powerful enough to see any crater. But now, searching more detailed images of the Moon obtained by orbiting spacecraft, researchers have found a small, fresh, crater in the same position as the flash....
