Samples of icy spray shooting from Saturn's moon Enceladus collected during Cassini spacecraft flybys show the strongest evidence yet for the existence of a large-scale, subterranean saltwater ocean, says a new international study led by the University of Heidelberg and involving the University of Colorado Boulder. The new discovery was made during the Cassini-Huygens mission to Saturn, a collaboration of NASA, the European Space Agency and the Italian Space Agency. Launched in 1997, the mission spacecraft arrived at the Saturn system in 2004 and has been touring the giant ringed planet and its vast moon system ever since. The plumes...

WASHINGTON (AFP) – A pair of NASA probes wandering in deep space discovered that the outer edge of the solar system contains curious magnetic bubbles and is not smooth as previously thought, astronomers said Thursday. The NASA Voyager twin spacecraft, which launched in 1977, are currently exploring the furthest outlays of the heliosphere, where solar wind is slowed and warped by pressure from other forces in the galaxy, the US space agency said. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt," said astronomer Merav Opher of Boston University. "Far, far away...

A hundred million years ago, a triple-star system was traveling through the bustling center of our Milky Way galaxy when it made a life-changing misstep. The trio wandered too close to the galaxy's giant black hole, which captured one of the stars and hurled the other two out of the Milky Way. Adding to the stellar game of musical chairs, the two outbound stars merged to form a super-hot, blue star. This story may seem like science fiction, but astronomers using NASA's Hubble Space Telescope say it is the most likely scenario for a so-called hypervelocity star, known as HE...

Astronomers have confirmed the first discovery of an alien planet in our Milky Way that came from another galaxy, they announced today (Nov. 18). The Jupiter-like planet orbits a star that was born in another galaxy and later captured by our own Milky Way sometime between 6 billion and 9 billion years ago, researchers said. A side effect of the galactic cannibalism brought a faraway planet within astronomers' reach for the first time ever. [Illustration of the extragalactic planet] "This is very exciting," said study co-author Rainer Klement of the Max-Planck-Institut fur Astronomie (MPIA) in Heidelberg, Germany. "We have no...

- NASA Announces Televised Chandra News Conference - NASA will hold a news conference at 12:30 p.m. EST on Monday, Nov. 15, to discuss the Chandra X-ray Observatory's discovery of an exceptional object in our cosmic neighborhood.

PARIS (AFP) – The Solar System could be nearly two million years older than thought, according to a study published on Sunday by the journal Nature Geoscience. The evidence comes from a 1.49-kilo (3.2-pound) meteorite, found in the Moroccan desert in 2004, that contains a "relict" mineral, which is one of the oldest solid materials formed after the birth of the Sun. ... As a result, the Solar System is likely to be between 300,000 and 1.9 million years older than previous estimates, ..

Jupiter, the biggest planet in the solar system, might have gained its dominant position after swallowing up a smaller planet, scientists believe. Studies on Jupiter have revealed that the giant planet, which is more than 120 times bigger than the Earth, has an extremely small core that weighs just two to 10 Earth masses. Now scientists have claimed that Jupiter's core might have been vaporised in huge collision with a planet up to ten times the size of Earth, the New Scientist reported. Researchers led by by Shu Lin Li of Peking University in China have modelled what might have...

Is the Sun going to enter a million-degree galactic cloud of interstellar gas soon? Scientists from the Space Research Centre of the Polish Academy of Sciences, Los Alamos National Laboratory, Southwest Research Institute, and Boston University suggest that the ribbon of enhanced emissions of energetic neutral atoms, discovered last year by the NASA Small Explorer satellite IBEX, could be explained by a geometric effect coming up because of the approach of the Sun to the boundary between the Local Cloud of interstellar gas and another cloud of a very hot gas called the Local Bubble. If this hypothesis is correct,...

The solar system is passing through an interstellar cloud that physics says should not exist. In the Dec. 24th issue of Nature, a team of scientists reveal how NASA's Voyager spacecraft have solved the mystery. "Using data from Voyager, we have discovered a strong magnetic field just outside the solar system," explains lead author Merav Opher, a NASA Heliophysics Guest Investigator from George Mason University. "This magnetic field holds the interstellar cloud together and solves the long-standing puzzle of how it can exist at all." The discovery has implications for the future when the solar system will eventually bump...

Jupiter has lost one of its iconic red stripes and scientists are baffled as to why. The largest planet in our solar system is usually dominated by two dark bands in its atmosphere, with one in the northern hemisphere and one in the southern hemisphere. However, the most recent images taken by amateur astronomers have revealed the lower stripe known as the Southern Equatorial Belt has disappeared leaving the southern half of the planet looking unusually bare. The band was present in at the end of last year before Jupiter ducked behind the Sun on its orbit. However, when it...

Al Gore has a new argument for why carbon dioxide is the global warming boogeyman -- and it’s simply out of this world. Testifying before the Senate Foreign Relations Committee on Wednesday with yet another one of his infamous slide shows, Gore observed that the carbon dioxide (CO2) in Venus’ atmosphere supercharges the second-planet-from-the-sun’s greenhouse effect, resulting in surface temperatures of about 870 degrees Fahrenheit. Gore added that it’s not Venus’ proximity to the Sun that makes the planet much warmer than the Earth, because Mercury, which is even closer to the Sun, is cooler than Venus. Based on this...

WASHINGTON (AFP) – Pluto, the dwarf planet on the outer edge of our solar system, has a dramatically ruddier hue than it did just a few years ago, NASA scientists said Thursday, after examining photos taken by the Hubble Space Telescope. They said the distant orb appears mottled and molasses-colored in recent pictures, with a markedly redder tone that most likely is the result of surface ice melting on Pluto's sunlit pole and then refreezing on the other pole. The remarkable color shift, which apparently took place between 2000 and 2002, confirms that Pluto is a dynamic world undergoing dramatic...

A photo from Cassini shows sunlight reflecting from a giant lake of methane on the northern half of Saturn's moon Titan. (CNN) -- NASA scientists revealed Friday a first-of-its-kind image from space showing reflecting sunlight from a lake on Saturn's largest moon, Titan. It's the first visual "smoking gun" evidence of liquid on the northern hemisphere of the moon, scientists said, and the first-ever photo from another world showing a "specular reflection" -- which is reflection from a liquid surface. Jaumann said he was surprised when he first saw the photos transmitting from Cassini, orbiting Saturn about a billion...

NASA scientists have discovered a mysterious ribbon around our solar system —- a stripe made of hydrogen —- that defies all current expectations about what the edge of the solar system might look like. Richard Fisher, the director of NASA's Heliophysics Division, tells NPR's Guy Raz that this discovery is a big moment for the scientific community. "We thought we knew everything about everything, and it turned out that there were unknown unknowns."

Oct 7, 2009 — Saturn has a newly-discovered ring to add to its decor – the largest of all. It’s so big, it makes Saturn look like a speck in the middle of it. The ring, located at the orbit of the small outer moon Phoebe, is inclined 27 degrees and revolves backwards around Saturn. This was announced today by...

Aluminium is the most abundant metal in the Earth's crust and is used to make bikes, cars and food cans. Now, thanks to research conducted at the University of Nancy, France, the metal may also be able to shed light on the processes that occurred during the formation of the solar system.Models of the evolution of the early solar system rely on knowing the precise times at which the oldest particles in the solar system formed. Some of the oldest particles clumped together to form chondrites - primitive meteorites - and these grain-like building blocks are known as calcium-aluminium rich...

French and Italian scientists have analysed a meteorite and discovered that it contains a unique and primordial rock fragment that is thought to have remained largely unaltered since the solar system formed around 4.6 billion years ago. The scientists believe the xenolith, which shows unprecedented isotopic variations of nitrogen, may offer insight into the solar system's formation and say it poses serious problems for current models of light element isotopic fractionation.  Light element isotopic ratios are the result of formation mechanisms and particular physical and chemical conditions. Understanding them can therefore help determine whether extraterrestrial materials formed in the solar nebula...

Solar System Secrets Solved by Brian Thomas, M.S.* A recent issue of New Scientist contained a series of articles that explored “The Six Biggest Mysteries of Our Solar System.” One article posed the question, “How was the solar system built?”1 “Built” is a good word, considering the solar system contains an array of features that appear precisely orchestrated. For example, if all the planets, as well as the sun, came from the same dust cloud—as the Nebular Hypothesis claims—then why does each planet have an entirely unique composition? Why do the planets’ collective orbital velocities, trajectories, and distances combine to...

<p>Conveyor of a super-Einsteinian theory of gravitation that explains, among many other post-Einstein-effects, the Sun-Earth-Connection and the true cause of the global climate changes.</p> <p>As the glaciological and tree ring evidence shows, climate change is a natural phenomenon that has occurred many times in the past, both with the magnitude as well as with the time rate of temperature change that have occurred in the recent decades. The following facts prove that the recent global warming is not man-made but is a natural phenomenon.</p>

A "twin" of our solar system has been discovered by an international team of scientists that includes astronomers from Tel Aviv University. Its report on the revelation appeared in Thursday's issue of the prestigious Science journal. The newly discovered planets and the sun around which they revolve are very different from the 10 other solar systems discovered during the past decade. However, the new solar system is significantly similar to our solar system, especially in regard to the planets‚ relative weights and distances between them. Most of the 10 other systems were discovered by measuring the "wobbly paths" of their...
