  • Mysterious Energy Ribbon at Solar System's Edge a 'Cosmic Roadmap'

    02/13/2014 9:00:18 PM PST · by 12th_Monkey · 51 replies ^ | February 13, 2014 | Elizabeth Howell
    A strange ribbon of energy and particles at the edge of the solar system first spotted by a NASA spacecraft appears to serve as a sort of "roadmap in the sky" for the interstellar magnetic field, scientists say. By comparing ground-based studies and in-space observations of solar system's mysterious energy ribbon, which was first discovered by NASA's Interstellar Boundary Explorer (IBEX) in 2009, scientists are learning more details about the conditions at the solar system's edge. The study also sheds light into the sun's environment protects the solar system from high-energy cosmic rays. The ribbon is roughly perpendicular to the...

    When a person thinks about light, usually the first thing that will come to mind is the sun. We have been taught that the sun is the center of the solar system and thus it is the light of the world. This ball of fire that life on earth depends upon, is so massive in size that it contains 99.85% of all the matter in the Solar System, or 332,800 times that of earth. The distance from earth to the sun is 93,000,000 miles, which would take you 71 years to travel going 150 mph. The sun creates energy...

    Our solar system is four and a half billion years old, but its formation may have occurred over a shorter period of time than we previously thought, says an international team of researchers from the Hebrew University of Jerusalem and universities and laboratories in the US and Japan. Establishing chronologies of past events or determining ages of objects require having clocks that tick at different paces, according to how far back one looks. Nuclear clocks, used for dating, are based on the rate of decay of an atomic nucleus expressed by a half-life, the time it takes for half of...

    For the first time, scientists have captured images of auroras above the giant ice planet Uranus, finding further evidence of just how peculiar a world that distant planet is. Detected by means of carefully scheduled observations from the Hubble Space Telescope, the newly witnessed Uranian light show consisted of short-lived, faint, glowing dots – a world of difference from the colorful curtains of light that often ring Earth's poles. In the new observations, which are the first to glimpse the Uranian aurora with an Earth-based telescope, the researchers detected the luminous spots twice on the dayside of Uranus – the...

    Jupiter might be having a change of heart. Literally. New simulations suggest that Jupiter's rocky core has been liquefying, melting, and mixing with the rest of the planet's innards. With this new data, astronomers hope to better explain a recent puzzling discovery of a strange planet outside of our solar system. "It's a really important piece of the puzzle of trying to figure out what's going on inside giant planets," said Jonathan Fortney, a planetary scientist at the University of California Santa Cruz who was not affiliated with the research. Conventional planetary formation theory has modeled Jupiter as a set...

    Life as we know it exists on a cozy planet in a stable orbit around a sun shining brightly in its sky. But a new study hints that the most common life in the universe might exist deep inside eternal-night worlds far from any star, adrift in the icy dark of interstellar space. Researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University estimate that "nomad" planets, ejected from their home stellar system and now free-floating through the Milky Way, could outnumber stars by as many as 100,000 to 1.

    With all the attention that astronomers have lavished on old Sol over the centuries, you'd think that by now they'd know its diameter to, oh, 10 or 12 significant digits. During the past 40 years, astronomers have attempted to measure the Sun's sizedozens of times using various methods. The dashed line corresponds to a radius of 696,000 km, the value most often used. While the Sun's girth has indeed been measured dozens of times over the past 40 years, the results haven't converged on a single value and scatter by as much as ± 0.1%. One big reason is that,...

    Lakes on Saturn’s moon Titan don’t do the wave very well. Radar images from NASA’s Cassini spacecraft show glassy smooth surfaces, even on bodies like Ligeia Mare, a large sea roughly 400 kilometers (250 miles) wide. There are patterns on the shoreline of the southern hemisphere's Ontario Lacus that might be from waves, but the features aren’t definitive. Winds haven’t been too high on Titan since Cassini first arrived in Saturn's system in 2004, so the lack of waves is odd but understandable. The ESA’s Huygens probe sent back amazing surface images, including snapshots of delta-looking features, when it made...

    Most stars are born in clusters rather than singly, and there’s plenty of evidence that the Sun was too. For one thing, the material of the infant solar system (as preserved in the earliest meteorites) was enriched by fresh supernova debris from at least one very young, massive star (having 15 to 25 solar masses) that exploded less than 5 light-years away, no more than 2 million years after the Sun's formation. Today no such massive star exists within 300 light-years of the Sun. Clearly, the early solar system had stars close around it. But that was 4.57 billion years...

    When squeezed to pressures and temperatures like those inside giant planets, water molecules are less squeezable than anticipated, defying a set of decades-old equations used to describe watery behavior over a range of conditions. Studying how molecules behave in such environments will help scientists better understand the formation and composition of ice giants like Uranus and Neptune, as well as those being spotted in swarms by planet hunters. The new work, which appears in the March 2 Physical Review Letters, also suggests that textbooks about planetary interiors and magnetic fields may need reworking. “At this point, it’s worth putting together...

By European Planetary Science Congress, AAS Division for Planetary Science — Uranus’ highly tilted axis makes it something of an oddball in our solar system. The accepted wisdom is that Uranus was knocked on its side by a single large impact, but new research rewrites our theories of how Uranus became so tilted and also solves fresh mysteries about the position and...

    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...

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...

    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...

    PARIS (AFP) - Astronomers on Wednesday announced they had spotted the first planet beyond the Solar System that has water, the precious ingredient for life. The watery world, though, is far beyond the reach of our puny chemically-powered rockets -- and in any case is quite uninhabitable. It is made of gas rather than rock and its atmosphere reaches temperatures hot enough to melt steel, which means the water exists only as superheated steam. The find, named HD189733b, is about 15 percent bigger than our Jupiter and orbits a star in the constellation of Vulpecula the Fox, according to a...

    Sometimes the line to get into the Imax theater at the American Museum of Natural History seems long enough to stretch all the way out to other planets. Now it does. This weekend “Beyond,” a one-year exhibition of more than 30 large-format photographs of Earth’s planetary neighbors, opens in the museum’s Imax Gallery, a corridor by the theater that is also a pathway to the Rose Center for Earth and Space. Michael Benson, a writer, photographer and filmmaker, created the stunning series of pictures from the enormous archives of images taken over the years by robotic explorers of the solar...

    Mars is unlikely to sport beachfront property any time soon, but the planet has enough water ice at its south pole to blanket the entire planet in more than 30 feet of water if everything thawed out. With a radar technique, astronomers have penetrated for the first time about 2.5 miles (nearly four kilometers) beneath the south pole's frozen surface. The data showed that nearly pure water ice lies beneath. • Click here to visit's Space Center. Discovered in the early 1970s, layered deposits of ice and dust cap the north and south poles of Mars. Until now, the...

    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...
  • White Dwarf Hints at Our Solar System's End (G29-38)

    A debris disk spied recently around a distant dead star is likely the remains of an asteroid that was vaporized when the star died, scientists say. The discovery, detailed in the Dec. 22 issue of the journal Science, could be a sign of what will happen in our own solar system in a few billion years. Because the crushed asteroid was probably gravitationally lassoed in by one or more planets, the finding also provides evidence that planetary systems can form around massive stars. While analyzing the light spectra of several hundred white dwarfs, astronomer Boris Gänsicke of the University of...

    Stargazers will get a rare triple planetary treat this weekend with Jupiter, Mercury and Mars appearing to nestle together in the predawn skies. About 45 minutes before dawn on Sunday those three planets will be so close that the average person's thumb can obscure all three from view. They will be almost as close together on Saturday and Monday, but Sunday they will be within one degree of each other in the sky. Three planets haven't been that close since 1925, said Miami Space Transit Planetarium director Jack Horkheimer. And it won't happen again until 2053, he said. "Jupiter will...

    Astronomers have discovered two new planets outside our solar system, both extremely close to their stars and thus among the hottest ever found. A University of Florida astronomer is among more than three dozen astronomers who found the new large planets, announced today at the Transiting Extrasolar Planets Workshop at the Max Planck Institute for Astronomy in Heidelberg, Germany. Stephen Kane, a UF postdoctoral associate, said he and his colleagues pinpointed the planets by detecting the slight dimming of starlight that occurs when the planets pass in front of their stars. Of about 200 planets discovered so far, the new...

    Sept. 21, 2006: Almost every day, the great antennas of NASA's Deep Space Network turn to a blank patch of sky in the constellation Ophiuchus. Pointing at nothing, or so it seems, they invariably pick up a signal, faint but full of intelligence. The source is beyond Neptune, beyond Pluto, on the verge of the stars themselves. It's Voyager 1. The spacecraft left Earth in 1977 on a mission to visit Jupiter and Saturn. Almost 30 years later, with the gas giants long ago seen and done, Voyager 1 is still going and encountering some strange things....
