  • Astronomy Picture of the Day -- No X-rays from SN 2014J

    NASA ^ | August 16, 2014 | (see photo credit)
    Explanation: Last January, telescopes in observatories around planet Earth were eagerly used to watch the rise of SN 2014J, a bright supernova in nearby galaxy M82. Still, the most important observations may have been from orbit where the Chandra X-ray Observatory saw nothing. Identified as a Type Ia supernova, the explosion of SN2014J was thought to be triggered by the buildup of mass on a white dwarf star steadily accreting material from a companion star. That model predicts X-rays would be generated when the supernova blastwave struck the material left surrounding the white dwarf. But no X-rays were seen from...
  • NASA finds mysterious signal that baffles astronomers

    NASA's Chandra X-ray observatory has found a mysterious X-ray signal that astronomers are speculating could signal the presence of dark matter some 240 million light years away from Earth. A leading theory, NASA reports, is that the X-rays are a result of decaying "sterile neutrinos," which are particles that could potentially produce dark matter. Astronomers believe dark matter accounts for 85 percent of all matter in the universe, but dark matter does not emit or absorb light as does the "normal" matter in planets, stars, and galaxies, so its detection is much more difficult. NASA notes that normal matter may...

    Conservatives in the Ohio House this week blocked a move widely viewed as an attempt by Governor John Kasich to set aside money he could later spend on Medicaid expansion without legislative approval. The version of House Bill 483 (HB 483) passed by the Ohio Senate included a last-minute change to move as much as $300 million in surplus state revenue to the state Medicaid Reserve Fund. Legislators feared this was an effort by the Kasich Administration to circumvent the General Assembly for spending on the Obamacare Medicaid expansion when an existing appropriation expires in mid-2015. ...

    The November 2010 testimony of Morales helped convict Ingmar Guandique, the man charged with killing Levy in Washington, D.C.’s Rock Creek Park in May 2001. Levy’s death occurred shortly before she was to return to her family’s Modesto, Calif., home, and her disappearance drew national attention following speculation and then revelations that she had been having an affair with then-Rep. Gary Condit. A former cellmate of Guandique, Morales testified that the younger inmate had confessed to him that he had killed Levy. Guandique was sentenced to 60 years following his conviction in 2010 on first-degree murder charges Guandique’s defense attorneys,...

    WASHINGTON -- A judge has been holding secret hearings in the case of the man convicted in the 2001 killing of Chandra Levy, the latest twist in a high-profile murder that went unsolved for years and captivated the public because of the intern's romantic relationship with a California congressman. The meetings, held sporadically behind closed doors at the courthouse over the last several weeks, raise questions about what comes next in a criminal case that appeared resolved by the 2010 conviction of Ingmar Guandique. The illegal immigrant from El Salvador is now serving a 60-year prison sentence in Levy's death,...

About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way Galaxy. M101 was also one of the original spiral nebulae observed with Lord Rosse's large 19th century telescope, the Leviathan of Parsontown. In contrast, this mulitwavelength view of the large island universe is a composite of images recorded by space-based telescopes in the 21st century.

    Astronomers have found strong evidence that a massive black hole is being ejected from its host galaxy at a speed of several million miles per hour. New observations from NASA's Chandra X-ray Observatory suggest that the black hole collided and merged with another black hole and received a powerful recoil kick from gravitational wave radiation. "It's hard to believe that a supermassive black hole weighing millions of times the mass of the sun could be moved at all, let alone kicked out of a galaxy at enormous speed," said Francesca Civano of the Harvard-Smithsonian Center for Astrophysics (CfA), who led...

    Astronomers have used NASA's Chandra X-ray Observatory to discover the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. At a distance of 160 million light years, it is also the nearest known pair of supermassive black holes. The black holes are located near the center of the spiral galaxy NGC 3393. Separated by only 490 light years, the black holes are likely the remnant of a merger of two galaxies of unequal mass a billion or more years ago. "If this galaxy wasn't so close we'd have no chance of separating the two...

    Popular Science ^ | February 24, 2011 | Clay Dillow
    Superfluids are strange states of matter, typically forming at very low and very high temperatures, exhibiting gonzo properties like a seemingly gravity-defying tendency to climb up the walls of containers and friction-free superconductivity. That is, they are perfect conductors that don't lose energy during transmission. And the fact that they appear to exist at the center of neutron stars tells scientists a lot about nuclear interactions in high-density matter and the life-cycles of neutron stars. The pressure within neutron stars is so intense that in the stars' cores, charged particles merge, resulting in a star mostly consisting of neutrons (hence...

At an April 10 briefing at NASA headquarters in Washington, D.C., researchers argued that observations by the orbiting Chandra X-Ray Observatory indicate that the astronomical object dubbed RXJ1856.5-3754 may lack the neutrons, protons, and electrons of ordinary matter. Another object, 3C58, may contain odd forms of matter surrounded by neutrons. Since its discovery in 1996, astronomers had thought that RXJ1856...

    WASHINGTON – The man convicted of killing Washington intern Chandra Levy nearly a decade ago was sentenced Friday to 60 years in prison. In November, a jury convicted Ingmar Guandique of first-degree murder in Levy's 2001 disappearance and death, despite a lack of witnesses and no DNA evidence linking him to the crime. Levy's mother, Susan Levy, asked Guandique directly if he had been responsible for her daughter's death. He shook his head. "Mr. Guandique, you are lower than a cockroach," Susan Levy told Guandique, before closing her statement with: "F... you." Guandique, wearing an orange prison jumpsuit, told the...

    DEVELOPING: A jury has reached a verdict in the trial of a man accused of killing Washington intern Chandra Levy, MyFoxDC.com reports. Ingmar Guandique is charged with murder in Levy's death nearly a decade ago. Levy disappeared in 2001. Her case drew attention when she was romantically linked to then-Congressman Gary Condit. The California Democrat was initially a suspect but police no longer think he was involved. Prosecutors say Levy's death fits a pattern of attacks by Guandique in 2001 in Washington's Rock Creek Park. That's where her remains were found.

    Like gluttonous piranhas, supermassive black holes in young galaxy clusters gorge on bountiful gas until little fuel is left, and then they fade away, a new study suggests.Using NASA's Chandra X-ray Observatory, astronomers tallied the number of rapidly growing supermassive black holes, called active galactic nuclei, or AGN, in two populations of galaxy clusters. One group consisted of young-looking clusters located very far from Earth, and the other consisted of an older group located closer to us. The results of the survey, detailed in the July 20 issue of The Astrophysical Journal Letters, showed that the more distant, younger clusters...

    You would think that in the midst of the liberal media's fight to rip Arizona's Immigration Law, that the phrase ‘illegal immigrant' would be fairly easy to use in an appropriate manner. Yet that is seemingly only the case when the phrase is used to cast common-sense immigration enforcement as discriminatory. But when it comes to a story that could shed light on why enforcement is a necessity for the safety and security of a nation and its people, then the phrase - no matter how accurate - is quickly forgotten.

    Astronomers have found a black hole where few thought they could ever exist, inside a globular star cluster. The finding has broad implications for the dynamics of stars clusters and also for the existence of a still-speculative new class of black holes called 'intermediate-mass' black holes. The discovery is reported in the current issue of Nature. Tom Maccarone of the University of Southampton in England leads an international team on the finding, made primarily with the European Space Agency's XMM-Newton satellite. Globular clusters are dense bundles of thousands to millions of old stars, and many scientists have doubted that black...

    Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. "This is the most energetic cosmic event, besides the Big Bang, which we know about," said team member Maxim Markevitch of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. These observations provide the strongest evidence yet that most of the matter in the universe is dark. Despite considerable evidence for dark matter, some scientists have proposed alternative theories for gravity where it...

    WASHINGTON - With gasoline hitting $3 per gallon, scientists have just found the most energy-efficient engines in the universe — black holes, those whirling super-dense centers of galaxies that suck in nearly everything. The jets of energy spurting out of older ultra-efficient black holes also seem to be playing a crucial role as zoning cops in large galaxies, preventing too many stars from sprouting. That explains why there aren't as many burgeoning galaxies chock full of stars as previously expected, said scientists citing results from NASA's Chandra X-ray Observatory that were released Monday. For the first time, scientists measured both...

    What about the recall race? After serious contemplation, it is clear that Arnold Schwarzenegger is the strongest candidate for governor. All Republicans should unite behind his candidacy to end the Gray Davis-Cruz Bustamante regime.

    The early sun produced powerful x-ray emissions that may have helped to ensure the survival of our planet, scientists say. Data from NASA's Chandra X-ray Observatory suggest that violent x-ray flares, which reached temperatures of 100 million kelvins, may have rocked the surrounding disk from which planets formed and prevented Earth from rapidly spiraling into the sun and being destroyed. An international team of astronomers focused Chandra on the Orion Nebula for 13 days, resulting in one of the instrument's deepest observations yet. Located 1,500 light-years from Earth, the Orion Nebula provides a way for scientists to study how our...

    LOS ANGELES - Solar flares are infamous for wreaking havoc on electrical power lines and communication signals. But a team of astronomers says bursts emitted by the sun in its youth may have helped planets form. Looking through NASA's Chandra X-ray Observatory, the astronomers focused on a cluster of young stars in the Orion Nebula, 1,500 light years from Earth. Studying 30 sun-like stars over two weeks, they found the young stars erupted in flares more powerful than those produced by the sun. The observation could explain how Earth survived during its formative years, astronomers said. Half the stars in...

    On January 18 Rep. John Conyers Jr., Michigan Democrat, told a placard-waving anti-war crowd: "The greatest patriots of this country are here today...The president said it'd be a cold day in Washington before this country turns against this war, but it is a cold day in Washington and here we are." Apart from Conyers nasty insinuation people who disagree with his leftwing views about war against the genocidal Saddam are not patriotic, what can we deduce from his presence? Well, for one, Rep. does not like America and prefers the company of totalitarians to that of genuine democrats. And how...

    Dark Matter Halo Puzzles Astronomers Summary - (Oct 26, 2004) Astronomers using the Chandra X-Ray Observatory have discovered a huge halo of dark matter around an isolated elliptical galaxy; an object that shouldn't have such a halo, according to optical observations. The galaxy, NGC 4555, is unusual that it's a large elliptical galaxy which isn't part of a larger cluster of galaxies. It's surrounded by a cloud of gas, twice the size of the galaxy itself, that's been heated to 10-million-degrees Celsius. This gas could only get that hot if it was being constrained by a halo of dark matter...
  • Joe Scarborough is Making Kerry's Case

    Joe S is engaging in fear mongering regarding the deficit. He just said that W took a record surplus (no mention that the surplus was an illusion brought on by the bubble economy) and turned it into record deficits. He is unmistakably trying to drive done W's support with his base. Now he has Buchanan on making the anti-Republican case too. Scarborough is such a nut. One minute he praises reagan (who had larger deficits than Bush does) and then he lights into Bush. This is insane. He is an incoherent jerk.

    This image shows Cassiopeia A in the most detailed image ever made of the remains of an exploded star. The colors represent different ranges of X-rays with red, green, and blue representing, low, medium, and higher X-ray energies of the supernova remnant. The one million second image shows a bright outer ring (green) ten light years in diameter that marks the location of a shock wave generated by the supernova explosion. A large jet-like structure that protrudes beyond the shock wave can be seen in the upper left. Chandra was launched July 23, 1999, aboard the Space Shuttle Columbia. The...

    Dark energy. Does it exist, and what are its properties? Using galaxy-cluster images from NASA's Chandra X-ray Observatory, astronomers have applied a powerful, new method for detecting and probing dark energy. The results offer intriguing clues about the nature of dark energy and the fate of the Universe. The Marshall Center manages the Chandra program. Astronomers have detected and probed dark energy by applying a powerful, new method that uses images of galaxy clusters made by NASA's Chandra X-ray Observatory. The results trace the transition of the expansion of the Universe from a decelerating to an accelerating phase several billion...

    For the second time in three months, scientists confirm that the universe is expanding at an ever faster rate thanks to a mysterious repulsive force called "dark energy" that counters gravity. The findings this time come from observations of the orbiting U.S. Chandra x-ray telescope. The latest batch of findings would probably have made renowned German physicist Albert Einstein exuberant were he still alive. He died in 1955 believing he had made a serious error in devising a concept he called the cosmological constant. He had created the notion in 1917 to explain why the universe did not collapse from...

    WASHINGTON (AFP) - For the first time ever, astronomers have detected sound waves coming from a massive black hole in space -- and believe the discovery may help resolve a major mystery, the US space agency said. The National Aeronautics and Space Administration said the Chandra X-ray Observatory had monitored for 53 hours noise coming from the central region of the Perseus galaxy cluster. The pitch of the sound waves, equivalent to a B-flat -- 57 octaves lower than a middle-C and at a frequency far deeper than the limits of human hearing -- is the deepest note ever detected...
