A group of criminal justice students at a small Atlanta college are preparing to launch their own investigation into the 2001 disappearance and slaying of Modesto resident Chandra Levy in Washington, D.C. Since 2005, students at Bauder College have sifted through old evidence and case files from unsolved crimes as part of the school's Cold Case Investigative Research Institute, according to institute director Sheryl McCollum. This year, Levy's homicide and the disappearance three years ago of Alabama teenager Natalee Holloway in Aruba are on their agenda.

Black holes are weird. Well, duh, right? But they do something that surprises most people: besides hoovering down almost everything nearby, they can also eject material as well. And by eject, I mean send it out screaming at nearly the speed of light and heated to a bazillion degrees. Picture from Chandra of the active galaxy pair 3C321 The image above is from the Chandra X-Ray Observatory, and it’s all about this scary scenario. Let’s take a walk down the gravity well, shall we? Basically, as matter swirls down into the maw of the hole, it forms a flattened disk...

Although he is no longer an FBI agent, Brad Garrett still visits the steep, wooded hillside in a Washington, D.C., park where the skeletal remains of Chandra Levy, a federal intern from Modesto, were found five years ago this week, a year after she disappeared. No one has been charged in the killing of the 24-year-old, whose disappearance generated enormous publicity after authorities revealed that she had been having a relationship with her married hometown congressman, Gary Condit. Condit was defeated in 2002 by his former aide, Dennis Cardoza. Read more at http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2007/05/22/CHANDRA.TMP

NASA's Chandra X-ray Observatory has captured the largest data set yet of Jupiter's colorful lights called aurora, yielding a pretty picture that could help solve some mysteries about the phenomenon. The phenomenon is similar to the Northern Lights seen on Earth, thought on a much larger scale. "Jupiter has auroras bigger than our entire planet," said Randy Gladstone of the Southwest Research Institute in San Antonio, Texas. In a NASA statement today, Gladstone called the purple rings in a new colorized image "Northern Lights on steroids. They're hundreds of times more energetic than auroras on Earth." Unlike Earth's auroras, Jupiter's...

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...

WASHINGTON (Reuters) - Dozens of massive stars, destined for a short but brilliant life, were born less than a light-year away from the Milky Way's central black hole, one of the most hostile environments in our galaxy, astronomers reported on Thursday. On Earth, this might be a bit like setting up a maternity ward on the side of an active volcano. But researchers using the Chandra X-ray Observatory and other instruments believe there is a safe zone around black holes, a big dust ring where stars can form. Black holes, including the one at the center of our galaxy, are...

The real fact It's amazing how Netaji Subhas Chandra Bose continues to be in news 60 years after his disputed death. In a way, this has been in defiance of successive Indian governments who would rather the people sidelined him as they did. A recent BBC online poll put named Bose the third greatest-ever leader in South Asia after Jinnha and Gandhi. Strikingly, as per the same poll, the stalwarts like Jawaharlal Nehru, Indira Gandhi and the inimitable Atal Bihari Vajpayee don't even blip on the radar anymore. The coming months will see Subhas making a comeback of a sort....

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 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.

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...
