Credit: Aaron Kaase/NASA/Goddard A newly discovered belt of antimatter circling Earth could be an astronaut's best friend. The belt, which consists of antiprotons trapped by Earth's magnetic field several hundred kilometers above the planet's surface, may ultimately become a key source of fuel for missions venturing beyond the solar system. Researchers analyzing data from the PAMELA (Payload for Antimatter/Matter Exploration and Light-nuclei Astrophysics)...

New candidate for most distant object in universe
Posted by admin / Under Astrophysics Data System
A gamma-ray burst detected by NASA's Swift satellite in April 2009 has been newly unveiled as a candidate for the most distant object in the universe. At an estimated distance of 13.14 billion light years, the burst lies far beyond any known quasar and could be more distant than any previously known galaxy or gamma-ray burst. Multiple lines of evidence in favor of a record-breaking distance for this burst, known as GRB 090429B for the 29 April 2009 date when it was discovered, are presented in a paper by an international team of astronomers led by former Penn State University...

Betelgeuse 'not likely to explode in 2012'
Posted by admin / Under Astrophysics Data System
THE super-giant red star Betelgeuse in the constellation of Orion is destined to explode, but maybe not next year as some recent news reports have suggested and will not be as bright as some predicted FoxNews.com reported Betelgeuse has already become a red giant, which indicates it wil explode and become a supernova. But experts say it is not likely to happen soon and it will happen far enough away that it wil not hurt Earth US astronomer Phil Plait noted on his blog that a supernova would have to be no farther than 25 light years away to "fry...

Hyperfast Star Was Booted from Milky Way
Posted by admin / Under Astrophysics Data System
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 Pioneer Anomaly, a 30-Year-Old Cosmic Mystery, May Be Resolved At Last
Posted by admin / Under Astrophysics Data System
Thirty years ago, NASA scientists noticed that two of their spacecraft, Pioneer 10 and Pioneer 11, were veering off course slightly, as if subject to a mysterious, unknown force. In 1998, the wider scientific community got wind of that veeringtermed the Pioneer anomalyand took aim at it with incessant, mind-blowingly detailed scrutiny that has since raised it to the physics equivalent of cult status. Now, though, after spawning close to 1000 academic papers, numerous international conferences, and many entire scientific careers, this beloved cosmic mystery may be on its way out. Slava Turyshev, a scientist at the Jet Propulsion Laboratory...

Who says the Sun controls our weather and climate? An interview with astrophysicist Piers Corbyn
Posted by admin / Under Astrophysics Data System
When I think of all the evidence I have been presented with over the past several years regarding the main driver of our climate, one man stands tall. That would be Piers Corbyn, founder of WeatherAction.com in the UK. He does long range weather and climate predictions and his accuracy is amazing, especially for the extreme events all based on the Sun. I had seen his forecasts on the web but I had my first chance to talk with him in person at the 2008 International Conference on Climate Change in New York put on by the Heartland Institute. It...

Planet Found With Comet-like Tail
Posted by admin / Under Astrophysics Data System
HD 209458b, shown in red in an artist's conception, is the first confirmed "cometary planet," experts say. Image courtesy G. Bacon, NASA/ESAAn alien planet orbits so close to its star that its atmosphere is being blasted away, forming a gaseous, comet-like tail, astronomers announced Thursday. (Related: "Odd Star Sheds Comet-like Tail.") About 153 light-years from Earth, planet HD 209458b hugs its star so tightly that the planet's atmosphere is likely a scorching 2,000 degrees Fahrenheit (1,093 degrees Celsius) an a year passes in just 3.5 daysmaking Mercury's 88-day orbit seem downright leisurely.That tight orbit also means this gas giantmeaning...

Star Keeps Magnetic Lock on Its Big Brother

Peterson et al./NRAO/AUI/NSF Taking advantage of an unusual pair of nearby stars, astronomers have for the first time captured images of a magnetic field generated by a star other than our sun. Studying that field should help researchers gain a much better understanding of the internal dynamics that produce stellar magnetic fields, which in our sun's case can influence everything from climate to satellite orbits to telecommunications. Astronomers have indirectly detected magnetic activity associated with other stars. But because of the great distances and the...

Astronomers witness biggest star explosion
Posted by admin / Under Astrophysics Data System
Massive supernova produced rainbow of elements for months. Bang! The collapse of a massive star created a previously unseen type of supernova.NASA Astronomers have watched the violent death of what was probably the most massive star ever detected. The supernova explosion, which lasted for months, is thought to have generated more than 50 Suns' worth (1032 kilograms) of different elements, which may one day go on to make new solar systems. The explosion dubbed SN2007bi was spotted as part of a digital survey to hunt for supernovae at the Palomar Observatory near San Diego, California. One supernova in...

Beauty from the Bottom of the Universe (astrophysicist speaks on faith and science)
Posted by admin / Under Astrophysics Data System
Ancient radiation, the birth of the universe and the future of the galaxies around us: for Marco Bersanelli, a professor of astrophysics at the University of Milan, such mysteries are all in a days work.For the past 17 years Bersanelli has been a member of the science team of Europes recently launched Planck observatory, a telescope currently orbiting the sun 1.5 million kilometers from Earth in a mission to map traces of radiation left over from the Big Bang 14 billion years ago. Essentially, Planck is grabbing images of the universes earliest light and, hopefully, clues as to how the...

New astrophysical discoveries leave little to no room for Atheism, expert says
Posted by admin / Under Astrophysics Data System
Denver, Colo., Sep 30, 2009 / 03:35 pm (CNA).- Contemporary astrophysics hold the scientific key to prove the existence of God, but unfortunately very few know the scientific facts, said Fr. Robert J. Spitzer, S.J, PhD, during a conference delivered on Sunday at the John Paul II Center for the New Evangelization in Denver, Colorado. The Honolulu-born Jesuit is the past president of Gonzaga University and is also well-known philosopher and physicist who is involved in bringing science and theology together. Fr. Spitzer is currently engaged in an ambitious project to explain the metaphysical consequences of the latest astrophysical discoveries,...
