In two papers published in the December 1 issue of the top scientific journal Nature, investigators describe two possible explanations for an extremely-weird gamma-ray burst astronomers detected on Christmas Day 2010.
The event was first detected by the NASA Swift spacecraft, and cataloged as GRB 101225A. The main r... |

In a recent study, an international collaboration of astronomers was able to analyze a bright gamma-ray burst (GRB) that occurred in the distant Universe. The reason why this particular flash of light is so important is because it passes through two very old galaxies before finally making its way to Earth.
In essenc... |

Cosmic collisions and explosions taking place as far away as the other side of the galaxy could pose a significant risk to life here on Earth. This class of events has the potential to trigger the release of unfathomably-large amounts of radiations, which the magnetosphere will not be able to deflect.
Usually, our... |

A collaboration of researchers from the University of Warsaw (FUW) Faculty of Physics and the University of Naples Federico II announce the development of a new method for measuring cosmic distances. They say their approach uses the properties of gamma-ray bursts for this purpose.
In addition to the obvious use in... |

According to a new line of thinking among astrobiologists, it may be that one of the main reasons why we have yet to hear from, or make contact with, extraterrestrial civilizations is the fact that powerful, violent cosmic events wiped them out.There are plenty of possible culprits for such a scenario, scientists rev... |

A group of scientists proposes that the origin of a hybrid gamma-ray burst they observed some time ago may have been a white hole. There is no other way to explain why the event unfolded with the intensity and duration it did, they add.In order to understand why the team made this proposition, we must first look at G... |

Experts at the American space agency have just produced the most detailed account of how short gamma-ray bursts (GRB) are formed from the collision of two neutron stars. The work will certainly become a reference point in this field, which deals with explaining the most energetic events in the Universe. The origins o... |

Over the past few days, a large number of online, science-related news sites have reported that the massive star Betelgeuse will explode in 2012, in a large supernova event that will be visible from Earth. In fact, reports say that the explosion will appear as a second Sun. This is all false, experts say.A supernova ... |

Following the biggest and most comprehensive study to date on gamma-ray bursts, experts have now made sense of the factors that make some of the most energetic events in the entire Universe to appear dim when seen in visible light wavelengths. When looking at this energetic light in the gamma-ray portion of the elect... |

In a new series of studies, astrophysicists managed to determine what is left behind after the collapse of massive stars, which release most of their energy as gamma-ray bursts. GRB are the most violent explosions in the Universe, and apparently they can produce certain kinds of neutron stars.According to investigati... |

At a recent conference, a team of researchers presented new discoveries showing that a special class of of neutron stars, called fast-spinning magnetars, is responsible for a large part of all gamma-ray bursts (GRB) that have been noticed in the Universe thus far. Experts knew that the structures are involved, but un... |

Black holes have captured the imagination of scientists, movie producers and common folk over the years, because of their amazing traits and structures, and also due to the fact that they are unique in their own regard. There is nothing else in the Universe that resembles a black hole, or that can absorb and trap li... |

Astronomers have finally discovered proof that confirms a long-held belief, namely that the shock waves generated by supernova explosions act like giant and extremely powerful particle accelerators. They came to this conclusion when they recently discovered that cosmic-ray particles, generated only when a massive sta... |

Try taking a look at the night sky for a while, from time to time. It's kind of boring, isn't it? Nothing ever happens, there is peace and quiet everywhere you look. Or is it? Astronomers say the universe is a chaotic place, where massive explosions take place all the time in order to release large amounts ... |
