The massive IceCube neutrino detector, buried in the Antarctic, has detected a total of 28 neutrinos that could have extraterrestrial origin. Scientists are excited about the discovery, as it could be a first step towards a completely new way of doing astronomy. Neutrinos are weakly-interacting particles. They are v... |

The century old mystery of the origin of cosmic rays has been cracked, finally, as astronomers are now certain that they originate from supernova blasts, as has long been the belief. Despite the widely accepted premise, there was little concrete proof until now. Cosmic rays are high energy particles, much more energ... |

One of the main problems that remain to be solved before we can send astronauts on long-term space exploration mission is that of cosmic radiation. The surfaces of Mars and the Moon are bathed in the stuff, but German researchers are currently investigating a solution that may help.
Scientists based at the GSI Helm... |

Astronauts aboard the International Space Station (ISS) say that they can apparently perceive cosmic rays. The radiation appears as dots, streaks or clouds on their retinas, even when their eyes are closed.
The phenomenon is caused by the fact that the orbital outpost provides only limited protection against this e... |

An in-depth survey of the sky, conducted using a massive, underground particle detector at the South Pole, has revealed that the production of cosmic rays is a more mysterious phenomenon than experts had first predicted. The theories currently trying to explain where these rays originate may all be wrong.
The new st... |

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... |

Investigations conducted with a number of dedicated observatories around the world have revealed that some locations in the sky are cosmic ray “hot spots,” whereas others are relatively inactive in this area. The Vela supernova remnant was recently determined to be such a hot spot. One of the instruments ... |

A new study proposes an interesting explanation for the regular variations that the biodiversity on our planet exhibits almost like clockwork. Experts now believe that the wobbling path our solar system takes as it's traveling through the Milky Way may have something to do with this. One such extinction event ta... |

Using a series of datasets from several spacecrafts and observatories, experts have determined that the amount of cosmic rays the Earth was subjected to in 2009 was the largest ever recorded. Experts who conducted the measurements said that in no other period since the beginning of the Space Age have so many radiatio... |

According to a new scientific investigation, it may be that our planet's atmosphere is capable of forming massive energy fields high above Earth's surface that act just like particle accelerators. The conclusions were presented today, April 14, at the Royal Astronomical Society (RAS) National Astronomy Meet... |

No more than three years ago, experts using a large telescope array in Argentina published a paper proposing a possible source for the peculiar space phenomena that are cosmic-rays. This type of radiation is composed of highly-energetic particles, whose origins are a complete mystery. The investigators said in 2007 t... |

Cosmic rays are streams of protons that occasionally slam into the planet's atmosphere at speeds close to that of light. While their effects have been identified and studied extensively, astrophysicists have had a hard time figuring out where they originate. A leading explanation is that supernovae somehow produ... |

The amount of cosmic rays circulating in the solar system should be of interest to everyone. As the Sun gets weaker over the course of the solar minimum, more and more radiation reaches our planet, passes the atmosphere and heads down to the earth. Apparently, not all its effects are bad. Experts in the United Kingdo... |

According to experts at the American space agency, the concentration of cosmic-ray radiation around us has increased considerably this year, reaching its highest level in more than 50 years of observations. The level of cosmic rays has been under constant surveillance since the advent of the space age, and such a sha... |

Cosmic radiations permeate everything around us at all times of the day. Some of them are generated near us, on a radius of a few thousand light-years, while some only reach our planet after a ten- to 11-billion-year journey. They are unnoticeable to humans, but some researchers believe they may have played a crucial... |

Planetary scientists have known for a long time that several billion tons of water disappear from Earth's atmosphere each year, as if by magic. However, despite having this knowledge, explaining why this happens has turned out to be a very tricky question. Now, Technical University of Denmark (DTU) National Spac... |

Finding traces of the elusive dark matter is no easy task, as any astrophysicist scouting all parts of the sky can tell you. In theory, it may be possible to detect it using several means, but, thus far, all efforts have been in vain. It would appear, some say, that the best bet for finding dark matter during this ge... |

Not long ago, scientists tracked down the origin of cosmic rays to supermassive black holes located in the cores of active galactic nuclei. Cosmic rays are streams of high energy subatomic particles coming from intergalactic space. Ultra-high-energy cosmic rays, however, are far more energetic than usual cosmic rays,... |

The first of these objects, 2003 EL61, was discovered back in 2005 and appears to be a strange shaped body rotating rapidly and chaotically about its axis. The fact that other five objects were found in the same orbit in 2007 suggests that all may have originated from a larger object destroyed during a collision abou... |

Earth, like many other bodies in space, is constantly being bombarded with streams of highly energetic sub-atomic particles of matter, coming from all directions. But, while some emissions of particles inside the atmosphere can be explained relatively easy, one type of cosmic rays remained, so far, mostly a mystery. ... |
