According to astronomers, Centaurus A, one of the nearest galaxies to the Milky Way, is the brightest source of radio waves as seen from Earth. They say that, if humans could see these wavelengths, then the galaxy would occupy an area of the sky equal to 20 times the apparent size of the full Moon.One of the things t... |

Thanks to a new technology invented by members of the Engineering Faculty at Oregon State University, cleaning up nuclear contaminated sites will be more accurate, less expensive and much faster to complete.This new type of radiation detection and measurement spectrometer has been granted a patent, and the first devi... |

Waterproof clothes are very useful but the problem is that after washing them, they tend to lose their superhydrophobic properties, so a team of Chinese researchers finally developed the first waterproof fabric that maintains its properties even after 250 domestic washes at 40ºC.Researchers at the Chinese Academ... |

Experts have finally been able to confirm the existence of cosmic particle accelerators in our galaxy, the Milky Way, after years of studies. Astrophysicists have known for a long time that some galaxies have portions that are capable of acting like giant particle accelerators, forcing various particles to move at ne... |

In a groundbreaking new study, experts were able to determine that even nova explosions can cause the release of high-energy gamma-rays. This type of emissions was previously thought to be reserved exclusively for supernova explosions, the death throes of massive stars several times more massive than the Sun. Now, us... |

Gamma-ray bursts (GRB) are among the most peculiar phenomena in the Universe. Their sources are not very well known, although some evidence exists of possible origins. Since they were first discovered, some 50 years ago, they have sparked excitement in the scientific community, and have made astronomers believe that ... |

Astronomers using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), in Amado, Arizona, have recently announced that they discovered very high energy (VHE) gamma-ray emissions coming in from the starburst galaxy M82, also known as the Cigar Galaxy. According to the team, the radiations are very po... |

For all its massive size, our galaxy, the Milky Way, is a bit slow when it comes to forming new stars. This is not the case with other large galaxies, which produce young, blue suns at very high rates. These areas of intense star production, known as stellar nurseries, have long been associated with radiation, and a ... |

The new film created by the NASA American space agency makes clever use of scientific observations made by Fermi's Large Area Telescope (LAT) in its first 87 days of operations, and depicts the Universe in a manner that has rarely been seen before. Active galaxies near and far flare up as the time passes, and th... |

The brightest galaxies that the Fermi Space Telescope sees are the most active in terms of radio emissions, but, at times, the observatory alone is not capable of peering very deep into the stellar formations. When lots of data gather, and a better tool is needed, experts turn to the world's largest radio observ... |

The Indian Space Research Organization (ISRO) has announced that the Chandrayaan-1 lunar orbiter captured an X-ray burst coming from the Moon's surface on December 12th, which is excellent new because, theoretically, the camera that recorded the burst was not sensible enough to pick up such trace amounts of radi... |

Astronomers at NASA are thrilled that, following the launch of the new Fermi Gamma-ray Space Telescope, new pieces of information about the make-up of pulsars are coming up for the first time in 40 years. Since these unusual stars were first discovered, scientists have wondered as to what their actual power is, seein... |
