Recent astronomical observations found a cosmic phenomenon that shatters previous records for the lowest stellar temperature at which radio waves can be produced. Researchers were able to find flaring radio emissions coming from an ultra-cool, brown dwarf-class star.
Brown dwarfs are often referred to as failed star... |

Researchers at the Massachusetts Institute of Technology (MIT) announce the development of a series of algorithms that enables a Magnetic Resonance Imaging (fMRI) machine to conduct its scans in about 15 minutes, as opposed the 45 minutes it needs to complete a scan today. Patients are nowadays asked many times to ... |

Researchers with the Lincoln Laboratory at the Massachusetts Institute of Technology (MIT) announce the development of a new type of radar technology, which enables users to see through walls. This would have seemed the stuff of science-fiction only a few years ago. In order to understand this innovation it's i... |

Radio wavelength emissions recorded from filaments located within our galaxy may in fact represent a definitive proof that dark matter indeed exists. Astronomers discovered these central galactic filaments some years ago, but had no way of explaining them until now. In the new study, experts are proposing that the em... |

Studies conducted using a NASA orbiter are showing that the radio waves emanating from both the north and south pole on Saturn are different in their variations. Researchers say that these variations also change with seasons, and that the wave characteristics were even exchanged between the poles. At one point in tim... |

A few years ago, atmospheric scientists discovered an peculiar phenomenon taking place as lightning strikes were headed to Earth – the generation of a flash of radiation accompanying the event. Now, the cause of these flashes is beginning to be revealed.Called gamma-ray flashes (GRF), these phenomena are charac... |

Astronomers were recently able to use the NASA Fermi Gamma-Ray Space Telescope to take a look at the nearby galaxy Centaurus A, and what they saw puzzled them. The cosmic structure releases ten times more radiation in gamma-ray wavelengths than it does in radio wavelengths.
This is peculiar because the galaxy is i... |

Astronomers believe that they may have developed a new way of searching for extrasolar planets. They believe that massive, Jupiter-class planets may exhibit powerful aurora displays. If that is the case, then the radio waves these light shows produce should be easily distinguishable from Earth.The technique is especi... |

Investigations carried out with the NASA Cassini orbiter around Saturn have revealed that the gas giant is sending out mixed radio signals. The planet's rotation causes variations in the radio waves it releases, but these variations are different between the northern and southern hemispheres.In addition, it was ... |

In a new scientific study, experts propose that we attempt to use neutrinos in our quests to establish contact with potential extraterrestrial civilizations that may exist elsewhere in the Universe. Until now, all messages that we sent into space were delivered via radio waves. We were accustomed to using this type o... |

In a new investigation, scientists have finally been able to determine precisely what is it that creates the peculiar faint glow that lies above Earth atmosphere, called the diffuse aurora. At latitudes where auroras are visible, the atmosphere also shows signs of residual light, and the origin of this phenomenon ha... |

Scientists from a group of universities in the United States are currently working on developing a new technology for identifying bombs and improvised explosive materials inside shielding materials. The method would ensure that even components that are very carefully hidden could be detected by using sound and radio ... |

A group of scientists announces the development of a novel method of determining the combined weight of all the planets in the solar system.The approach relies on analyzing the radio signals emitted by distant magnetars, which are a very particular type of neutron stars. These structures appear in space after massive... |

Saturn is undoubtedly one of the most interesting cosmic bodies in the solar system, this being one of the main reasons why NASA and ESA decided to send the Cassini-Huygens mission to investigate it. Over the past six years, we gained a wealth of new data on the planet, but some mysteries still endured. One good exam... |

A team of scientists has found another use for wireless networks, other than transmitting data from one terminal to another. According to a research paper it just made public, wireless technology can be used to reveal what's going on behind closed doors, or through a wall. The team, based at the University of Ut... |

The southern constellation of Centaurus, located approximately 14 million light-years away, is home to two very important things – the massive galaxy Centaurus A and a monster black hole, which has about 50 million times the mass of our Sun. The galaxy, for some reason, cannot be viewed very clearly in optical ... |

In a surprising turn of events, experts at the Los Alamos National Laboratory (LANL), the same involved in the creation of the first atomic bomb, have announced the creation of radio transmitters that incorporate a radio wave source that moves faster than the speed of light (superluminally). Behind the amazing achiev... |

Soon, the first set of “ears” for the Atacama Large Millimeter Array (ALMA) telescope, which is currently under construction in Chile, will be shipped out from England. The UK is in charge of delivering the first receivers for the international project, which will create a telescope that totals the observ... |

I'm certain that most of the people reading this article have noticed at some point in time that some of the cables connecting the peripherals to a personal computer have some strange looking 'bumps' (see lower image). If you did, then you might have also asked yourselves what those things are and what... |

The Van Allen radiation belt consists of two concentric zones inside of which charged subatomic particles are being trapped by Earth's geomagnetic field. The outer belt is able to capture particles from the solar wind and retain them for as long as a week, while the inner belt could keep particles trapped inside... |

Jupiter and Earth, two extremely different planets. One has a solid surface, the other has no surface at all; one is a rocky planet, the other, a massive gas giant, and so on. However, this doesn't mean that the two are totally different from one another. It looks like Jupiter and the Earth share one key feature... |

Well... not you specifically, just your computer! After some extensive upgrades of the Arecibo radio telescope which included, aside the first paint job in more than four decades, the installation of seven new radio receivers that allow the telescope to extend its radio spectrum to over 40 times that of the original... |
