A new international astronomical cooperation effort, led by experts at the Cardiff University, in the United Kingdom, has brought to light new evidence that the standard cosmological model in use today, which includes the existence of dark matter and dark energy, is in tune with reality. The proof was collected using... |

It has become widely accepted among scientists that our Universe is roughly 13.7 billion years old. It's also known that the diameter of the observable Universe measures at least 93 billion light-years. However, if this is true, there is a hitch. In 13.7 billion light-years, light can only travel 13.7 billion li... |

The recently launched Planck telescope finally began to observe the Universe on August 13th, during a test-observation period. Built specifically by the European Space Agency (ESA) to analyze the Cosmic Microwave Background (CMB), the relic radiation left behind when the Cosmos first exploded into being, the telescop... |

The recently launched Planck telescope has just begun observing the early Universe, accumulating background radiation that was most likely created when the Universe first sprung into being. The mission is conducted by the European Space Agency (ESA), with vast collaboration from NASA. In addition to the observatory, ... |

Experts from the US Department of Energy's (DOE) SLAC National Accelerator Laboratory, the Michigan State University, and the Stanford University have recently managed to use computer models to simulate the way in which the first twin stars in the very early Universe were formed. Stretching as far back as 200 mi... |

The level of complexity at which Planck does its science never failed to amaze anyone looking deeper into its capabilities. In addition to the peculiar point in space where its orbit lies, at the Lagrangian point 2, some 1.5 million kilometers away from us, it also features another remarkable trait – it's ... |

Today, the ESA-operated Guiana Space Center, in South America, will launch an Ariane 5 delivery system, which will carry two new space telescopes, Herschel and Planck, to a transfer orbit. After several delays, the mission was finally confirmed a few days ago, and everything looks set for today's launch. The two... |

The theory that holds the Big Bang responsible for the creation of the Universe is one way of explaining how everything around us came to be, but it also raises questions as to what happened in those early moments, when the basis for all that exists today was set. More specifically, experts wonder what happened in th... |

What was before this universe is currently anybody's guess, but it is highly likely that it was preceded by a similar universe and therefore time existed before the Big Bang. The evidence to back this theory is said to be found in the Cosmic Microwave Background radiation left behind by the light created when th... |

Approximately a decade ago astronomers discovered that not only is the universe expanding in space-time, but also that this expansion is accelerating. Since there was no explanation to why this is happening, they proposed the concept of dark energy, a form of energy that makes up about 75 percent of the mass of the u... |

In November last year astronomers reported having discovered a large cold spot in the CMB radiation, coinciding with a void about one billion light years across in the Eridanus constellation, the biggest void in cosmos, or the hole in outer space as some named it. According to calculations, the respective volume of s... |

They say the string theory is not real science, but merely a science fiction description of the universe. This is mostly due to one thing: the string theory makes predictions than cannot be tested in real life, thus it cannot be proven and is falsifiable. For example, the string theory proposes that elementary partic... |

Current theories about the beginning of the universe predict that all the observed matter originated in a single point in space, a singularity, which suddenly expanded in space-time provoking the so-called Big Bang. The light emitted by the glowing matter in the beginning of the universe slowly shifted towards the in... |

In August this year, astronomers studying the Cosmic Microwave Background Radiation or CMB, a 'remnant' of the Big Bang, discovered a texture of a giant cold spot in the universe, completely empty of any normal matter or dark matter and even any kind of radiation. In order to explain how such a void might h... |

Data collected by the Wilkinson Microwave Anisotropy Probe or WMPA is not flawed, but rather contaminated with radio radiation coming from our galaxy. The WMPA is a satellite, launched in 2001 by NASA, to probe the Cosmic Microwave Background or CMB, and find minute differences of temperature to test certain theories... |

This is a review of the top ten strangest things in space that scientists still study and try to formulate, theories that open our imagination to new horizons and new technological possibilities. 1. Antimatter - all the things we know and see are made out of matter and energy. For a long time it was thought that ato... |

The microwave background radiation is a remnant of the cosmic radiation of Big Bang. It was discovered in 1965 by scientists at Bell Laboratories, almost by mistake during a satellite communication experiment. This electromagnetic radiation fills the entire universe, has a thermal 2.725 kelvin black body spectrum, w... |
