On Saturday, January 14, the High Frequency Instrument (HFI) aboard the European Space Agency's (ESA) Planck spacecraft ran out of its absolutely-essential coolant. While this marks the end of HFI's operating life, it also marks the completion of the first survey of residual light from the Big Bang.
After... |

Officials at the European Space Agency (ESA) say that the first all-sky survey scheduled to be carried out by the High Frequency Instrument (HFI), aboard the ESA Planck spacecraft, has just been completed. The study finally reveals a map of the residual one left behind by the Big Bang.
The representatives also said ... |

During the latest investigation researchers conducted on the nature of dark energy, it was discovered that the stuff was only minimally-present in the early Universe. At this point, dark energy accounts for more than 74 percent of cosmic density.
However, a short while after the Big Bang, the stuff only accounted ... |

Physicists have recently taken an interest in testing to see whether the Multiverse hypothesis is correct or not. This idea holds that the entire Universe is contained within a bubble, which is itself just one of many such bubbles in the Multiverse. Though this idea has been proposed some time ago, experts are only n... |

For years, astronomers have been proposing that the Milky Way and other galaxies in the Local Group are being drawn towards a dark mass called the Great Attractor. New data from telescopes in Chile are showing that that may not be the case at all.
This mass was proposed to exist in order for experts to be able to... |

Using the latest astronomical techniques and equipment, experts were recently able to map out the distribution of matter across the distant Universe, and found it to be more clumped up together than theories would have suggested. The work also provides more evidence that dark energy is real. In order to gain a better... |

If astronomers will exist in the year one trillion, they will find it extremely difficult to conduct astrophysical and cosmological research, a team of experts believe. By that time, most of the guidelines we use for studying the Universe would have long-since disappeared. As current observations indicate, the Cosmos... |

Researchers suggest in a new study that the telltale signs showing us today that the Big Bang actually existed may disappear entirely within about 1 trillion years. Our most distant descendants will have a very tough time figuring out what happened in the early Universe. The Big Bang model is now the most widely-acce... |

Investigators have recently taken a closer look at a background layer of subatomic particles, that was found some time ago to permeate the entire Universe. Similar to the cosmic microwave background (CMB), this collection of particles was also produced in the earliest moments of the Cosmos. This subatomic signature s... |

A famous theoretical physicist in the United Kingdom argues that space and time were not something that appeared when the Big Bang spawned the Universe into being. In fact, they may be much older constructs that simply underlie this Cosmos as they did many other before it. University of Oxford physicist Roger Penrose... |

This standard is set by results obtained with the WMAP satellite.The spacecraft spent years analyzing the Cosmic ... |

The most recent investigations conducted on the earliest days of the Cosmos have revealed that the Big Bang was followed by several hundred million years of darkness, in which absolutely no light was produced. The first stars and galaxies began developing after that period.Because of the total lack of light, those ea... |

Astronomers have determined that the entire Universe is permeated by what could best be described as an ancient signature at a subatomic level, which may yield additional details about how everything came into being. Some of the particles in this signature apparently have the ability to exist in a large number of pla... |

Astrophysicists are currently investigating a phenomenon called “dark flow,” which may be pulling on matter at the edge of the Universe in a way that cannot be explained by current data.

Astronomers recently announced the discovery of an impressively-large cluster of galaxies in the early Universe, that has somehow eluded detection until now.

The most widely-accepted model of how the Cosmos is set up shows us that only about 4 percent of the Universe's mass-energy budget is made up of normal matter.

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... |

Approximately a decade ago astronomers discovered that not only is the universe expanding in space-time, but also that this expansion is accelerating.

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... |
