According to the conclusions of a new scientific study, it would appear that the reversal of Earth's magnetic poles occurs in cluster, in what may very well imply the existence of some sort of “memory” of past instances in which these events have happened. Geological evidence indicate that the last p... |

By combining the infrared capabilities of the NASA Spitzer Space Telescope with the shorter-wavelength infrared and visible ones from the Subaru Telescope, in Hawaii, astronomers recently managed to obtain an amazing view of a distant cluster of galaxies.
The large cosmic structures appear only as tiny red dots i... |

When cosmologists looked to see what happens at the boundaries of the Universe, they noticed something that no one expected – a tendency of the most massive galaxy clusters in existence to head towards a single hot spot in space. Why this happens is still a mystery.
Exploring the boundaries of the known Cosm... |

Astronomers with the European Space Observatory (ESO) have recently identified a dwarf galaxy that lies within one of the massive voids that forms between large-scale structures in the Universe. At the macroscale, the Cosmos is very different than astronomers took it to be in theoretical research. Galaxies have a ten... |

The long-held idea that the first stars in the Universe were lone wolves may not be true at all, the results of a new study show. In fact, it could be that the earliest stars to shed light on the Cosmos had numerous companions around themselves.These so-called companions may have developed when the original gas disks... |

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. The concept was developed when researchers observed motions in the large structure of the Cosmos that shouldn't ha... |

For many years, astrophysicists have been debating the role that supermassive black holes play in the galactic development process. Galactic temperatures are among the main factors dictating the evolution of this type of structures, and experts have recently found the perfect place to investigate the relation.The gal... |

In a new series of observations, a team of investigators has recently shed new light on a galaxy located in the large Coma Cluster. The cosmic structure looks stunning in a new photo. The new observations were conducted using the Hubble Space Telescope, which was last year revamped, and outfitted with new cameras a... |

Over the past few years, astronomers surveying the skies noticed that the brightest, most massive galaxies appeared to be occupying only specific regions of the Universe. The correlation was strongest for older cluster, some up to 10 billion years old. Puzzled by this trend, an international group of researchers dec... |

White dwarfs are omnipresent in the Universe. They are generally seen as representing the final stage in an average star's evolution, and are thought to form when a Sun-sized stellar object can no longer sustain nuclear fusion. Astronomers have known for a long time that analyzing these objects may yield some in... |

Astronomers from Germany and Japan announce the discovery of the most distant galaxy cluster ever identified in the Universe. While single galaxies, stars and black holes have been found existing farther away than this, the experts underline the fact that this is the oldest, fully-formed galaxy cluster discovered. Th... |

Astronomers at the European Southern Observatory (ESO) have just released a new spectacular, wide-field image of a very crowded portion of the sky. The photograph covered several thousands of very distant galaxies, according to the team behind the study, as well as a significant group of such structures that are incl... |

A series of recent experiments has revealed that, more often than not, the halos of dark matter surrounding massive galaxy clusters are flattened and shaped like a cigar. Until now, astrophysicists believed that the mysterious stuff, which is believed to be five times more abundant than regular matter around the Univ... |

Without a doubt, galaxy clusters are the largest coherent structures in the known Universe. They are made up of hundreds of thousands of galaxies, all held together through the force of gravity. While it may be difficult to observe clusters at first, careful analysis of how seemingly-unrelated galaxies move soon hint... |

When peering at the night sky through any telescope, the stars appear to be still. In fact, they've maintained the same relative position towards Earth since mankind started taking an interest in them. But astronomers have recently detected that a number of clusters of galaxies travel through the Universe along ... |

One of the most difficult-to-achieve goals in astrophysics today is establishing the approximate weight of the universe. This can be done by combining two sets of data, one that estimates the mass of all visible matter in the Universe, and another that attempts to put some values on the mass of dark matter that lurks... |

Astronomers believe that, many years ago, when our galaxy was still in its infancy, it collided with a dwarf cousin, giving birth to a host of processes, including the development of a stellar cluster. As the Milky Way went on to grow to the impressive sizes it has today, the “fossilized” stellar cluster ... |

Using the Advanced Camera for Surveys (ACS) instrument aboard the newly refurbished Hubble Space Telescope, astronomers have recently snapped an amazing, highly detailed image of the galaxy NGC 4710. In its analysis of the images, the team discovered that the structure revealed an X-shaped bulge that was uncharacteri... |

Astronomers handling the Chandra Space Telescope, one of NASA's four Great Observatories, have recently announced they they've discovered one of the most distant clusters of galaxies in the Universe, located at a distance of about 10.2 billion light-years away from our planet. According to the experts, the ... |

A team of physicists from the University of Michigan (UM) announce the creation of the world's first atomic-scale map of the promising quantum dots, semiconductors whose excitons are confined in all three spatial dimensions. Quantum dots potentially have the ability to influence a large number of production proc... |

For quite some time now, astronomers have known that galaxies are not held together in the Universe by gravity alone, but that they are neatly placed along a scaffolding, which holds them and moves them around. After some time, astrophysicists have inferred that this support structure is also responsible for funnelin... |

The Constellation of Indus has recently revealed another of its galaxies to the Hubble Space Telescope. Dubbed the most important observatory in the history of astronomy, Hubble has managed to identify the NGC 7049 galactic formation in the Southern constellation, and to reveal that it has a very peculiar shape, some... |

The team operating NASA's Hubble Space Telescope believes it may have uncovered renewed evidence of the fact that all galaxies are “embedded” in a cocoon of dark matter, the invisible substance that is believed to keep them and clusters all together. During a recent survey of the skies, the observato... |

The northern constellation of Coma Berenices is home to one of the closest and brightest galaxy clusters astronomers are familiar with, namely the Abell 1656, also known as the Coma Galaxy Cluster (CGC). This formation holds up to 1,000 galaxies, most of them elliptical. However, one of them, which happens to be a sp... |
