New investigations are proving that the evolution of galaxies is a complex and continuous process, and one that does not conclude once a galaxy reaches a certain mass or size. The phenomenon continues over billions of years, but the way in which the cosmic structures grow differ. Early on, when a galaxy is just formi... |

Recent investigations conducted on the massive spiral galaxy NGC 4013 is revealing an overlooked aspect of the formation, the fact that its odd shape is a direct result of the tidal interactions it's having with a close-by companion.The two galaxies are in fact almost entirely merged, with only a massive tidal s... |

In a new scientific research, experts were able to figure out that black holes across the Universe are today spinning a lot faster than they used to when the Cosmos was only a fraction of its current age. The reasons why this happens remain unexplained, but investigators are proposing a series of theories that might ... |

Astronomers are currently keeping a close eye on the evolution of an interesting binary star system, which features two white dwarfs. The two objects are apparently about to merge, an event that will lead to the formation of a new, living stellar object.White dwarfs are the helium-burning remnants of Sun-sized stars ... |

Astronomers are currently in the process of refining their original predictions about the fate of the Andromeda-Milky Way galactic system. They say that it could be possible the two objects will not hit each other after all. The earliest predictions about a potential collision were based on the fact that our neighbor... |

Astronomers analyzing the Milky Way have many years ago observed the existence of a thick disk of stars in its central regions, in addition to the thin disc that makes most of the galactic body. However, a similar structure was not found in the Andromeda Galaxy, our closest neighbor. Experts have been looking for a t... |

Since quasars (quasi-stellar radio sources) were first identified, a scientific debate has erupted over how to best define these space structures. Some understand them as being highly energetic and distant galaxies that have an active nucleus, whereas most think that they are the compact regions in the center of larg... |

It is common knowledge that active galaxies tend to include one or more stellar nurseries inside themselves. These are areas of intense stellar formations, where the conditions are just right for stars to form. The rate at which new suns are produced is entirely dependent on environmental factors, such as the amount ... |

While investigating nearby galaxies, including our closest neighbor Andromeda, astronomers were surprised to discover that most of them showed signs of having gobbled down smaller galaxies. The structures, too small to make it on their own around the giants they orbited, were cannibalized and became a part of the mas... |

According to scientists at the University of Bonn Argelander-Institut fur Astronomie, in Germany, it may be that astrophysicists will soon be able to observe the collisions of tens of pairs of black holes in star clusters. The team believes that the technology to allow for such direct observations may find its way in... |

One of the biggest unanswered questions regarding the Universe today is why there are two types of galaxies, one that has trailing spiral arms, such as our own Milky Way, and one that looks more like a compact ball of stars, known as a barrel galaxy. Astronomers have struggled with this question for a long time, and ... |

While investigating the skies in search of colliding galaxies, astronomers working with the Subaru telescope, on Mauna Kea, in Hawaii, have discovered what amounts to the skid marks left behind by cars before crashing. Debris ejected by two galaxies while approaching each other and during their collision form a path ... |

According to a new scientific study released by experts at the Indiana University, some massive galaxies may have formed relatively recently, just three to four billion years ago. Astronomical “dogma” holds that the most massive and luminescent galaxies in the Universe, such as our own Milky Way, were for... |

Everything is crystal clear for a while now: the future of video games will be in the hands of three or four huge game developers created from mergers and buy-outs (and tender/hostile takeovers, probably). One of the latest companies that seems to have understood that is Square Enix which, ironically, was formed as a... |

It's not the first time - and probably not the last either - when your galaxy commits acts of cannibalism against its smaller companions orbiting around it. Researchers from the Research School of Astronomy at the Australian National University reveal that they have discovered debris of a possible encounter betw... |
