According to the results of a new scientific study, it would appear that the Milky Way's spiral shape was not a direct product of its evolutionary path, but rather a result of collisions between our galaxy and two other dwarf galaxies. The events took place within the last 2 billion years.

By analyzing the chemical signature of molecules such as carbon monoxide, experts at the Harvard-Smithsonian Center for Astrophysics (CfA) were recently able to confirm the existence of a new spiral arm in our galaxy, the Milky Way.The arm is in fact an extension, located at the far end of the Scutum-Centaurus Arm. T... |

One of the two theories widely proposed for explaining the formation of spiral galaxies may be wrong, either in part or altogether. The conclusion belongs to a new research paper, which analyzed both points of view objectively. Though hundreds of billions of spiral galaxies permeate the Universe, the process underlyi... |

Experts now propose that our galaxy features 3 galactic arms, rather than 2 proposed until now. The discovery also implies that the overall shape of the Milky Way may be a bit different than calculated based on the old data. The fact that Milky Way is a spiral galaxy has been proposed – and widely accepted &nda... |

A researcher in the United Kingdom is now proposing a new model for explaining how the arms of spiral galaxies are moving around the central bulge. The new view is in direct conflict with existing, widely-accepted theories explaining the same phenomenon.The proposal is also seeking to explain how spiral arms evolved ... |

Astronomers were recently able to catch a new view of a beautiful galaxy located relatively close to Earth, in the direction of the Sculptor Group. The object is called NGC 247, and it is inclined at a steep angle as viewed from our vantage point. The image was collected by experts with the European Southern Observat... |

If you are interested in looking for star clusters, then the times when the Moon is out of the evening skies, such as the current ones, are the best for observations. Using a pair of good binoculars, amateur astronomers can easily detect several famous structures of this class.
Some interesting star clusters can ... |

Astronomers show in a new galactic map that the Milky Way may have arms that are straight rather than curved, which may give it a unique, square-looking appearance. Determining the exact shape of the Milky Way is an extremely complex task, given that we cannot see it from the outside like we see for example our neigh... |

Following the first studies of our galaxy, it was determined that it belonged to the spiral-arm class, and that it had two such formations orbiting its core. Work that was done later on disproved that hypothesis, and revealed that the Milky Way in fact sported four arms. The latter remained the norm for many years, b... |

Ever since astronomers started differentiating between spiral and elliptical galaxies, they have wondered what precisely makes some galaxies develop their trademark arms, while others remain without them. Our own galaxy, the Milky Way, is a spiral one, featuring two, or, according to new studies, four arms. A team of... |

Since the days of radio observations, astronomers believed that the Milky Way galaxy, in which our solar system is located, has four spiral arms wrapped around the central galactic nucleus. But radio observations are only able to detect concentrations of gas in the galaxy and what previously appeared to be two spiral... |

Weighing supermassive black holes located in the center of galactic nuclei is more like looking through a solid brick wall, since matter in quantities of billions of times the mass of the Sun may stand in the way. Nonetheless, we are capable today to approximate the masses of supermassive black holes just by observin... |
