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... |

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... |

While investigating the central regions of the Milky Way using an interferometer telescope, astronomers were able to detect traces of stellar fossils that appeared to have been produced by what could best be termed as cosmic intruders. These objects most certainly did not originate inside the galaxy, astronomers say.... |

For many years, astronomers have believed that elliptical galaxies formed through the collision of two or more, smaller spiral galaxies during a catastrophic event. Experts now propose an alternative mechanism that may have yielded the same result, and which does not require collisions.Ellipticals are galaxies that c... |

In a new study they conducted recently, astronomers were surprised to discover that supermassive black holes can exist at the core of minute, dwarf galaxies as well, and not just at the center of very large ones, such as the Milky Way.This discovery brings an old, chicken-and-egg-type of question back into the spotli... |

The Milky Way is only one structure in a sea of galaxies permeating the Universe. Astronomers can peer through it at various wavelengths in order to look deep in the Cosmos, back to the time when it was only a few millions of years old.

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... |

Don't ask me when the end of the world will come, I can't tell you, but one thing is for certain: a black hole could possibly trigger one. Especially taking into consideration the fact that about 30 percent of the total black holes population in the universe is thought to wander alone through space. Add the... |

Spiral galaxies such as our Milky Way are believed to unwind their arms inwards in the spinning directions; however, it seems that not only this is not always the case, but some can also present arms unwinding towards inner and outer regions regardless of the spinning direction of the galactic disk. The original pape... |

An astronomer once estimated that, if someone counted every grain of sand existing on all the beaches on Earth, it would not be enough to equal the enormous number of galaxies observed in the visible universe. But even with such a high number of galaxies visible on the sky, young galaxies that can reveal how the spir... |
