In a new study of the M31 galaxy, our closest galactic neighbor from the Andromeda Constellation, the American space agency's Swift satellite managed to snap the most complex and detailed image of its ultraviolet sources. Experts say that some 20,000 of them are visible in the new, high-resolution picture, and t... |

With more than 300 exoplanets discovered thus far inside the Milky Way, this field of astronomical research is expanding at an exponential rate. Despite the fact that a single extra-solar planet has thus far been identified directly, experts know that the other hundreds exist because they can detect their influence o... |

According to a recent infrared study of the Triangulum Galaxy, also known as M33, our “neighbor” appears to be larger than its observations in visible light have suggested until now. The new measurements have been conducted with NASA's Spitzer Space Telescope, which specializes in resolving infrared ... |

Following the latest research results, astronomers concluded, during the 213th meeting of the American Astronomical Society, that our galaxy, the Milky Way, is about 50 percent heavier than previously thought, and that the speed with which it spins is also much greater than first calculated. The scientists came to th... |

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... |

It is a well known fact that galaxies can form new stars as they move through the space to join other galaxies in dense galaxy clusters which are pulled together by the powerful gravitational forces. Nevertheless, most of them tend to follow the gas filaments of dark matter that stretch between the galaxies. As they ... |

Believe it or not, most of the stars and cosmic objects in the visible universe are actually impossible to observe with the naked eye. Only a handful of galaxies and star clusters in the near vicinity of our galaxy can be spotted without the help of optical tools. More than 99 percent of the stars viewed on the nigh... |

The full moon lunar phase has passed, thus it's time to go back to watching the night sky, to observe some of the most amazing objects in the universe. The Andromeda galaxy, or M31 as it is also known, the closest galaxy to our Milky Way, will pass directly over our heads this week, every day between 7:30 and 8 ... |

It seems that the Andromeda constellation is full of surprises. It contains the Andromeda Galaxy and also the brightest star, Alpha Andromedae, or Alpheratz. Andromeda Galaxy and the Milky Way are approaching each other at a speed of 100 to 140 kilometers per second, but until and if they collide, astronomers are se... |

Astronomers discovered a new dwarf galaxy formed in a region of space outside our system, which is falling into our "Local Group." It's the first time when such an event has been recorded and it's considered a vital clue on the formation processes of galaxies.The Local Group is the group of galaxies that ... |

Most astronomers believe that sometime in the distant future, our galaxy, the Milky Way, and Andromeda, the closest galaxy, will collide in a massive cosmic clash. However, they can's still accurately predict whether this will occur in 2, 5 or 10 billion years.If the descendants of Homo sapiens will still inhabi... |
