Some gas tendrils between two galaxies indicate that a high-speed collision of the celestial bodies once took place. Scientists look up to this as a possible clue to the reason so many of the galaxies are unable to form new stars.One of the two is the spiral galaxy NGC 4438 situated about 50 million light years away ... |

Since the distance between space's bodies is so enormous, astronomers have very hard times counting and measuring all the newly-emerging stars. That's why the H-alpha characteristic signal emitted by the new stars comes as a blessing for those who detect them by telescope. The amount of such rays emitted fr... |

The mysterious force that drives the patches of matter at incredible speeds and in uniform directions through space, which can't be explained by comparison to any known gravitational force, and which may also exist outside of the observable universe, was called "dark flow."If you think you already know all there... |

Late in the evening of September 19th, people living or traveling north of a line crossing North America will be able to observe the Pleiades star cluster being hidden by our moon. Although the term occultation – which is derived from the Latin "occultatio," meaning hiding – might be new to many of ... |

LBG-2377 is a galaxy proto-cluster located 11.4 billion light years away from Earth - the most distant galaxies ever observed. In fact, these galaxies are so far away from us, that they appear as they looked when they were in the first days of their lives. Previously, the most distant such galaxy proto-cluster was lo... |

Earthquakes are some of the nature's most destructive forces and the main problem about them is that we can't really predict when and where they are going to occur next. Of course, there are fault lines and areas where tectonic activity has been recorded for hundreds of years, but we can't say for sur... |

Black holes are space objects which have an immense gravitational field that cuts off a region of space from the rest of the universe, trapping all matter and radiation that enters that region. They are objects with a gravitational field so powerful that a region of space becomes cut off from the rest of the univers... |

Astronomers claim to have captured images showing the very first light that appeared in the Universe. Using NASA's Spitzer Space Telescope and a new digital technique, they took a picture of the sky and saw light originating from the first stars that appeared in the Universe, more than 13 billion light-years aw... |

The Hubble Space Telescope did it again. It captured a truly amazing picture of what looks like a cosmic display of fireworks, in the dwarf galaxy NGC 4449. A massive starburst shows a wonderful light show in the galaxy and astronomers think it was caused by interaction or merger with a smaller companion.NGC 4449 is... |

Open star clusters are among the most important tools for the study of stellar and galactic evolution. The Pleiades are one of these clusters, a young and bright one, dominated by hot blue stars, which have formed within the last 100 million years. The Pleiades' high visibility in the night sky has guaranteed i... |

Black holes have been known to exist in several environments, like in the center of most galaxies, including our own Milky Way, or created by the collapse of individual stars, and even produced after the collision of two galaxies. So far, little was known about another, stranger type of black hole, that lurks in the ... |

New observations of a globular star cluster G1 - a large, bright ball of light in the center of the photograph consisting of at least 300,000 old stars - located in the Andromeda Galaxy (M31), show that it most probably has a midweight black hole at its center. This new find supports the theory that supermassive bla... |

A dwarf galaxy is a small galaxy composed of up to several billion stars, a small number compared to our own Milky Way's 200-400 billion stars. These small galaxies frequently orbit around larger galaxies, such as the Milky Way, the Andromeda Galaxy and the Triangulum Galaxy.NASA's Spitzer Space Telescope ... |

It seems physicists around the world are predicting a grim future for our heirs who will want to learn more about space.

Although astronomers believe that dark matter accounts for 25% of the total mass of the Universe, if one asks them how it looks like, he/she will only get a straight face. So far, it does not emit or reflect enough electromagnetic radiation to be observed directly, so its presence can only be inferred from gravitat... |

German astronomers have discovered a rich globular cluster of about 100,000 stars in the center of our Galaxy, placed 30,000 light-years away from the solar system and 10,000 light-years away from the Galactic Centre. Globular star clusters are groups of stars with similar ages, composition and distances representing... |
