Astronomers using a NASA telescope managed to identify a pair of gamma-ray bubbles being produced at the center of our galaxy, the Milky Way. Early analyses of the latest data seem to indicate that the structures are being produced by the supermassive black hole that occupies the galactic core. The twin structures we... |

Scientists have recently determined that its possible for white dwarfs to grow by accreting medium-sized celestial bodies such as protoplanets called planetesimals. These space bodies can even contain water in concentrated forms, astronomers say.The discovery was made as experts were investigating the ways in which e... |

Investigators announce that AX Persei, which is a symbiotic variable star system, shows signs of increased activity, which means that it could be on its way towards a new eruption. This star has been under monitoring for years, because it goes through cycles of calm periods and times of massive eruptions, and as... |

A team of astronomers has been able to demonstrate for the first time that young galaxies can accumulate nearby cosmic gas in order to fuel their growth over time. This is done by using cool hydrogen gas to produce new, blue stars in specialized regions called stellar nurseries. There areas can be found throughout ga... |

Given the high number of exoplanets discovered over the past few years, it's worth taking a look at the main methods through which such celestial bodies form and develop. Exoplanets, or extrasolar planets, is the name given to celestial bodies that orbit stars other than the Sun. These objects can exist tens to ... |

According to a new complex computer simulation, it would appear that the earliest black holes that where formed after the Big Bang were in fact a lot smaller than the giants they are today. Also, the simulation revealed that older theories, which held that the formations accumulated mass quickly and gobbled up matter... |

The Messier 87 galaxy, known among astronomers as M87, Virgo A, or NGC 4486, is an elliptical galaxy of massive proportions, located in the Virgo Cluster, some 55 million light-years away from Earth. For more than seven years, the Hubble Space Telescope has been following the evolution of the supermassive black hole ... |

While astronomers have a fairly decent understanding of how stars pop into existence, the underlying processes that trigger their formation in the first place are still clouded in mystery. Actually, they are clouded in cosmic dust and gases, which are also the basis for the new stars. Devising a way of penetrating th... |

After processing new readings gathered from various space- and Earth-based telescopes and observatories, astronomers now say that the energy that a black hole can unleash is sufficient to wipe out the galaxies around them, and send “death waves” for millions of light-years around the blast zone. All black... |

For a long time, astronomers studying the formation of massive stars have been puzzled at how the giant celestial bodies, some 120 times larger than our Sun, can expand without “chasing away” the dust and gas clouds that feed their growth. According to a new theory, this relative stability can be explaine... |

The Large Hadron Collider is rapidly approaching completion and should become operational by the end of the year. It will become the biggest particle collider ever built, probably powerful enough to create even microscopic black holes. It has been suggested on a number of occasions, despite CERN's reassurance, t... |

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 ... |

Recent observations made by XMM-Newton reveal a strange formation process in baby star, defying astronomers' expectations. They show how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays.So far, the generally accepted process of star formation involved dense parts of mole... |

A recently developed method has successfully been applied for weighing a black hole named Cygnus X-1, located in the constellation Cygnus (the Swan) approximately 10 000 light years away in our Galaxy, the Milky Way.A black hole is an object with a gravitational field so powerful that a region of space becomes cut o... |
