A team of scientists from the National Radio Astronomy Observatory (NRAO) believe it may have found a new explanation for the peculiar, cloud-like structures that hover above the plane of our galaxy. Astronomers and astrophysicists have been trying to make sense of these formations for many years, and the team now pr... |

Scientists at the American space agency say that they were finally able to answer a decades-old astronomical question. For years, astrophysicists have been trying to explain why a small portion of all black holes – no more than 1 percent – appear to emit vast amounts of energy at certain times. The behavi... |

Though researchers don't have unlimited amounts of knowledge on black holes, they are not completely in the dark either. As such, they were able to figure out that two nearby black holes, of the variety that exists at the center of massive galaxies, were not behaving as they were supposed to. The group behind th... |

Supernova explosions are generally accepted to be among the most violent phenomena taking place in the Universe. They take place when massive stars reach the end of their burning cycle, and exhaust their hydrogen supply. As they explode, they produce so much energy that their light signature briefly outshines that of... |

Scientists from the University of California in Berkeley (UCB) announce that they were recently able to image the collision between the Sun and a comet in full 3D. They say that this is the first instance they know of in which something like this has been accomplished, and add that the observations are bound to yield... |

One of the things that has remained the same about exoplanetary studies is the fact that astronomers always assume that a planet's orbit has remained the same for a long time. In most cases, this really happened, but in other instance it's far from it, scientists say. Recent studies on the influence gas gia... |

In spite of having been launched only a few months ago, the WISE Space Telescope is already proving its worth in the eye of astronomers. Its goal is to survey the entire Universe one and a half times over, but in the meantime, it's providing some spectacular vistas of nebulae, stars, near-Earth objects (NEO), as... |

Astronomical knowledge has advanced over the years to a point where experts can definitely say that exoplanets can also form around massive stars. The process was initially thought to only be possible around Sun-like types, but that has since been proven wrong. While searching for possibly inhabitable worlds close to... |

Astronomers have recently determined that some of the supernova explosions we see in the night skies are in fact triggered by stars known as white dwarfs merging in a violent, cataclysmic event. The findings can help explain why some of the massive blasts that follow, which are so precise that they are currently used... |

Astronomers announce the discovery of a new exoplanet, which appears to be one of the smallest such celestial objects ever identified. According to experts, it is only four times larger than the Earth, which makes it the second smallest exoplanet in the known Universe. For the new discovery, a research group used the... |

In the early days of the solar system, when the Sun was still young, and the planets were racing and colliding with each other all over the place, the Earth avoided a cruel faith. According to astronomers, there was a very high possibility for the planet to fall into the new star, and, in fact, this is what should ha... |

One of the most Earth-like planets ever discovered, called CoRoT-7b, is most likely the only object known to be part of a category of celestial bodies called evaporated remnant cores. According to astronomers who have studied the exoplanet, its rocky nature is very peculiar given the distance it orbits from its paren... |

Scientists confirmed the existence of the exoplanet CoRoT-7b in October, 2009. The body was found orbiting a nearby star, which is located about 480 light-years away. Measurements at the time determined that the structure had to be rocky, with a solid surface, but new data seem to indicate that the planet may actuall... |

Astrophysicists determined some time ago that the Milky Way, and probably most other galaxies too, was surrounded by a halo of dark matter. The stuff cannot be detected by conventional means, and neither analyzed directly, so its existence can only be inferred from the effects it exerts on stars, galaxies, and other,... |

For many years, astronomers have been looking for exoplanets around Sun-like stars, as they believe that these celestial bodies have the highest chances of harboring planets similar to our own. However, in recent studies, it has been demonstrated that planetary formation is a direct, natural byproduct of stellar form... |

In certain massive galaxies, including our own Milky Ways, the large black holes at their cores appear to be starving. That is to say, they no longer accumulate new matter in their accretion disks, from where they pass it on through the event horizon. In a new development, researchers using the NASA Chandra X-ray Obs... |

The bright star Epsilon Auriga has been an object of fascination for astronomers for nearly 200 years, mostly because of its peculiar, yet-undeciphered nature. The star, which is visible with the naked eye, appears to become brighter, and then dimmer, as the years pass, and early scientists had no idea as to why that... |

Scientists have known for a long time that many types of stars can form planetary systems around themselves. Mostly, this is done from debris fields left behind after the stars themselves are formed, which are called protoplanetary disks. Unfortunately, it is also well known that the Milky Way is not exactly the most... |

The famous Hubble Space Telescope, with its newly installed, advanced scientific components, is now able to look extremely far back into the history of the early Universe, at a time when everything around us was just a fraction of its current age. Such a deep look was taken recently, when the telescope peeked at a ti... |

Albert Einstein's theory on general relativity holds that the moment that marked the beginning of the Universe also determined the conception of gravitational waves. These are fluctuations that develop in the curvature of space and time, but, until now, they have proven to be extremely difficult to detect. One p... |

Astronomers propose a new theory related to the core of very large stars. They say that, when the inner parts of such a celestial body become too hot, they start forming matter-antimatter pairs. Naturally, when this happens, the basic laws of physics dictate that a violent annihilation between the two occurs, and thi... |

Astrophysicists have known for a long time that at the core of every massive galaxy lies a very large black hole that feeds on the matter there. The black holes are known to create features named accretion disks, which are heated to millions of degrees and represent the final resting place of regular matter before it... |

Being the massive galaxy that it is, the Milky Way contains a little bit of everything. This includes highly explosive white dwarf stars that explode periodically at relatively stable intervals. Such a celestial body, which is long overdue for its next powerful eruption, lies closer to our planet than astronomers fir... |
