Well, I don't know the cosmic geography of the area around the Milky Way but if there is a black hole in the middle, that's pretty scary, but they think it's dormant
And our sun is a young star so .. yea

WASHINGTON (Reuters) - A giant black hole displaying horrifying table manners has been caught in the act of guzzling a star in a galaxy 4 billion light-years away, scientists using an orbiting NASA telescope said on Tuesday. For the past two years, scientists have monitored the dramatic events as the star, residing in a galaxy in the Bootes constellation, was ripped apart by the black hole. Scientists used NASA's Galaxy Evolution Explorer, an orbiting telescope sensitive to two bands of ultraviolet wave lengths, to detect an ultraviolet flare coming from the center of a remote elliptical galaxy. "This ultraviolet flare was from a star literally being ripped apart and swallowed by the black hole," Suvi Gezari of the California Institute of Technology in Pasadena and lead author of the paper describing the findings in Astrophysical Journal Letters, said in an interview. "This is the first time that we've actually been able to monitor the flare of radiation from such an event in detail. Only once every 10,000 years will a star pass close enough to a (galaxy's) central black hole to be ripped apart and swallowed in this manner," Gezari said. The scientists hope the findings will give them a better understanding of black holes, objects whose gravity is so powerful even light cannot escape. It is believed that super-massive black holes are located at the core of every galaxy. For example, Gezari said, the Milky Way galaxy in which our solar system resides has a dormant super-massive black hole at its center. Scientists said in this case the unfortunate star strayed a bit too close to the black hole deep inside the galaxy, and was mutilated by the force of its gravity. They believe that parts of the star swirled around and then plunged into the black hole, which sent out the bright ultraviolet flare that the satellite detected. Scientists continue to use the telescope to observe the ultraviolet light as it fades while the black hole snacks on the final table scraps from the devoured star. "We looked at the galaxy in 2003 and there was no ultraviolet light coming from the galaxy at all," Gezari said. "And then in 2004, we suddenly saw this very bright source." "The only way to explain such a luminous ultraviolet flare is if the black hole swallowed a star," Gezari said. Caltech leads the Galaxy Evolution Explorer mission and is responsible for science operations and data analysis, while NASA's Jet Propulsion Laboratory manages the mission and built the instrument. The scientists also used data from NASA's Chandra X-ray Observatory, the Canada France Hawaii Telescope in Hawaii and the Keck Telescope in Hawaii. |

That is pretty cool.. But if you think about it.. they are actully viewing something that took place BILLIONS of years ago XD It is cool to know ther is another space junkie on RSBandB besides myself = P |

Rather spooky that a black hole could just suck us all up, especially as they haven't got a clue how many there are. |

There's a black hole at the centre of every galaxy. All the stars in the galaxy orbit (while getting closer each rotation) the black hole, just like the planets orbit the stars. |

our sun is too small to turn into a black hole. it's will just explode and become a nebula and after a few thousand years it will become a new star |

If by thousands, you mean billions. |

At the moment it's too small, but it will swell up eventually. Though I doubt anyone's certain how big they get. |

Yeah, pretty much billions upon billions of years trek. |
