• Astronomy Question of the Week: How is a black hole discovered?

  
  International Space Fellowship — Authority: 609
  Black holes are astrophysical objects with an almost unbelievably high mass per unit volume. They are so heavy that they are able to powerfully warp the space around them. Within a certain distance from the black hole – the ‘event horizon’ – this warping of space is so strong that absolutely no light or any ...

• Gazing into the Center of the Milky Way

  
  Environmental Graffiti — Authority: 651
  Not too many years ago, astronomers despaired over whether they would ever get a clear, sharp, informative picture of the galactic center. The giant clouds of dense gas that dominate the center of the Milky Way seemed to be an impenetrable barrier. Nonetheless, persistence paid off and a few years... This is just a ...

• Central Black Holes or their Galaxies, Which Came First

  
  Astrocast.TV — Authority: 132
  Scientists from the European Southern Observatory (ESO) announced earlier this week that they have evidence which leads them to believe that black holes may have led to the formation of the galaxies within which they reside. You can learn more about this by reading the ESO announcement here . Or read the scientific ...

• Far-Off Quasar Could Be the Spark That Ignites a Galaxy

  
  80beats — Authority: 642
  Which came first: A galaxy or the supermassive black hole at its center? Thanks to a misfit quasar, astronomers have some new clues. Quasars are particular kinds of black holes that release incredibly intense jets of energy,  and scientists spied this one five billion light-years away. To their surprise, the ...

• Quasar Caught Building Future Home Galaxy

  
  Universe Today — Authority: 648
  The birth of galaxies is quite a complicated affair, and little is known about whether the supermassive black holes at the center of most galaxies formed first, or if the matter in the galaxy accreted first, and formed the black hole later. Observations of the quasar HE0450-2958, which is situated outside of ...

• Black holes can “build” their own host galaxies

  
  Thaindian News — Authority: 731
  Munich, December 1 (ANI): Recent observations by astronomers have indicated that black holes may be “building” their own host galaxies.This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars.“The ‘chicken and egg’ question of ...

  Ted Bunn's Blog — Authority: 410
   Who knew that, a dozen years after I wrote something trying to explain a bit about black holes, people would still be reading it?  I get questions from time to time from readers, and I’m happy to try to answer them.  As long as I’m writing answers anyway, I’ll go ahead and post them here in case anyone ...

• Massive “Dark Halo” Discovered Beyond Edge of the Milky Way

  
  Heidi-Lore's Musings — Authority: 128
  The biggest things in the universe just got bigger – or rather, they’ve always been bigger and we somehow missed it up to now.  Supercomputer simulations of galactic core black holes indicate that instead of being a mere two billion times the mass of the sun, so insignificant you’d surely lose them if you ...

• Naked Black Hole Builds Future Galactic Dream Home

  
  Wired Science — Authority: 748
  Astronomers have captured a distant black hole creating the galaxy that will eventually become its home. By sending a jet of gas and highly energetic particles into a neighboring galaxy, the black hole has touched off star formation at a rate 100 times the galactic average. “Our study suggests that supermassive ...

  Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be “building” their own host galaxy. This could be the long-sought ...

  Once upon a time, we took a look at why creating black holes in particle colliders and using them to generate energy for our power grids was fraught with problems . However, if at sometime in the future we could scale up our lasers and use them to create a black hole with a mass energy equivalent of a million tons, ...

  Revelations From An Unwashed Brain — Authority: 596
  Science is a funny thing. Once we think  a handle on a concept has been had, the new information comes in, and all bets are off because the theory doesn’t fit the facts any longer. Isaac Newton in the 1600s, thought he had explained the concepts of many things adequately, and with the invention of calculus, ...
