  Astrocast.TV — Authority: 133
  In a paper submitted to the Monthly Notices of the Royal Astronomical Society, available online now here , astronomers from UC Berkeley discuss their computer simulations of the gas in the vicinity of massive black holes in the core of galaxies. Of note are the conclusions that black hole accretion rates and star ...

• say, how far away is that black hole?

  
  weird things — Authority: 516
  Trying to pin down the distance between our planet and a nearby black hole is a very tricky business. By virtue of being pinpoints of self-gravitating energy, black holes are usually about the size of a big city and very hard to observe directly. Their small size is also what makes it so difficult to capture a ...

• Getting a clearer view of supermassive black holes at the centres of galaxies

  
  The Plummet Onions — Authority: 122
  Most people have heard of black holes : when a big chunk of matter (like a star) no longer has sufficient internal pressure to withstand its own gravity it can collapse and suck in anything that comes past a line called its event horizon. They’re weird, freaky things, to be sure, but theory predicted them, and ...

  Universe Today — Authority: 658
  Homer Simpson would be sad: recent observations of the binary system of a black hole and its companion star have shown the retreat of the doughnut-shaped accretion disk around the black hole. This shrinking doughnut was seen in observations of the binary system GX 339-4, a system composed of a star similar in mass ...

  The fiscal projections in yesterdays PBR - just like last Aprils budget - rest on economic growth assumptions that are ludicrously optimistic.

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

  
  International Space Fellowship — Authority: 582
  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 ...

  Environmental Graffiti — Authority: 621
  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 ...
