Blackholes2 Forum Message . ... Black Holes As A Source Of Dark Matter/energy? ... Would it be possible that they actually convert the physical matter and energy we're familiar with to dark matter?

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... HUBBLE UNCOVERS DUST DISK AROUND A MASSIVE BLACK HOLE . Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the jets in NGC 7052 are not perpendicular to the disk, it may indicate that the black hole and the dust disk in NGC 7052 do not have a common origin. ... NGC 7052 is located in the constellation of Vulpecula, 191 million light-years from Earth. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Bad Astro Store . ... Fun Stuff . ... It's the same with black holes. A black hole is an object with so much mass squeezed into so tight a space that the escape velocity-- the velocity you would need to be able to get away from the black hole-- is higher than the speed of light. ... Anyway, the material in this disk orbits the black hole just like planets around the Sun: the closer in you get, the faster you orbit. ... 2008 Phil Plait. ...

Observations over the last decade indicate black-holes likely resided at the heart of most if not all galaxies. The correlation between the masses of these compact nuclear sources and their host galaxy is poorly understood and likely plays an important role in the formation and evolution, of at least the most massive systems, due to AGN feedback. ... I will give a brief summary of the reverberation mapping technique and describe the important role SkyMapper photometry can play in this program. ...

BLACK NIGHT Black night is not right, I don't feel so bright, I don't care to sit tight. Maybe I'll find on the way down the line that I'm free, free to be me. Black night is a long way from home.

... NASA's Hubble Space Telescope offers a stunning unprecedented close-up view of a turbulent firestorm of starbirth along a nearly edge-on dust disk girdling Centaurus A, the nearest active galaxy to Earth. A ground-based telescopic view (upper left insert) shows that the dust lane girdles the entire elliptical galaxy. This lane has long been considered the dust remnant of a smaller spiral galaxy that merged with the large elliptical galaxy. ...
