KISSIMMEE, FLORIDA--Most, if not all, galaxies have supermassive black holes at their centers surrounded by dense clouds of stars. Now, researchers have found one that seems to have lost almost its entire entourage. The team, which reported its find here today at the annual meeting of the American Astronomical Society, says it doesn't know what stripped the stars away. But it has put forward a tantalizing possibility: The object could be an extremely rare medium-sized black hole, which theorists have predicted but observers have never seen.
The unusual black hole sits about 1 billion light-years from Earth in SDSS J1126+2944, a merger of two galaxies. Julie Comerford, an astronomer at the University of Colorado, Boulder, and colleagues first spotted it last year, "a small beauty mark off to one side" of the agglomeration, which hosts another giant black hole at its center," she says. The two black holes, detected by NASA's Chandra X-ray Observatory, are separated by 7000 light-years, but the larger one seems to have 500 times as many stars around it compared with the smaller one.
It's possible, Comerford says, that somehow during the turmoil of the merger millions of years ago, gravity could have stripped the smaller black hole of its stars. But perhaps it just started out with fewer stars because it's a different sort of black hole. (The Chandra observations don't reveal the objects' masses.)

Thanks! bfl.
Should be alright if you have “safe search” on. Otherwise, get the kids out of the room real fast!
Looks pretty tame to me ... the mystery of the naked black hole.
But I bet you could liven up the SERP a bit simply by adding the word porn to the query ... dare you!
No need to add any additional words.
I didn't dare try it with "safe search" off.
__________________________________________________________________________________
I would have to make a deliberate choice to do that (similar to making a deliberate choice to add the word "porn" to the Google query).
BTW, I never turn on safe search. If it's unsafe, I want to know. Adding "porn" to a query is simply giving the search engine a hint as to what I want. That's the way I like it — me in control!
Just tried the query. With Safesearch on, the results are unsatisfactory: a worthless warning page. With Safesearch off, the results are also unsatisfactory: gratuitous porn results (preceded by a lawyer screen — I have nothing but contempt for those) intermixed with legitimate results.
I will stick with the GOOG and forget that Yahoo ever had or has a search engine.
I’ve been using Yahoo Search for years. It’s worked pretty good for me. Can’t stand anything involving Google. They’re way too intrusive, linking your PC to all sorts of other crap of theirs.
Since they can’t be observed, They are conjectures.
So many punch lines, so little time...
this all jes plain RACESS!!!
We can find black holes by their Hawking radiation and their imense gravity. NASA just found another one yesterday only 100 billion light years away. Scientists have also proven the existence of black holes by their lensing effect as predicted by Einstein’s theory.
Could a black hole be a means of escape from our universe into the outside?
Thanks Utilizer.
I believe you need to settle on a definition of what exactly you mean by “outside” before you can attain an answer to that particular question.
Anytime, mate!
Well, if the experts say the universe is expanding, there has to be something out there beyond the edge that it is expanding in to.............But what do I know.....LOL!
The behavior of light near a massive bosy was indeed predicted by Einstein. Arthur Eddington tested the prediction during the eclipse of 1919, and claimed Einstein was right.
It was later discovered that the had thrown away the 85% of the observations that refuted Einstein, and kept the 15% that could be fudged to confirm him. This has been called “the biggest hoax in 20th century science”.
Almost every other prediction by Einstein also proved false. The constancy of the speed of light was refuted by the experiment of Michaelson and Gale, by the Sagnac experiment, and by the Haefele-Keating experiment.
