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.)

This of interest to you, mate?
I thought this article was about obama’s head?
Careful folks...
Any time an object seems to be manipulated by another object that can’t be seen, it’s a black hole. Too bad the math shows that black holes cannot exist.
Yes, with that title this thread could get interesting.....
I thought it was about Reggie and what brought tears to obama's eyes.
Sorry everybody
It ate them.

What math is that? Common Core?
>>>I thought this article was about obamaâs head?<<<
I kinda thought it might be about something that Laz might hit.

WARNING! Do NOT Google this title!
??? Who but the completely clueless (not you, mate) still use the Goog? Why not simply click on the link and read the article referenced in the thread?
The idea of a “black hole” was first proposed by John Mitchell in 1783. He hypothesized that there might exist massive bodies so big that their “escape velocity” would be greater than the velocity of light. This is the original source of the mistake.
The mistake is this: yes, a stone thrown up from such a body could never escape: it would lose energy by losing velocity (E = 1/2 mv^2), and hence surely be brought to rest and pulled back down. But light cannot lose velocity; rather it loses energy by becoming redder (E = h nu).
If you do the math, you will discover that a light ray emitted from a massive body, no matter how massive, can never be red shifted into extinction. I have the math on my home machine; I’ll bring it in and post it.
Is that wrong?
“...a merger of two galaxies”
I’ve been through this crap. The little planets are going to get SCREWED OVER, big time.
You’re using classical physics to analyze something predicted by relativity. Not even wrong.
