[quote][color=#000000][font=Verdana, Arial, sans-serif][size=3]Undergraduate student Marianne Heida of the University of Utrecht has found what appears to be a supermassive black hole leaving its home galaxy at high speed. As part of an international team of astronomers, this extraordinary discovery appears in a paper in the journal Monthly Notices of the Royal Astronomical Society.[/size][/font][/color]

[color=#000000][font=Verdana, Arial, sans-serif][size=3]
For her final year project, Marianne worked at the SRON Netherlands Institute for Space Research, used the Chandra Source Catalog (made using the orbiting Chandra X-ray Observatory) to compare hundreds of thousands of sources of X-rays with the positions of millions of galaxies. Normally each galaxy contains a supermassive black hole at its centre. The material that falls into black holes heats up dramatically on its final journey and often means that black holes are strong X-ray sources.[/size][/font][/color]

X-rays are also able to penetrate the dust and gas that obscures the centre of a galaxy, giving astronomers a clear view of the region around the black hole, with the bright source appearing as a starlike point. Looking at one galaxy in the Catalog, Marianne noticed that the point of light was offset from the centre and yet was so bright that it could well be associated with a supermassive black hole.[/size][/font][/color]

The black hole appears to be in the process of being expelled from its galaxy at high speed. Given that these objects can have masses equivalent to 1 billion Suns, it takes a special set of conditions to cause this to happen.[/size][/font][/color]

Does anyone else think the idea of these things being thrown around at massive speed is slightly terrifying? :p

Oh God, I had the same thought whilst reading that.

I'm quite nervous imagining such a sucker being flung at us and we can't do shi* about it.

I kinda find the idea of a black hole meeting another one, handshaking and then flying off together kinda cute though. :p
*Angry Birds <puuuuui> sound* :D

What the article doesn't say is that that black hole is going to smack us in the face in 9 days! :cry: :o :shiftyninja: :rofl:

1) really cool - probably a galaxy with >1 supermassive black hole. This was the smallest & got voted off the island.

2) this thread really needs to be moved to the Science forum.

Even black holes cannot prevent themselves from being expelled from their class.

I didn't realise there was a science forum (although I'm sure I've seen it before), but I agree!

Everything moves even space, didn't you pay attention when Spock helped Scotty figure out the transwarp beaming equation.
