Crazy old black hole's X-ray ultra-belch makes galaxy blush
A powerful blast of X-rays - equivalent to the energy emitted by a MILLION Suns - has been fired out of a black hole in the spiral galaxy M83, lighting up the space around it.

Very good
If we could approach a black hole type thingy how much acceleration is possible?
Re: Very good
I need your banking details Norman, you owe me a new keyboard.
I'm ashamed to ask this...
I must have missed this day at school - black holes are 'black' because electromagnetic waves are captured completely by them. Where do the x-rays come from? Just outside the black hole?
Re: I'm ashamed to ask this...
Yep, as matter is spun furiously in orbit around the event horizon, due to the blackhole's intense gravity, it becomes energized, emitting x-rays.
Kind of a naturally occurring particle accelerator.
Re: Life in outer space?
Not in the immediate vicinity of this exuberant couple at least...
Actually, this explain a bit why we're in a cozy outer arm of the galaxy instead of in a more central place... In the galactic center, a planet would be constantly sterilized due to the various partying neighbours.
Is «MILLION» more than, less than, or equal to
«million» ? Or did the Reg editor simply get his finger stuck on the caps-lock key ?...
