    It gushes out x-rays which is what a fission star would do and Hawking theorized black holes would as well.

    Indeed, this is really fascinating. I happened to read the same article over at TG Daily just before seeing your post.

    I just wish I could overclock my PC to 20 million mph! :laugh:

    Ordinary black hole discovered 12m l.y. away!

    Fascinating!

    But it's really hard to detect black holes because they don't emit light but when matter is dragged into a black hole it heats up in the process and emits X-Rays.

    [​IMG]

    The yellow arrow identifies the position of the black hole transient inside Centaurus A. The location of the object is coincident with gigantic dust lanes that obscure visible and X-ray light from large regions of Centaurus A. Other interesting X-ray features include the central active nucleus, a powerful jet and a large lobe that covers most of the lower-right of the image. There is also a lot of hot gas. In the image, red indicates low energy, green represents medium energy, and blue represents high energy light.

    Keep the black hole stuff coming, this was fascinating! :toast:

    12 million light years? OMG OMG - that's practically next door.

    We're doomed - Doomed I say - Ahhhhhhhh!!!! ;) :cool:

    Another great discovery:

    [​IMG]

    You can spot a lot of galaxies there and intergalactic gas. Optical emission reveals the presence of dark matter through the effect of gravitational lensing (blue). ;)

    Wow, that's quite some brightening there. I'd love to be able to see a proper image of this thing up close as it happens. It would be fascinating. Interestingly, it's not just a tiny spec of a dot, but has an actual size and the other stars look bigger - our telescopes are getting better.

    Drone, keep these posts coming! :toast:

    Look at the speed of that thing ....

    Gas cloud will collide with our galaxy's black hole [known as Sagittarius A* (or Sgr A*)] in 2013. Go, check your calendars. This is the first time ever.

    Yeah it seems our galaxy doesn't like guests lol. That gas cloud is doomed, its days are numbered.
    That's how Sgr A* welcomes guests.

    Can't wait to see that!

    Seems to me common sense dictates, once u get enough mass you wouldn't need an explosion. Just a coalescing of that mass, until it becomes so large it is a blackhole.. Idk why you would need some kind of massive explosion.. Typical science jumping to conclusions...lol..

    Hunderds of black holes!!!!

    A bunch of black holes has been found! Scientists were using the technique VLBI [Very Long Baseline Interferometry]. Their team made measurements at different radio wavelengths over a period of 17 years. :eek:

    [​IMG]

    It's obvious: jets created by black holes are sending out radio signals.

    Jets blow the cover.

    What a leecher! Suckah!

    That galaxy is pretty busy. Stars, supernovae, binary systems, rare types of black holes (microblazars). :eek:

    It seems that galaxies like Arp 220 can contain very large numbers of microblazars. :cool:

    I thought I was interested in black holes, but damn Drone, you're heavily into them. :cool:

    Great find. Hundreds of black holes, Jesus H f* Christ... :eek:

    Newly found black hole.

    [​IMG]

    This is the first discovered intermediate mass black hole. It was discovered by accident and they have no clue how it has come to exist.

    Peekaboo, I see you. It's about 90000 times heavier than our sun or something like that.

    Dark matter detector

    I thought this was probably better off in this thread, rather than a new one:

    A group of physicists and biologists are planning a DNA-based dark matter detector.
    The plan is to detect the 'dark matter headwind' coming from the direction of the constellation of Cygnus (that is the direction that the Sun is travelling in, in its orbit around the galactic center).

    Here's a beautiful animation showing the awakening of a distant galaxy's dormant black hole as it shredded and gobbled up a passing star. The galaxy is so far away that light from the event had to travel 3.9 billion years before reaching Earth. So far, so violent, so beautiful *drools*



    That's a sexy X-Ray shower there.

    Mesmerizing process. These QPOs send us information from the very brim of the black hole, which is where the effects of relativity become most extreme.

    Umm ... can you imagine that?

    [​IMG]

    Now that's a lot of them!

    http://phys.org/news/2012-08-wise-survey-uncovers-millions-black.html

    WISE scanned the whole sky twice in infrared light, completing its survey in early 2011. And that's not all... Astronomers have identified about 1000 hot DOGs (dust-obscured galaxies). That's one of the main goals of their mission.

    That darn cosmic dust *shakes fist* ... but anyway this all is so amazing incredible and unbelievable.

    Drone, this is especially for you. :cool:

    The Strangest Black Holes in the Universe

    So, just how immense is the gravity of the first black hole with an event horizon five times the size of the orbit of Pluto! I can't even begin to comprehend it.
