[QUOTE=B1N4RY!;25984603]A telescope powered by Fermi? [img_thumb]http://www.hardwaresphere.com/wp-content/uploads/2010/03/nvidia-fermi-geforce-gtx-480-graphic-card.jpg[/img_thumb] ???[/QUOTE] this is what i thought at first
Space is so very pretty.
[QUOTE=Haxxer;25982219]This was also known long ago, if I remembered it right. Supermassive black holes shoot out giant gas streams out from them as stuff rotate around it, like this: [img_thumb]http://www.dailygalaxy.com/photos/uncategorized/2009/01/08/supermassive_black_hole_2.jpg[/img_thumb] You need a source for the radiation, it can't just appear thousands of light years from the galactic centre. Therefore the source of the radiation would be those gas streams. So it wouldn't surprise me if it shoots out shitloads of radioation[/QUOTE]
[QUOTE=Pr0vologne;25988458]As soon as I read the thread title I immediately thought of [img_thumb]http://wireninja.com/wp-content/uploads/2010/06/MassEffect_Reference.png[/img_thumb] But this is also a fascinating find.[/QUOTE] It's obviously the Reapers coming from deep space to kick Shepard's ass and talk in cheesy lines.
Galactic core? Obviously Reapers in coalition with the Collectors. :downs:
When I read the title I immediately thought of this: [img]http://www.co-optimus.com/images/upload/image/2009/halo-ring.jpg[/img]
Hope it's not the collectors, or Reapers.. Where is Shepard when you need him?
[QUOTE=Thaard;25991967]Hope it's not the collectors, or Reapers.. Where is Shepard when you need him?[/QUOTE] 144 years in a future that wont happen. I guess that means we're screwed.
So I'll bump with some content. Here's the thing itself. [img_thumb]http://apod.nasa.gov/apod/image/1011/bubble_fermi_big.jpg[/img_thumb] [url]http://apod.nasa.gov/apod/ap101110.html[/url]
Nothing terrificly surprising, but interesting none the less.
How can it get pictures of our galaxy like that if the telescope is orbiting the planet? Rate me dumb if you want but I never understood how NASA got those kinds of images.
[QUOTE=TBleader;25994966]How can it get pictures of our galaxy like that if the telescope is orbiting the planet? Rate me dumb if you want but I never understood how NASA got those kinds of images.[/QUOTE] The picture in the OP is just a nice diagram. It's currently impossible to get a picture of our whole galaxy, because you'd have to be outside it (derr) [editline]11th November 2010[/editline] Wow that was patronising What I assume you meant is, how can they "see" the bubbles from inside the galaxy? The answer to that is presumably it's simply possible to infer it from the data. [editline]11th November 2010[/editline] wow I totally failed to explain anything!!
Looks like testicles.
My first thought was of the latest SGU episode [sp]Rush talked about a "structure" in the Microwave Background radiation[/sp]
Now, how can there be a "bubble" of gamma rays? Is it a bubble of gamma-ray emmiters? Or particles that reflect gamma? A cloud that emits gamma? What the fuck? Also, I thought relativistic jetting (What Canuhearme said about black holes throwing out most of what they consume) was supposed to be two straight diverging cones. This is just one big bubble, it looks as if it wasn't moving at all. Anybody determined the speed yet?

I expected a dyson sphere...

Is it wrong that I actually expected it to be a natural, gas-filaments-and-voids kind of thing rather than a Dyson sphere or an artificial structure? :geno:

[/QUOTE] Maybe it's the matter expelled from the black hole's jets, I'd imagine it would take some time to get rid of the energy created by the friction near a black hole, especially if it's clumped together. Still, that would assume our SBH was actively consuming matter in large amounts more then 50,000 years ago, which doesn't make sense.

[/QUOTE] Wouldn't it all radiate away as infrared? Wait, when the temperatures are high enough, it gives up on infrared and starts radiating as gamma and such, right?
huh??
[QUOTE=David29;25991778]When I read the title I immediately thought of this: [img_thumb]http://www.co-optimus.com/images/upload/image/2009/halo-ring.jpg[/img_thumb][/QUOTE] I like how everyone bandwaggons and gives him optimistic ratings even though, out of all of the potential artificial structures posted in this thread, a Halo ring would be the MOST PROBABLE of objects to find in deep space with our current technology. You wouldn't be able to spot something like The Citadel this far off. Even a Halo ring would be IMMENSELY difficult to chance upon, but... it would be considerably more easy to find it than The Citadel.
So from what I understand from the article is that; Our Super Massive Black Hole has ejected large amounts of radiation as a jet engine expels it's energy for thrust. As far as I know, this radiation is lethal to any galaxy in its way as well as the galaxy shooting it out in the first place. Perhaps our Solar System is far enough away from the Galactic Center that the radiation never hit us with nearly enough force to cause apocalyptic devastation? This fascinates me. Also I too imagined a giant structure built by aliens. I pictured a giant Mandelbrot though.
Now don't quote me on astrophysics but what if isn't a remains of a single huge outburst but rather formed due to the rotation of our galaxy? Or formed from the outbursts but in a period of time. Like, you know, when you make a whirlpool in a glass of water it seems to flow towards the center. It just gets trapped there.
[QUOTE=Haxxer;25982134]I instantly thought of the Geth superstructure God damnit stop using such an appealing thread title you douche-bag :frown:[/QUOTE] I would've thought of a Collector ship instead but Geth is reasonable too.
halo

[QUOTE=Acolyt3;26011878]The Halo is TINY, seriously, we could not possibly spot it with our technology.[/QUOTE] It's roughly the same size diametre of a planet. It would cause a TINY dipping of light intensity from a star as it passed by (if it wasn't already behind a planet passing in front of a star anyway). You're probably right, we'd need to wait for the next generation of exoplanet spotting technology to even stand a hope of picking up something like that, but it's a shit load more likely than a single lone spaceship, or a space station.
