Holy fucking shit. We are going to die on 12/21/2012????????

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has captured these first, focused views of the supermassive black hole at the heart of our galaxy in high-energy X-ray light. The background image, taken in infrared light, shows the location of our Milky Way's humongous black hole, called Sagittarius A*, or Sgr A* for short. NuSTAR is the first telescope to be able to focus high-energy X-rays, giving astronomers a new tool for probing extreme objects such as black holes.

In the main image, the brightest white dot is the hottest material located closest to the black hole, and the surrounding pinkish blob is hot gas, likely belonging to a nearby supernova remnant. The time series at right shows a flare caught by NuSTAR over an observing period of two days in July; the middle panel shows the peak of the flare, when the black hole was consuming and heating matter to temperatures up to 180 million degrees Fahrenheit (100 million degrees Celsius).

The main image is composed of light seen at four different X-ray energies. Blue light represents energies of 10 to 30 kiloelectron volts (keV); green is 7 to 10 keV; and red is 3 to 7 keV. The time series shows light with energies of 3 to 30 keV.

The background image of the central region of our Milky Way was taken at shorter infrared wavelengths b

nothing will happen so i'm not the least bit worried

>blatant evidence in the OP
>NUH UH UR WRONG NOTHING WILL HAPPEN

it's ok to be scared, anon. we're all going together

>>5369307
So wait. Is this going to happen on the 21?

>>5369307
what the hell is that flare?
tell me why i should be worried?

>>5369307
I live in a basement; I don't care.

doesn't say shit about 21.12.2012
might as well happen on year 2055

>>5369315
>>5369320
yes the flare emitted a large amount of energy that will travel across the galaxy and destroy the planet and it will happen on the 21st due to when they saw the original light

Small part of me wishes these happenings were not 12/21/12 troloooooos

>In the OP
No.

The link he posted has no mention of his claims in it, and he gives no source (let alone a reliable one) for his claims about this.

>>5369254
jesus. Run-on Sentence award goes to this guy.

I think a gamma ray burst would have already wiped us out the second we observed it but don't quote me on that.

>>5369326
Generally speaking, the plasma wave behind such a burst follows at between 0.3% to 0.7% that we know of. Though we did once encounter a subatomic particle traveling at 0.99999% the speed of light. We called it the 'Oh My God' particle, because it had the mass of a softball.

Fortunately if such an event did take place, we'd observe a shift in emission from stars in its path due to a dramatic change in the bow shock of their magneto-pause.

Don't worry though. A quick glance at SOHO suggests a flair forming in a sunspot 3/4 the size of Jupiter may be in our near future. So if you want to panic, do so on the notion such energy would destroy all electronic grids and devices we currently use. Because when that happens, we'll kill ourselves fighting over food and medicine well before anything else has a chance.

nice try OPE

>in our near future

How near?

>>5369357
Oh silly. We observe gamma rays all the time. The OP isn't talking about a photon surge. He's talking about a cloud of protons which would literally blow the atmosphere off our planet while turning the surface to glass. The difference being mass and what protection we're afforded by earth's magnetic field.

Go to the SOHO observation website and look. The giant thing that looks like the sun has a boil made of fire is a magnetic irregularity on the surface. It's essentially creating a very, very large electromagnetic vortex which will eventually resolve itself by ejecting a plasma cloud resembling the fist of an angry god.

We can't say when it will fire other than 'soonish'. It just so happens the 'soonish' window may place the trajectory in line with our orbital plane.

It certainly won't kill us directly. It would just make a very powerful aurora appear in the sky. This is the result of an EMP blast wave more powerful than the simultaneous yield of every nuclear weapon on earth. I think you can guess why that might be a bad thing.

Worth noting: This actually happens fairly regularly. Last time it happened was around a century and a half ago. The energy was powerful enough to burnout telegraphs, the entire power grid and so on. Around 800-900 years ago it was powerful enough to inverse the polarity of naturally occurring rare earth magnets.

We don't have sufficient protection for our satellites. Nor for our power grid. We may in another 50 years or so, but we don't at present. So, short of HAARP proving to be some ludicrous scheme of warping the ionosphere to deflect such a blast by supercharging our EM field, it's just a matter of time.

If you commit suicide can I have all your stuff?

Intensity drops off as R^(-2) guys.

But I've seen much more intimidating sunspots that have fired off X-flares at Earth from following SpaceWeather and nothing much came of it. As a matter of fact, the current sunspots look pretty weak compared to the massive one that fired of the X6 (or something close to that) October 2011.

> there is something behind the light that was optically observed from NASA, such as x rays, gamma rays, alpha beta and cosmic particles following at a slightly slower speed than that of light.

Nobel prize winning work, apparently gamma rays and x-rays otherwise known as light, travel at less than the speed of light. Incredible. Or you're an idiot who didn't know enough to make this the least bit convincing. You have provided zero evidence of anything.

>>5369359
>We called it the 'Oh My God' particle, because it had the mass of a softball.
No it mad the kinetic energy of a small sports ball, not the mass energy.

And no, there is nothing unusual happening at the Sun. You are just making shit up, you couldn't even spell flare correctly.

>>5369390
Geomagnetic storms are nothing like EMPs. You you have no idea what you are talking about. The probability of a large flare is low right now, what you think you see is worthless given you have no understanding of these things.

>>5369416

Then you're not looking at the data in a complete manner. We're getting fluctuations of photon bombardment an order of magnitude above the norm and without the corresponding solar wind that should follow. Sort of like when hot wind starts blowing the wrong direction before a hurricane.

Thar be a storm a brewin'.

>>5369404

Good 'ol inverse square law. We don't give you enough appreciation.

>>5369428
>>5369390
You're that guy fanning the flames on /pol/ to scare people, aren't you?

>>5369427

It was an analogy for laymen, genius. I'm well aware of the differences, regardless of what your pompous little undergraduate brain might think.

Go compare the historical data trends for yourself, oh-wise-one. Lets see if you've the first clue how to interpret it. I'll even give you a hint: check the k-flux pattern.

>>5369428
The solar wind is days behind the light, you don't know what you're talking about.

>>5369446

I know you may not learn this in grade school but we can observe fluctuation and derive the anticipated plasma output days before it reaches earth. So when we look and it's not there but a giant band of plasma arcing between sunspots is, we can tell that there's an anomalous magnetic event transpiring.

Ugh, why don't you just go back to watching Sagan and feeling superior about yourself? Unless you enjoy advertising the creme that is lower-middle tier American public education..

>>5369447
Made up nonsense, 'k-flux" doesn't mean anything.

>>5369458
Nothing looks out of the ordinary to me, and I'd wager I've done more (IE: any) actual study of space weather than you.

>>5369458
Maybe you should have said you were relying on models not solar wind observations then. You have shown no inside knowledge of this subject, stop acting superior.
