What's more, the explosion is ongoing and has been continuing for the last 100 million years, releasing as much energy as hundreds of millions of gamma ray bursts.

The blast is generated by the largest black hole in the known universe, a gravitational monster over 10 billion times the mass of our Sun.

Astronomers calculate this behemoth has consumed almost 600 million times the mass of the Sun in order to generate such a powerful explosion.
Shown in pink are vast cavities each over 600,000 light-years in diameter, blasted out by powerful supersonic jets from the gargantuan galaxy at the very heart of this image.

These cavities have displaced a trillion suns' worth of mass and have been filled with magnetised, extremely high-energy electrons emitting radio waves, which were detected by the Very Large Array radio telescope.

Crazy stuff. Universe ready to blow us up at anytime

Shit like that is fucking mind boggling

I can't even comprehend how terrifying that would be

how

i legit dont understand or comprehend this

A black hole can generate an explosion?
How does that not support that our universe comes from a black hole?

at a certain point the terror meter breaks and you're just trying to stay alive in whatever tin can floating in whatever medium is available.

Each of the pink blobs on the picture are 3-4 times larger than our entire galaxy

I thought those star looking things were galaxies.

It sounds like this isn't really an explosion.

Black holes shoot jets of particles from its top and bottom sides, right? (though I don't really understand why)

The article calls them explosions, but I think it's talking about these same jets, except it's coming from an extremely huge black hole.

Is that a real-color photo?

As a general rule, nearly all space photos are re-colored. Most are taken in IR or other non-visible frequencies. (Correct me if i'm wrong.)

Should you see a nebula with your own eyes, you probably wouldn't see anything interesting or pretty.

I think "explosion" is just an easier way to say "massive expulsions of high-speed particles normally seen in most black-holes".

so uhhh, can someone explain the three different masses listed here to me?

The black-hole itself is super-massive.

If we think of the suns mass as M, we can use that as a measure of mass for other objects in the galaxy.

For example, Sirius is about 2.02M, and one of the most massive stars we've observed, Eta Carinae, is somewhere between 100 and 150M.

This black-hole is 10billionM.

As far as the other mass listed, it's simply what they've calculated the Black Hole has "eaten" based on observations of the material being ejected.

Okay, the black hole itself has a mass more than ten billion times that of our own sun. However, over the last 100 million years, it has devoured a galaxy or such that has a mass of 600 million times that of our Sun, which has triggered this ongoing explosion (eruption?) of energy. As stars get eaten by a black hole, they get crushed down and go supernova. Some of the mass of the star gets gobbled up by the black hole's event horizon, but other parts of the star's mass get blasted out faster than the black hole's escape velocity.

So, over the last 100 million years (from the perspective of our perception, it really happened a long time ago), this black hole has been eating stars at the rate of about 6 a year, if all of the stars had the same mass of our Sun. The resulting regular chain reaction of novas has created a massive plume of energetic matter that has displaced and pushed around the 10 billion sun-masses of matter mentioned in the article.

At least that's what I think is happening based on my somewhat simple understanding of astrophysics.

Is this Hawking raditation then or something else?

Pretty amazing to think our entire world could just blow up at any minute. Or maybe it couldn't. One or the other really. Just incredible how god do that.

This is something else. The jets shot out from black holes aren't fully understood but it's likely they're caused by the interaction between the mass and spin of the black hole and the magnetic fields created near the black hole. It accelerates particles to near the speed of light and fires them off like guns in two different directions away from the black hole (and perpendicular to the accretion disk). These jets were first observed as Quasars but we now understand that Quasars are actually supermassive galactic center black holes.

For something more close to home, our own Milky Way is due for a collision with Andromeda in some 4 billion years IIRC. The resulting black hole formed from that will still only be fraction of this one.

It's not an explosion like the ones we are thinking of (like a bomb or something), considering it has been ongoing for millions of years. It is still pretty amazing and mind boggling though.
