Briefly updated OP from my phone.

Note that this is the first of two black holes that we will be seeing pictures of. This first one is the much further away one so the next picture might be clearer.

I'm hoping the other black hole image will be a bit clearer.

Thats 8 stacks of 8 = 64 drives. If that was really 5PB it would need 78.125TB per drive.

That's a fairly misleading title. They created an image using their data, the title makes it seem as through they had a camera on a telescope. It's more of a beautiful pie chart than a picture of a black hole, but exciting none the less.

So when a large star dies, it collapses to form a blackhole, which creates so much energy it warps time and space and sucks in nearby matter?! Wow!

You just don't understand the science, which is no surprise. The title is not misleading at all.

It has to be very large for it to happen iirc, it may not even happen on the first cycle. Usually a normal sized star burns its fuel and implodes and gets hotter because it's now more dense. Then it burns it's previous spent fuel and repeats the cycle a few times until it's made iron which won't burn. Then you end up with different varieties of a glowing ball unless it blows it's self apart.
I can't remember all the fuel stages but the life of stars is really amazing, they keep living over and over again and rarely die out completely.

All gravity warps space-time, black holes just do it a lot more since they have so much gravity.

As White Owl said, it has to be a very, very massive star. Most stars are like our sun, relatively small starts that live a long time. Bigger stars have shorter lives because they use up their fuel more quickly.

Usually when a star like our sun dies, it turns into a white dwarf. When a super massive star dies, it goes nova, or super-nova and creates a nebula that births more, smaller stars. When a star even bigger than that collapses, it can form a super nova, a neutron star, or a black hole depending on its mass and density.

The misleading title had more to do with colloquial English than science, which is why NASA used the word "image" instead of picture. Nice try though.
