Here’s some more info:

It was captured by a special camera called a Rapatronic, a camera system able to take photographs at a frame rate of 10 million frames per second.

Waiting for the day smartphones have rapatronic cameras because why not.

Wikipedia-Entry for the Rapatronic Camera

It is hard to imagine something expanding to 300 meters diameter in 0.025sec

If anyone's interested in the bits sticking out the bottom of the bubble in the forth picture;

Shout-out to the cameraman for dying to get these images

Link to that fact?

I won't hold my breath.

Ah, a philosopher.

I remember during my early years there was a world wide fear about the upcoming test of a new Hydrogen Bomb. People feared that it might ignite the world's atmosphere.

What I’ve always found interesting about these images is how close the initial blasts look to virus/phages, particularly their heads.

You can argue that a nuclear blast is the end of the world, but a really intense virus could end us all just as easily, albeit taking a bit longer.

Some pictures look like a metroid from, well, Metroid.

Some of the images remind me of a metroid

wait how does it see inside the blast

That second picture isn't the inside of the blast even though it looks a little inside out. It's the evolution of the blast a fraction of a second later in time. Those bits sticking out the right and left sides are also sticking out the front pointing toward the camera, giving it an inside out appearance.

That first picture - and I am WILDLY speculating based on my understanding of how a nuclear bomb works - might be the initial triggering blast, which is a conventional explosive like any regular bomb. The second picture might be the first appearance of the actual nuclear explosion which moves faster and is overtaking the initial conventional blast.

Again, take that with a handful of salt. I'm just hazarding a guess.
