  1. It didn’t send dust anywhere, it grew in brightness and illuminated dust that was already around the star but the star wasn’t bright enough to illuminate the dust. It quickly grew in brightness then dimmed again so as the light traveled, it reflected off of the dust that was already there in an increasing size as the light traveled farther. This is called a [light echo](https://en.wikipedia.org/wiki/Light_echo).

  2. It’s really impossible to fathom how large that is, and how far the blast would go if it were to happen to our own sun.

  3. Every frame isn’t an actual picture, right? It looks to me like there were 4 or 5 pictures, and someone used Photoshop or a similar piece of software to morph one picture into another.
