In HUbble vs Webb pictures we see the dying start picture. Why after 24 years it is still is a dying explosion scene. Shouldn’t be an instant?

Question

NASA released the latest pictures from Webb. You can see a link to a dying start here:

I am not sure, how it is possible that after 24 years, it seems the dying star explosion is still in a very similar size and shape. Can someone please what exactly we are observing in this picture.

Answer 1

This just goes to show how vast space really is.

That *is* an explosion, and the debris *is* going very fast, but it’s also very *big* and *far away*. So big and far away that, even after 24 years of motion, the spreading debris looks like it barely moved.
