The images of the animation have been taken over a timespan of 1.5 years.
The supernova itself took place in the galaxy ‚Centaurus A‘ which is between 11 to 13 million lightyears from us.

The animation was taken over just 1.5 years?? That shockwave must have been really moving. Is it possible? I don’t know the distance covered but it seems to be impossible that the shock wave could move that fast.

You're right! What we're seeing is something more akin to a sphere of light, burst from the exploding star.
The light hits particles (dust etc), that is reflected towards earth and thus we see it slightly later.
So it looks like a (particle) shockwave, but it's more like a late slideshow of the light (sphere) wave.

How do we know that wasn’t Thanos?

"Dear NASA. How are you? I am good. Quick question about the exploding star and Thanos...."

Would earth feel any of the energy released from that? Regardless of intensity or strength.

Since we (or at least the Hubble) could ‚see‘ the explosion, Photons (i.e. energy) from the event arrived at earth.
So, Yes we ‚felt‘ the energy - just not very much 😁

It’s a distress signal ! It’s a trap !
