I updated my above comment, after cooling off enough to actually open Wikipedia. Afaiu we see the remnants of the supernova as well, but it was far from the Pillars, and the wave will take some time to travel there—hundreds to a thousand years still. Otoh the part where the wiping-away was hypothesized but disconfirmed with Hubble, seems to be at odds with this account, because it says we should be seeing the disturbance already. It's all rather confusing.
