Hubble Spots a Celestial Bauble

<...a supernova explosion that took place four centuries ago...>

That's just not right. The timescale is equal to four centuries + (distance from cloud/speed of light).

Where's Jorrie when he's needed?

"PW" is correct.

Images being seen NOW are on the order of 160,000 years old (that is, unless we actually have NO CLUE WHATSOEVER as to how astonishingly-rapidly "Inflation" took place, and for what duration*) ...

The historic images being observed at this time are showing us what the 'bubble' looked like when it was approx 4 centuries of age.

* [But, of course, most of us are pretty darn certain that we know all we need to know about these "timeline-things" with an astonishing degree of accuracy ... in spite of all the new things we learn every day...]

"Peace"

A picture of this gas bubble was shown in yesterdays Daily Mail, and they said exactly what you said, that we were looking at it as it was 400 years ago!

same guest, here:

Xana~ replying-to post2 ... are you "Saying-what-you-mean & Meaning-what-you-say"...???

You state: "they said exactly what you said, that we were looking at it as it was 400 years ago!"

Yet, if you wil re-read my very simple post again, what I said was:

"Images being seen NOW are on the order of 160,000 years old (that is, unless we actually have NO CLUE WHATSOEVER as to how astonishingly-rapidly "Inflation" took place, and for what duration*) ... The historic images being observed at this time are showing us what the 'bubble' looked like when it was approx 4 centuries of age."

From those words, you should understand that the 'bubble' was 4 centuries of age back around 160,000 years ago...

(that is, ASSUMING that "Inflation" occurred at the precisely-calculated speed and for the precisely-calculated duration that scientists want to believe...)
