The furthest star ever observed at 9 billion light years away, wow....
That was an interesting read, thank you.

Well the view of it, as posted, is at least 31 days older (NOW than it was THEN)

Hubble has been in orbit for 28 years, and I am still waiting for a decent picture

The light took 9 billion years from that galaxy to reach us,so in fact that galaxy will be now 9 billion years older today.
When the light of that galaxy left the galaxy the galaxy was probably only 3 billion years old,and if we were able to see it today it probably would not look the same as it did back then.

If alpha Centauri exploded today we would still be seeing it as a normal star in the night sky for another 4.3 years even though it has actually turned to dust and gas.
It's a little bit like estmating the actual size of the universe. If the Big Bang occurred 13.4 billion years ago, and there is a speed limit in the universe of "c" how can the size of the universe be over 90 billion light years across?

I thought they fixed the Hubble mirror? ( the world's most expensive piece of glass or whatever material it is made from)

I think a bit of reading will give you the answers you require.
Google your question.

If the Universe formed in the Big Band event about 13.4 Billion Years ago, and the Universe has a speed limit equal to the speed of light how can the Size of the Universe be about 94 Billion light years?

As I said do some reading you can get a more precise explanation than I can give you.
I am sure you're capable of doing that ?

Hi Peter
I hope you are well.
The Big Bang Theory has it that it is space that is expanding and the speed limit applies to matter and not space so there is no conflict here.
However read up on the Cosmic egg and how it apparently figured in the discussions of cosmology for twenty years before the Big Bang if you want to wonder about things.
I have been thinking about the theory recently...observation doesn't take us past the observatiin of the background radiation but the theory does.
Although I subscribe to mainstream and accept its rules I like the steady state universe approach which has been rejected.
But within the Big Bang model there is no inconsistency with Special Relativity. The model has no flaws.

Alex The Supreme Being of this fine establishment has surfaced from the chasm of Hades ladies and gentlemen and must surely realise that for a steady state model of the universe to hold matter must appear from nothingness at some non zero rate in order to comply with observation and data humans have amassed thus far
The cosmic egg was cracked, beaten, cooked and served as scrambled egg with toast a very long time ago Alex
