Somebody is bound to ask "Why waste the money on this???" ...
... so allow me to preemptively provide a one word answer:
Science.
The oldest protocluster of galaxies found to date began clumping together some 13 billion years ago, when the universe was just 6 per cent of its current age. A global team of 36 astrophysicists led by the National Astronomical Observatory of Japan (NAOJ) studying data taken from the Keck and Gemini Observatory and the Subaru …
“However, we're surprised to see that Himiko was located not in the center of the protocluster, but on the edge 500 million light-years away from the center."
At 800 million years after the big bang, that would have covered a sizeable part of the universe, 10% or so maybe? Or do they mean it is now that far away?
The distance to Himiko wasn't stated in the article, and is apparently just another large galaxy within the z66OD protocluster. [z66OD is] "the oldest protocluster of galaxies found to date began clumping together some 13 billion years ago."
Basically the Reg article is click bait, but still demonstrates interesting science.
