Most distant star to spotted — but how much further back in time could we see?

[Admin]

Even though Earendel is 50 times the mass of the sun, and millions of times brighter, we would not normally be able to see it. We can see it due to an alignment of the star with a large galaxy cluster in front of it whose gravity bends the light from the star to make it brighter and more focused – essentially creating a lens.

Astronomers spot most distant galaxy yet at 13.5 billion light-years away

Researchers have spotted what might be the farthest astronomical object ever found — a galaxy candi named HD1 that they estimate is 13.5 billion light-years away. Astronomers spot most distant galaxy yet at 13.5 billion light-years away : Read more

This documents the same problem when explaining the distance of this star. The article here states: "When we observe the star's light, we are looking at light that was emitted from the star 12.9 billion years ago — we call this the lookback time. That is just 900 million years after the Big Bang. But because the universe has also expanded rapidly in the time it took this light to reach us, Earendel is now 28 billion light years away from us."

The comoving radial distances obtained place Earendel in space that is expanding faster than c velocity relative to Earth today. We can assume this only it seems.
