MACS J1149
FAR OUT The gravity of the huge galaxy cluster MACS J1149 bent the light from a bright blue star (one of the faint points of light just above and to the left of the super bright central star in this image), letting it reach us from 9 billion light-years away.
The most distant star ever observed has been spotted, and its light comes from across two-thirds of the universe. That puts the star a whopping 9 billion light-years away.
Patrick Kelly at the University of California, Berkeley and his colleagues found the star in Hubble Space Telescope images of a galaxy cluster called MACS J1149. In April and May 2016, Kelly and his team saw a mysteriously fluctuating point of light in the galaxy cluster’s vicinity.

Shouldn't that be WAS 9 billion light-years away?

Shouldn't that be WAS 9 billion light-years away?
Yeah, a star bright enough to be seen from that distance had to be a short lived monster.

Shouldn't that be WAS 9 billion light-years away?
Probably. Unless the distance was adjusted to take into account the stars own movement over the last nine billion years.

And the expansion of space itself.
