The most distant star ever spotted is 9 billion light-years away

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.

Constitutions are not designed for metaphysical or logical subtleties, for niceties of expression, for critical propriety, for elaborate shades of meaning, or for the exercise of philosophical acuteness or judicial research. They are instruments of a practical nature, founded on the common business of human life, adapted to common wants, designed for common use, and fitted for common understandings.

Yeah, a star bright enough to be seen from that distance had to be a short lived monster.

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.

Nothing should make a man happier than knowing his government couldn't care less about him.
I'd rather lose defending the constitution than win at its expense.
