NASA Hubble Space Telescope image of the galaxy cluster CL1358+62 has
uncovered a gravitationally-lensed image of a more distant galaxy located far
beyond the cluster. The gravitationally-lensed image appears as a
to the lower right of center. The galaxy's image is brightened,
magnified, and smeared into an arc-shape by the gravitational influence
of the intervening galaxy cluster, which acts like a gigantic lens.
Exact measurement of the distance from spectroscopic observations with
the W. M. Keck Observatory in Hawaii show the lensed galaxy is the farthest
ever seen. Its light is only reaching us now from a time when the universe
was but 7% its current age of approximately 14 billion years. This places
the young galaxy as far as 13 billion light-years away. The lensing
foreground cluster is 5 billion light-years from us.
