High-redshift galaxy in Sculptor constellation
UNCOVER-z13
UNCOVER-z13, as observed by the JWST on September 10, 2023
UNCOVER-z13 is a Lyman-Break galaxy, and not much more is known about the exact shape of the galaxy.
Discovery
UNCOVER-z13 was first observed when large amounts of gravitational lensing from Abell 2744 made the galaxy visible. Abell 2744 is around 3.5 billion light-years away from the Milky Way. The gravity of Abell 2744 warps the fabric of space-time sufficiently to magnify the light of more faraway galaxies. The James Webb Space Telescope used the gravitational lensing to discover UNCOVER-z13.
UNCOVER-z12
UNCOVER-z12 is a second galaxy which was discovered around the same time. UNCOVER-z12 has a redshift of 12.393, making it the fourth-most distant object ever observed. It is a Lyman-Break galaxy, and was discovered using the same methods as UNCOVER-z13.
