The James Webb Space Telescope (JWST) has discovered a tiny galaxy in the early universe that is growing rapidly as it forms stars at a tremendous rate, revealing more about the progenitors of galaxies such as our own.
The galaxy, referred to as RX J2129-z95, is seen at a redshift of 9.51. That number, which refers to the extent to which the galaxy's light has been stretched by the expansion of the universe, means that we are seeing it as it existed just 510 million years after the Big Bang.
