They show that there are a total of 58 billion dwarf stars, of which seven percent reside in the outer regions of our galaxy. This result is the most comprehensive model ever for the distribution of these stars.

The galaxy, named GN-z11, has a redshift of 11.1, which corresponds to 400 million years after the Big Bang when the universe was only three percent of its current age.

An international team of astronomers has pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5 percent of its present age with the discovery of an exceptionally luminous galaxy more than 13 billion light-years from Earth. The galaxy existed so long ago, it appears to be only 100 million years old.
