Some of the earliest galaxies to form in the Universe are sitting on our cosmic doorstep, according to a study.
These faint objects close to the Milky Way could be more than 13 billion years old, researchers from the universities of Durham and Harvard explain.
They formed upwards of a hundred million years after the Big Bang and contained some of the first stars to light up the cosmos.
The findings are published in the Astrophysical Journal.
