Scientists find potentially oldest star in universe

Scientists think they may have found the oldest star in the known universe in a satellite galaxy of the Milky Way.

Known as AS0039, scientists think this may be the oldest star in existence due to its extremely low metal content.

Stars with low amounts of metal tend to be older – as they were most likely born when the universe was primarily made up of lighter elements such as gases.

AS0039 can be found in the Sculptor dwarf galaxy, a satellite of our own Milky Way.
