The first stars in the universe, illustrated here as they explode as supernovae, likely formed just a few hundred million years after the Big Bang. Though the majority of the first stars are long gone, any that formed with masses less than 0.8 solar mass should still exist — but we've yet to find them. Is it just a matter of time before we discover these elusive stars, or is there a chance they never formed at all? You can read about researchers' efforts to understand if primordial magnetic fields in the early universe could have prevented the formation of low-mass stars in our AAS Nova highlight and the associated research article in the Astrophysical Journal Letters.
