Astronomers are on the hunt for magnetic fields in our galaxy that were born in the very early universe, because they could provide a new way to study the big bang.
Were not solving the puzzle of these fields but were kind of opening that door, says Sergio Martin-Alvarez at the University of Cambridge.
Magnetic fields are thought to play an important role in star formation within galaxies, and the Milky Way is home to various types …
