Studies of the magnetic fields in our universe provide an excellent opportunity to confront monopoles with astrophysical observations. I will discuss two projects along this line: (1) New Parker-type bounds on the monopole flux in light of the modern understanding of cosmological magnetic fields, including galactic, intergalactic, and primordial fields. I will also present constraints on minicharged monopoles and magnetic black holes. (2) Monopole-antimonopole pair production in primordial magnetic fields. Here I will show that even superheavy monopoles can be produced in the early universe.
