PKS 1830-211 in a photo taken by the ALMA telescope.

PKS 1830-211 is a quasar with a redshift of z = 2.507. The quasar becomes visible to the earth through the gravitational lensing effect . The black hole in the quasar is called AGN PKS 1830-211 .

The quasar has a jet that is wrecked against the earth. With the help of the ALMA telescope, it was possible to prove that there are magnetic fields at the foot of the jet, which turned out to be Faraday rotation .
