An article published in the journal “Astronomy & Astrophysics” reports a study of the magnetic fields of molecular clouds to understand their influence in the processes that lead to star formation. Astronomer Juan D. Soler of the Max Planck Institute for Astronomy in Heidelberg, Germany, used data collected by the Planck Surveyor space probe during its mission and the Herschel space telescope during the Gould Belt Survey to investigate the characteristics of the interstellar medium and especially molecular clouds. The study was published in 2019, but more spectacular images have been published by ESA of combined views of molecular clouds.
