Formation of stars at different evolution stages of the Universe is at the heart of the natural ranging from cosmogony to life origin studies. Indeed stars are the very fundamental building blocks of the Universe, which strongly influence and to some extent, control galaxy and planet formation and evolution. This topical collection is devoted to an in-depth examination of complex astrophysical phenomena of star formation via multi-wavelength observations and modeling. From their birth to their death, stars are playing a major role in chemical evolution of the matter and in the energy budget of galaxies via their radiation, their winds, and for the most massive ones via their explosion into supernovae. The first stars have provided the seeds of supermassive black holes with fundamental implications for the evolution of the observable Universe. The complex interplay of physical processes from gas and dust dynamics and cosmochemistry to nuclear physics leading to formation of protostars and protoclusters inside molecular clouds followed by their MHD and radiative feedback on the clouds are currently subjects of a great interest. Despite a lot of progress of the sensitive multi-wavelength observations and high performance modeling, a number of Star Formation Edited by Andrei Bykov, Corinne Charbonnel, Patrick Hennebelle, Alexandre Marcowith, Georges Meynet, Maurizio Falanga and Rudolf von Steiger

fundamental issues remain enigmatic as of yet. This is because the star formation process has a multi-scale nature with a strong non-linear feedback from radiation, MHD flows and non-thermal high energy particles. Magnetic fields, dust kinetics, as well as a number of non-thermal plasma processes play a role in evolution and dynamics of star-forming regions as we observe it from radio bands to gamma-rays. The amount of data on star formation obtained recently with the Herschel, HST, Gaia, XMM-Newton, Chandra and Fermi space telescopes, as well as with the ground based LOFAR, VLBI, ALMA, VLT and H.E.S.S. observatories is growing fast. These missions have produced vast and high-quality data bases. The forthcoming missions A
