Abstract.
Research in recent decades has seen many important advances in
understanding the role of jets and outflows in the star formation
process. Although, many open issues still remain, multi-wavelength
high resolution observations have provided unprecedented insights
into these bizarre phenomena. An overview of some of the current
research is given, in which great strides have been made in
addressing fundamental questions such as: how are jets generated?
what is the jet acceleration mechanism? how are jets collimated?
what is the relationship between accretion and ejection? how does
mass accretion proceed? do jets somehow extract angular momentum?
and finally, is there a universal mechanism for jet generation on
all scales from brown dwarfs to AGNs?
Key words: stars: pre-main sequence -- ISM: jets and outflows
