ABSTRACT: In
this talk I will review the history of scientific
ideas concerning the origin of the solar system,
and I will update the topic from the perspective
of modern theories and observations of the formation
of stars and planetary systems. A major
surprise from investigations of the past two
decades is the realization that the birth processes
of stars and planets are much more violent and
dynamic than have been previously imagined. Swirling
disks of gas and dust condense into stars, but
they may also bring an inspiral and early demise
of many nascent planets. In their interactions
with the strongly magnetized central stars, such
disks may also generate powerful jets of gas
that spew a rain of molten rock throughout interplanetary
space, which later become incorporated as the
chondrules of chondritic meteorites. We end with
a discussion of the consequences for the types
of stars and planetary systems that result from
this activity.
