Description
SN 1987A celebrated its 20 year anniversary on February 23. In this talk
I will review the immense importance of SN 1987A for the understanding
of the collapse of massive stars in general. In particular, the
mechanism behind the collapse and explosion of the core will be
summarized, including recent new developments of this longstanding
problem. The nucleosynthesis and the connection to other classes of
supernovae and gamma-ray bursts will be discussed. Finally, I will also
discuss the exciting ongoing collision between the ejecta and the
circumstellar ring of SN 1987A which provides us with a unique
laboratory for both shock physics and the acceleration of high energy
particles.
