IAU Symposium 250 on Massive Stars as Cosmic Engines will be hosted by the Institute for Astronomy at the University of Hawaii. The Institute for Astronomy is involved in the development and management of the observatories at Haleakala and Mauna Kea, one of the leading astronomical observatories in the world. The venue of the symposium is the Grand Hyatt Hotel on the beautiful island of Kauai.

The conference will focus on how massive stars shape the Universe, from the nearby Universe to high-redshift galaxies and the first generation of stars. Massive stars form in starbursts, pollute the interstellar medium (ISM), inject energy and momentum via their stellar winds and core-collapse supernovae (SNe), drive the ISM out of galaxies, polluting the intergalactic mediium. Direct detection of massive stars (via their UV continua and spectral lines) and of the products of their nucleosynthesis provides some of the most stringent constraints on the physical properties of galaxies at high redshifts, whether identified via their emission at a variety of wavelengths or by the absorption they produce in quasar spectra. Within the past few years, a direct connection has been established between certain core-collapse SNe and Gamma Ray Bursts (GRBs), supporting the collapsar model in which the GRB results from the death throes of a rapidly rotating WR star.

The massive star community - historically involved with studies of OB and Wolf-Rayet stars - has had a rich history of very successful IAU Symposia:

1971: IAU Symposium 49 in Argentina
1978: IAU Symposium 83 in Canada
1981: IAU Symposium 99 in Mexico
1985: IAU Symposium 116 in Greece
1990: IAU Symposium 143 in Indonesia
1994: IAU Symposium 163 in Italy
1998: IAU Symposium 193 in Mexico
2002: IAU Symposium 212 in Spain
