Galactic winds are streams of high speed charged particles often observed blowing out of galaxies. With speeds of between 300 and 3,000 km/sec, these winds can either blow material out into the halo of the galaxy, possibly to mix with the hot X-ray emitting halo gas, or expel the matter from the galaxy completely to mix with the intergalactic medium. Galactic winds have two sources of energy: starbursts and active galactic nuclei (i.e. the supermassive black holes lurking in the centres of most galaxies).
In the case of starbursts, galactic winds are powered by high speed stellar winds ejected from newly formed massive stars(similar to the solar wind, only far more dense and energetic), and supernova explosions.
