The European Space Agency’s Herschel infrared space observatory detected the extraordinary winds with streaming molecular gas, which are the material needed to make new stars, away from galaxies. The first time such molecular gas outflows have been observed in a sample of galaxies.Winds, which strips away the molecular gas and prevents further star formation from taking place, eventually leading to an elliptical galaxy, are 10,000 times faster than an Earth hurricanes.Researchers found that this wind could be created by the intense emission of light and particles from young stars, or by remnant shockwaves from the explosion of old stars. This discovery is very important, because these outflows are robbing the galaxy of the raw material which are necessary for star formation.
