Galaxy with Molecular Outflow (IMAGE) European Space Agency Caption This is an artist's impression showing a galaxy with a molecular outflow. Herschel has discovered that such outflows can travel at 1000 km/s, which could deplete the galaxy of the gas needed for further star formation within one million to 100 million years.
