Massive flows of molecular gas that escape galaxies have been observed directly for the first time ESA Herschel Space Observatory. The winds recorded to be extraordinary for both size and speed: The fastest observed so far moves at a speed of more than one thousand kilometers per second.

The discovery is significant because its stars form the interstellar gas in galaxies and streams as intense as those found in some of them could herald the arrest of the formation of new stars in those cosmic structures.
