Astronomers at helps a space telescope "Hubble" found out that in the Milky Way much more gas arrives, than leaves it. It is supposed that gas can arrive from the intergalactic environment: in particular, the Milky Way can select gas stocks at the galaxies satellites, using the gravitational field.
