Hubble, a telescope operated by Nasa, has discovered what it calls "protective shields" encircling faraway galaxies.
It has been theorised for quite some time by scientists, but its existence has now been proven for the first time.
The Large and Small Magellanic Clouds, our Milky Way's two largest neighbours, are having a terrible time as they tumble across space.
The Milky Way's gravitational field, in addition to their own orbits, is tearing them apart.
However, galaxies have maintained their structures and are even forming new stars.
How are stars still being formed if this gas was taken from these galaxies?
