Voyagers discover that Solar System is passing through a magnetizedgas cloud

The gas cloud is so magnetized that it resists being destroyed by nearby
supernova explosions even!

""The observed temperature and density of the local cloud do not provide
enough pressure to resist the 'crushing action' of the hot gas around
it," says Opher.

So how does the Fluff survive? The Voyagers have found an answer.

"Voyager data show that the Fluff is much more strongly magnetized than
anyone had previously suspected—between 4 and 5 microgauss*," says
Opher. "This magnetic field can provide the extra pressure required to
resist destruction.""
