Default 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!

Yousuf Khan

""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.""

Perhaps it's enough magnetic repulsion to resist our future elliptical
encounter with Sirius that should by rights have an even stronger
diamagnetospheric molecular cloud of its own.

Perhaps it's enough magnetic repulsion to resist our future elliptical
encounter with Sirius, that should by rights have an even stronger
diamagnetospheric molecular cloud of its very own.

So, where's all the Usenet/newsgroup expertise on this one?

It would be a little difficult to have an elliptical or any other kind
of encounter with the Sirius system when the whole system is moving
away from us now.
