As the Sun and planets travel through space, the bubble in which they reside has been thought to resemble a comet, with a long tail and blunt nose.

I'd never have thought of us being in a 'bubble'!

Those Voyagers are amazing considering they are now over 30 years old and so far away from the Sun.  Still sending back valuable data too!   8-)
