This struck on April 22nd, a fast flowing solar wind that caught up and enveloped slower moving plasma. It created a CME like shock wave.

Apparently, supernovas result in stars exploding and disappearing but novas, once the dust settles, clearly continue in existence, despite generating excessive heat, or re-exploding.

It poses the question – why do comets and meteor streams weave in and out of Earth’s orbit, and their orbits disappear over time. Possibly the meteor streams left behind by the passae of a comet. It’s all to do with the Sun – giving them a kick. The Sun’s movement around the barycentre of our solar system seems to play a role. Not entirely, perhaps – but enough to exert movement. The research seems to replace a perceived common view that the planets caused comets and meteor streams to move in and out, providing the necessary kick. We may wonder what role the solar wind may play – buffeting comets and their debris.
