Not at all. There have been a slew of recent papers that describe various types of novae around the galaxy. A great many of them are RECURRING novae. Basically the galaxy's a very dusty place, only the dust comes in relatively dense sheets that are 10s of light-years apart.

These "waves" of dust reach the Sun every 12,000 years or so. Gravity from the sun accretes this dust, which contains atoms much heavier than the Sun's usual H & He diet. After enough accretion, it forms a sort of shell around the Sun: trapped in by gravity, pushed out by the solar wind.

Except where does the Sun's energy go when there is a shell around it? Nowhere, that's where. Until there's too much pent up and boooooom. The Earth's sediment contains isotopes that are ONLY formed inside a nova. These are relatively short-lived, so they can't come from any supernova many light-years away. Plus they are deposited in the sediment in layers of progressively advanced age. 12,000 years apart.

It's about to happen again.

Also, it seems each time there is a Carrington level event JUST before that.
